Laboratory spawning and larval rearing studies were conducted with red drum (Scianenops ocellata) and southern flounder (Paralichthys lethostigma) from 1974 through 1977. Adult fish were placed in 29.92 kl spawning tanks equipped with biological filters and subjected to photoperiods and temperatures regulated to simulate seasonal variations. Red drum spawned 52 times producing 6.0 X 107 eggs. Southern flounder spawned 13 times producing 1.2 X 105 eggs. Eggs were collected and incubated, and larvae were reared to fingerling size. This paper describes techniques used to produce fingerling...

Spotted seatrout were maintained in an indoor tank (6 x 3.3 x 1.5m). Temperature and light were adjusted to simulate the seasons. When the light regime equaled 15 hr light and 9 hr dark and the temperature was 26 C. the spotted seatrout began to spawn. They continued to spawn during each of 13 consecutive months for a total of 82 spawns. Eggs were collected from the filter box with glass beakers and placed in 74-liter aquaria. The eggs hatched after 18 hr. Newly hatched seatrout were fed rotifers (Brachionis plicatilisland brine shrimp (Artemia sp.). Descriptions and illustrations are...
