The eastern brown pelican (Pelecanus occidentalis carolinensis) ceased nesting in Louisiana in 1961 and the species completely disappeared by 1963. From 1968 to 1980, the Louisiana Department of Wildlife and Fisheries and Florida Game and Fresh Water Fish Commission reintroduced 1,276 pelicans at 3 release sites in southeastern Louisiana. Two restored nesting populations were established, 1 at North Island in the Chandeleur Island chain and 1 at Queen Bess/Camp Island in Barataria Bay. The Queen Bess/Camp Island colony fledged 2,751 birds between 1971 and 1984. North Island production was...

Biomodal spawning peaks, as determined by the gonadosomatic index, were noted for the spotted seatrout (Cynoscion nebulosus) in the Barataria Bay, Louisiana, system for 1976 and 1978. Males matured earlier in the season and at a smaller size than females. Males were found to have sound producing capabilities. Fish spawned throughout the bay regardless of water depth or substrate. Spawning seemed to occur in the northern portion of the bay later than in the southern portion. Photoperiod and temperature were the only exogenous factors found to have a direct relationship with spawning.
