Lunar Periodicity in the Spawning of Red Drum in Aquaculture

摘要

In response to a dramatic decline in the population of red drum Sciaenops ocellatus in Texas coastal waters in the 1970s, the Texas Parks and Wildlife Department established a stock enhancement program. A fish hatchery was establishec in Corpus Christi with the purpose of spawning and releasing fingerlings into Texas bays (Matlock et al. 1984, McEachron et al. 1995, Vega et al. 2012). With the success of this program, Sea Center Texas (SCT) was established in Lake Jackson. In addition to red drum, both hatcheries also currently produce spotted seatrout Cynoscion nebulosus and southern flounder Paralichthys letliostigma for stock enhancement along the entire Texas coast.
