walleyes ranged in size from 13.6 - 22 inches, weighing .9 -
4.35 pounds. Females ranged from 13.8 - 28.8 inches in length
and 1.2 - 10.7 pounds in weight. The average Swartswood Lake
walleye was 19.8 inches long, exceeding the minimum size limit
of 18 inches, and weighed 3.41 pounds. A remarkable 33 females
weighed over 6 pounds - about 10% of the catch!
catch was composed of 217 males and 135 females. Seventy-three
females were spawned to produce 9.6 million eggs, an average
of 131,630 eggs per female. Three million of the 9.6 million
eggs were shipped as surplus to the PA
Fish and Boat Commission.
1.2 million 3-day old fry were set up in hatchery ponds for
growout and another 1.2 million fry were stocked in the Delaware
River between Poxono and Belvidere. The expected hatchery pond
production of walleye fingerlings is 300,000 two-inchers and
April 19th, the Hackettstown Hatchery trapnetting crew moved
their operation north to Greenwood Lake in search of muskellunge
broodstock. The trapnetters were successful, capturing a total
of 31 muskies, the highest total since 37 were captured in 1999.
muskies produced a total of 712,303 eggs, an average of 41,900
eggs per female. Eggs hatched at a rate of about 50%, which
is comparable to other years. Muskie fry will be raised to advanced
fingerlings (10-12 inches) in hatchery tanks and ponds at which
time they will be stocked.
All broodstock collected for use in the hatchery programs were
transported to the hatchery where the spawn taking operations
are performed by hatchery personnel. Within a week of spawning
the fish are returned to the waters where they were collected.
All adult muskies handled at the hatchery over the past several
years have been tagged with orange streamer tags inserted near
the base of the dorsal fin. The tags bear the message "CALL
HACKETTSTOWN HATCHERY (908) 852-4950" along with a tag number.
Anglers who call in to report catching a tagged fish will be
told when the fish was tagged, and its length and weight at
the time of tagging. Tagged fish from both lakes were captured
during the 2007 broodstock collection.
