Bureau of Freshwater Fisheries
Robert Soldwedel, Chief

The Bureau of Freshwater Fisheries manages the freshwater fish populations in the state’s rivers, streams, ponds, lakes and reservoirs. The bureau works to ensure that the more than 500,000 men, women and children who cast their lines in state waters each year have good experiences.

One aspect of this work is conducting inventories of water bodies around the state and formulating management plans. A comprehensive warmwater management plan has been developed and is in the process of being implemented.

Another part of the bureau’s work is raising more than one million fish at the Hackettstown and Pequest hatcheries for stocking throughout the state. Recent emphasis has been on the warmwater/coolwater program with such species as walleye, muskellunge and northern pike being produced in increasing numbers. Work contiunes at Hackettstown on the new fish culture facility.

Fish Culture

Almost fifteen years after the construction of the Pequest Trout Hatchery, construction of a new warmwater/coolwater facility at the Charles O. Hayford Hatchery in Hackettstown is underway. Through Green Acres funding a new aquaculture building is being erected and is scheduled to be operational by June of 1999. This new facility will allow for a substantial increase in the production of a variety of warmwater/coolwater species, through modern aquaculture technology, give greater system security and decrease overall production costs. This will mean improved fishing opportunities for the angling public. In addition to the renovation of aquaculture equipment there are plans to construct a visitor center and reopen the facility to the public in the near future.

With the anticipated completion of the intensive culture building in 1999 there were no significant upgrades to the existing intensive system. However, during most of January and February this past year one of our larger ponds was dredged using Division equipment and manpower.

Although the Hackettstown Hatchery strives to be self-sufficient, we do depend on out of state sources for our hybrid striped bass eggs. However this past year we received no fish or eggs from out-of state. Unfortunately, South Carolina who normally supplies us with young hybrid bass had broodstock problems and was not able to meet our requests.

From the Pequest Trout Hatchery a total of 750,355 trout were shipped to the public waters of New Jersey during the 1997—1998 production cycle. This number includes fish stocked during the fall 1997 and spring 1998 seasons. In addition, 218,960 trout, comprised of surplus fingerlings, were shipped after the spring stocking period. These fish are used in the cooperative interstate trading program. The average size of these fish is around four inches.

The cost of producing trout at Pequest was $3.53 per pound this year. This results in a cost of $1.50 per fish stocked. Click to view summary tables of species raised and their numbers at Hackettstown and Pequest.

Fisheries Research and Management

The development of an electronic database of all fisheries sampling, stocking and fish health information made significant progress this fiscal year. When completed, the database will cross-reference all the information from hatchery and management files for a given water.

Considerable effort was expended this year obtaining biological and physical information for the Lake Inventory Program, as well as for waters where management recommendations were needed. Sampling was done on eleven ponds in eleven counties.

Most notable this year was the completion of the inventory of Lake Hopatcong (Morris/Sussex counties). Water sampling documented the lack of summer trout habitat, a condition that has recently developed. This resulted in a recommendation to change the lake’s management from a “holdover” trout lake to a “put and take” trout lake. This would entail a reduction in the number of trout stocked annually. This was opposed by the Knee Deep Club which stewards the lake and no changes were implemented.

Anadromous Fisheries

The Delaware River American shad run was once again monitored with hydroacoustic equipment mounted on the Route 202 bridge in Lambertville. From April 1 through May 31, 1998, a total of 392,700 adult shad were estimated to have passed the sampling site.

As in previous years, a monitoring program for outmigrating juvenile American shad was conducted at five representative stations on the Delaware River. A total of 16,382 juvenile shad were collected in 59 seine hauls with an average catch of 278 shad per haul. Although this number does not approach the 1996 record of 456 per haul, it is still above the 18-year average of 221.

Fish passage through the Island Farm Weir Fish Ladder, located at the confluence of the Raritan and Millstone rivers, continues to be monitored with the use of a remote camera and time lapse VCR. To date, 24 species of fish including American shad, northern pike, hybrid striped bass, walleye, brown trout, largemouth bass and smallmouth bass have been documented using this facility.

Coldwater Fisheries

The annual fall inventory of lake trout in Round Valley Reservoir took place in 1997. Only one of 170 sampled lakers was fin-clipped, indicating that natural reproduction continues to support the fishery. Trends in the body condition of the lake trout during the 1993 to 1997 period were determined. Average condition of lake trout in 1997 was considerably lower than that of 1996. Yet there is no downward trend in the condition factor since the 1997 condition does not fall below the 1993 to 1995 period.

In Merrill Creek Reservoir lake trout averaging 7.5” and marked with a left pectoral fin clip were stocked in the fall. The reservoir’s low productivity is apparently contributing to observed poor growth. Consequently fewer lakers were stocked as part of an overall plan to the improve the fishery. Additionally, regulations allowing anglers to harvest small lakers (15-24”) were implemented in 1998 with the intent of reducing the population to a level more compatible with reservoir productivity. In addition 20,000 alewives were stocked to bolster the population of this important forage fish.

In an attempt to establish sea-run brown trout in the Manasquan River, 16,000 standard brown trout were stocked in the lower river in October 1997. It is anticipated that the young brown trout may, after a period of freshwater residence, migrate to the saltwater estuary and/or ocean to grow and mature. After one or two years these fish should return to the river to spawn. In March 1998 one of these fish was caught in the Point Pleasant Canal, at which time it had grown approximately five inches and attained a weight of 1.3 pounds. The next day an angler caught one of a similar weight in the ocean off Spring Lake. A creel census on opening day 1988 in the Manasquan River failed to turn up any of these fin-clipped browns.

Warmwater and Coolwater Fisheries

Tiger/True-Strain Muskellunge

As a result of our stocking efforts interest in muskie fishing continues to increase. The NJ Chapter of Muskies, Inc., reports that their membership is an impressive 150. Their members’ catch reports indicate that the numbers and the average size of muskies caught has increased from last year. A state record muskie of 42 pounds, 13 ounces was taken in 1998 from Monksville Reservoir.

Hackettstown Hatchery personnel were very successful at capturing muskellunge broodfish in-state. A total of 55 adults were captured from three waterbodies, the largest being 46 inches and weighing 28.4 pounds from Monksville Reservoir. As a result of the hatchery’s in-state broodstock collection, 539,000 tiger muskie and 863,000 muskellunge eggs were produced. This resulted in the stocking of approximately 15,000 tigers and 6,200 pure-strain muskies.

Striped bass hybrid

The fact that no striped bass hybrids were stocked this year because of their unavailability from South Carolina and budget concerns should have minimal impacts on the fisheries at Spruce Run Reservoir and Lake Hopatcong but may have a significant effect at Manasquan Reservoir where the fishery is relatively new. At that location, the potential looks good as hybrids up to 4.8 pounds have been netted by us this year, which indicates good growth since their stocking in 1996.

Walleye

This was our final year of field sampling at Monksville Reservoir under the Federal Aid to Sportfish Restoration Program to evaluate the introduction of walleyes. The reservoir is continuing to be the primary source of walleye broodfish. A total of 132 adult walleyes were captured by trap netting in the spring of 1998. From these fish the Hackettstown Hatchery produced 3.7 million eggs and reared 291,700 pond fingerlings (1.8 in. av.) and 39,480 advanced fingerlings (4.3 in. av. ) for subsequent stocking in four waterbodies. Due to a proposed water lowering associated with a major dam reconstruction project, the 1997 stocking of Cannistear Reservoir was canceled. This is unfortunate as the Newark Watershed Office has reported a number of walleye caught at Cannistear Reservoir this year. At Lake Hopatcong catches are becoming more routine.

Other Management Activities

Artificial Habitat Projects

Considerable progress was made this year in planning and installing artificial habitat for fish in both our lakes and streams.

A project was initiated on the Musconetcong River where it flows through a cemetery in Hackettstown. Minimal bank cover there, due to constant mowing and trimming, contributed to bank erosion and limited instream fish habitat. With our urging the cemetery board of trustees applied for and received NRCS’ Wildlife Habitat Incentive Program (WHIP) funds. Additional Department funds were made available, through the North Jersey RC&D program for the establishment of a riparian buffer.

A similar project was entered into with the Warren County Board of Recreation which applied for WHIP funds to enhance a portion of Lopatcong Creek. The property is actively farmed and little bank cover exists due to constant mowing to the water’s edge. It should make an excellent demonstration project when completed.

Through the National Fish and Wildlife Foundation and in conjunction with the U.S Fish and Wildlife Service, a grant proposal was prepared for a habitat improvement program for Spruce Run Reservoir. This grant for weighted Christmas trees, felled shoreline trees and the re-introduction of aquatic vegetation was approved for $6,000. Four hundred twenty-five Christmas trees were collected by the Town of Clinton which were pruned and weighted with cinder blocks by volunteers from the Division’s WCC program and the NJ BASS Federation. The trees were placed at various points within the reservoir by Division biologists.

A different approach to the construction of artificial habitat devices was initiated in Pemberton Lake, Burlington County, in July 1998. There, artificial habitat devices were constructed from PVC pipe, discarded car tires and surveyors ribbon. Essentially these devices resemble a large pin cushion. We deployed 25 of these units in each of two areas in about six to eight feet of water. One site was placed adjacent to a handicapped-accessible fishing pier and the other was placed centrally for boat anglers. It is anticipated that these devices will increase angler success for bass and panfish by concentrating populations of these shelter-oriented species.


Bureau of Wildlife Management
Fred Carlson, Chief

The Bureau of Wildlife Management is responsible for the development and maintenance of a productive, diversified wildlife resource and the habitat on which it depends. This is accomplished through scientifically sound management and research programs which provide economic, aesthetic, and recreational benefits for the citizens of New Jersey.

One of the bureau’s many challenges is balancing use of the land with wildlife needs. As development continues and habitat is lost, this becomes an increasingly complex and formidable task.

Deer Management

At least 150,000 deer occupy the state’s 4,734 square miles of deer range prior to the start of the deer season. Population densities range from less than 10 to more than 70 deer per square mile.

Management efforts fall mainly into two categories: 1) collecting information about deer populations, their health, and impacts on people and ecosystems and, 2) the use of that information to develop, revise and implement programs to manage deer in a manner that best serves the public interest. The goals of deer management are to provide for healthy populations on suitable habitat, maintain population densities compatible with people’s activities (farming, gardening, driving), and maximize the recreational and economic benefits derived from this renewable natural resource.

Cooperative deer management programs continued with the Atlantic, Hunterdon, Morris and Union County Park Systems, Fort Dix Military Reservation, Earle Naval Weapons Station , Lakehurst Naval Air Engineering Center, the FAA William J. Hughes Technical Center, Picatinny Arsenal, Cape May National Wildlife Refuge (NWR), Edwin B. Forsythe NWR, Great Swamp NWR, Supawna Meadows NWR, Wallkill River NWR, Round Valley Recreation Area, Monmouth Battlefield State Park and Newark Watershed Conservation and Development Corporation. A cooperative program with the Division of Parks and Forestry was implemented at High Point State Park.

The Community-Based Deer Management Program, a cooperative agreement between the Division and local government agencies allowing for the development of alternative deer population control measures, was continued at the Watchung Reservation in Union County. The county is proceeding with a five-year program to reduce deer density. The Morris County Park Commission has also utilized the program.

A total of 59,551 deer were reported harvested during the 1997-98 deer seasons, the second largest harvest on record. Season records were established in the Permit Muzzleloader and Permit Shotgun seasons. Factors contributing to the exceptional harvest include the following: population management strategies of herd reduction on two-thirds of the State’s deer range; expansion of the “Bonus Deer Tag” program during the Fall Bow season; additional days of Permit Shotgun hunting in January; allowing the Winter Bow season to run concurrently with the Permit Muzzleloader and Permit Shotgun seasons; and generally good weather throughout the six deer seasons. The total harvest included 32,340 antlerless deer, a new record. The antlerless harvest is vital to reducing deer populations. Considerable progress has been made during the past several years to reduce deer herds that have been inflicting damage on agricultural crops, reducing bio-diversity and creating traffic hazards.

The High Point State Park deer management effort utilized an eleven-day hunt during November to reduce deer overpopulation. Poor regeneration of Atlantic white cedar trees and high winter deer mortalities in the Kuser Natural Area accentuated the need for population control in the park. The cull was very successful with a total of 305 deer removed, including 127 antlered male deer and 178 antlerless deer.

Upland Wildlife and Furbearer Research

Black bear winter den work was performed on 8 females and their newborn cubs. One thousand thirteen sightings were reported and 301 monetary damage complaints were investigated. Fifty-four black bear mortalities were recorded, compared to 32 in 1997, 31 in 1996 and 19 in 1995. Nine of the mortalities were tagged bears legally harvested in New York or Pennsylvania. Two tagged bears were struck and killed by vehicles in New York. Of the 43 mortalities occurring in New Jersey, 39 were vehicle kills, one was illegally killed, one was euthanized, one was shot by a park ranger after it displayed extremely aggressive behavior, and one died of unknown causes.

Firearm hunters and trappers were surveyed in 1997-98 to estimate harvest of upland wildlife and furbearer species. The value of fur harvested was estimated to be $369,088. Annual surveys of woodcock and mourning dove were conducted in cooperation with the US Fish and Wildlife Service. Neither survey showed any significant change in numbers.

The eastern coyote continues to increase its distribution and numbers. Twenty-four sightings were reported and 45 mortalities were investigated. Cause of death was determined for 44 of the 45 moralities as follows: vehicle kill (24), trapping (7), hunting (11), unknown causes (1) and destroyed due to disease (2). Mortalities were reported from Atlantic (2), Morris (11), Warren (7), Sussex (9), Hunterdon (4), Somerset (4), Cumberland (5), Passaic (1), Middlesex (1) and Bergen (1) counties. Sightings were reported from 12 counties including the above and Mercer and Ocean counties. The second coyote season was held; a total of 998 coyote permits were issued and 11 coyotes were harvested.

Wild Turkey Restoration

Wild turkeys continue to thrive throughout much of the Garden State since re-introduction efforts began in 1977. The large game birds are now found in 20 counties and with the population estimated to number 14,000 in the fall of 1997. Trap and transfer operations are continuing with the goal of completing restoration of the species by the year 2000. No wild turkeys were captured in the winter of 1997-98 because of mild weather conditions and other demands on project staff.

An estimated ten thousand people hunt wild turkeys in New Jersey. Spring turkey hunting generated an estimated 2.5 million dollars in commerce. Expenditures were for food, lodging, gasoline and equipment. Survey results indicate that the average turkey hunter is well-educated, male, forty years of age and has five years of turkey hunting experience.

Turkey hunters enjoyed the first fall hunting season in nearly a century in December, 1997. The Division issued more than 2600 permits and hunters reported taking 168 turkeys in the three day season. Staff maintained 65 check stations to collect data on harvested turkeys in the spring and fall seasons. Spring gobbler hunting has become a well-established and extremely popular tradition among New Jersey’s turkey hunters since the first season in 1981. A total of 14,043 permits were issued for the 1998 spring season. Spring hunters harvested a record 2,420 turkeys during the five-week season. The birds were in excellent condition due to abundant food supplies and a very mild winter.

Waterfowl Ecology and Management

The Waterfowl Ecology and Management Program is responsible for research and management of more than 30 species of migratory waterfowl. Activities are conducted in association with other state and federal agencies which comprise the Atlantic Flyway Council (AFC). Research is designed to measure waterfowl population size, production, survival, harvest, movements and habitat use. Information collected in New Jersey is combined with that collected by other agencies in eastern North America and is used to develop population management recommendations, including hunting season lengths, bag limits, season dates and establishment of special seasons.

In cooperation with the AFC and the US Fish and Wildlife Service, several surveys are conducted each year to measure waterfowl population parameters. These include snow goose, Atlantic brant and tundra swan productivity, Spring Waterfowl, wood duck call-count and Breeding Waterfowl. The Mid-Winter Waterfowl Survey resulted in a count of 523,904 total waterfowl.

A manuscript documenting that border collies were effective in excluding geese from the property studied was submitted to a scientific journal. New Jersey’s resident Canada goose population has increased to more than 80,000 birds and generates numerous nuisance complaints. Unfortunately, the migrant population has declined during recent years complicating management efforts. Accordingly, special seasons (September and Winter) were developed to target resident geese. An estimated 17,715 geese were harvested in the two seasons.

Project personnel work cooperatively with a variety of state and federal agencies and universities on other waterfowl related projects. The Bureau of Land Management was provided with technical assistance, project biologists gave three presentations at a Canada goose symposium hosted by the Monmouth County Water Resources Association and wintering greater scaup and their foods were collected for contaminant analysis in conjunction with the USFWS and the University of Connecticut. More than 13,000 reference morphological (body) measurements of Canada geese were analyzed to enable accurately assigning harvested geese to the resident or migrant population. Staff assisted Canadian biologists in banding 2,000 migrant Canada geese in northern Quebec and represented the AFC as a consultant to the USFWS Regulations Committee. Project biologists hosted several international waterfowl management meetings including the AFC Technical Section, the Black Duck Population Joint Venture, the Arctic Goose Joint Venture Habitat Working Group and CONSEP (steel shot) groups.

Wildlife Control Unit

The Wildlife Control Unit provides assistance to the agricultural community and general public in controlling wildlife damage to crops and property, as well as responding to damage and nuisance complaints. While unit personnel field all kinds of complaints about wildlife, the primary focus of the unit is the solution of problems involving white-tailed deer, black bears, beaver and coyotes. This past year responses were made to 3,495 wildlife nuisance and damage complaints, an increase of 612 over the 2,883 in FY97.

Agricultural deer damage is a major concern with 951 complaints. Solutions to deer damage complaints include application of repellents, placement of fences and use of permits to shoot. Three hundred and fifty rolls of mesh wire and 100 rolls of barbed wire were distributed. Farmers and residential property owners received 627 gallons of deer repellent for use on crops and ornamental shrubbery. There were 547 permits to shoot deer issued to farmers who were experiencing losses.

The black bear population has increased dramatically in the past decade. Interactions and conflicts between bears and people occur on a daily basis in four northern counties. Bears complaints are second to deer complaints in volume, numbering 825 from eight counties in FY98. Complaints ranged in severity from destruction of birdfeeders, trash cans and beehives to losses of livestock and home entries. It is estimated that black bears caused more than $120,000 in property damage. Unit personnel live-trapped and applied aversive conditioning to more than twenty bears. Problems will continue to escalate as bear numbers increase and development continues.

Beaver are found throughout the state and frequently cause damage to trees andhomes. Nearly four dozen beaver were trapped in FY98; some were live-trapped and relocated; others were destroyed. It is increasingly difficult to find suitable places to release problem beaver in this fast-developing state.

Game Bird Propagation

With the combined effort of employees and good weather, 50,000 pheasants were raised for stocking this year.

A new exotic bird exhibit (120’x30’) was constructed with materials salvaged from the Forked River Game Farm. This exhibit replaced the old pens and enhances the experience for our visitors.
