| Spawning requirements: |
Fish spawn in the spring when water
temperatures reach 50 F. Eggs are contained within a gelatinous ribbon. A 0.5 lb female
will produce 10,000-20,000 eggs. Eggs hatch in approximately two weeks at 53 F. Spawns may
be obtained by stripping eggs from ripe females and mixing with milt from males in a dry
container, mixed thoroughly and then water is added to activate the sperm and permit
fertilization. |
Most common
production systems: |
Ponds stocked at 200,000-300,000
fry per acre for production of 3-5 inch fingerlings. For food fish estimate 1,500-2,500
lbs. per acre. |
