— Spawning behavior and development of spotted sand bass Paralabrax maculatofasciatus were studied in the laboratory. Captive fish (15–20 cm standard length) spawned in 100-L aquaria at 24 C and 35 ppt salinity with a controlled photoperiod (13 h

Red drum, Sciaenops ocellatus, were raised from juveniles averaging 2.5 g to adults averaging 6.1 kg. Growth rates with simple experimental starter and grower feeds were similar to those with one of the best-performing commercial starter feeds for ma

Red drum reared from captive-spawned eggs were used in a 2 × 4 factorial experiment comparing eight diets with soybean oil (SBO) or menhaden oil (MHO) added to a basal diet (about 3.4% lipid from practical ingredients) at 1.5, 5.2, 9.0, or 12.7%. Tr

Nassau groupers Epinephelus striatus held in a 37-m3 concrete raceway were conditioned to spawn 3 mo later than in their home waters. After being held in the raceway for 15 mo, four female and two male groupers spawned voluntarily over a 4-d period i

The Nassau grouper Epinephelus striatus has historically supported reef fisheries throughout much of the tropical western Atlantic Ocean. However, fisheries have severely declined in most areas because of overfishing. These declines have inspired eff

The current available information on spawning by serranid fishes in captivity is reviewed. Much work has been done on members of the family Serranidae because of their value as food or ornamental fish. At least 31 species have been induced to ovulate

Sunshine bass, a hybrid of female white bass (Morone chrysops) × male striped bass (Morone saxatilis), were raised in tanks to mean weights of 1,333 g on two experimental feeds and 894 g on a commercial feed, 19 months after hatching. During 6–19

Nassau grouper Epinephelus striurus females ovulated 48–51 h after the first of two intramuscular injections of human chorionic gonadotropin given 24 h apart (usually 0.7 IU/gram body weight). Typical spawns contained 400,000–600,000 eggs. With f

This paper presents some results from phase-1 research into developing a beam steerer based on micro-mechanical diffractive elements. The position of these elements is electrostatically controlled, to allow dynamic programming of a 2D phase function.
