Selective mortality during the larval and juvenile stages of snappers (Lutjanidae) and great barracuda Sphyraena barracuda
Selective mortality during the early life stages in marine organisms can affect the magnitude and composition of recruitment, yet these processes have not been examined in economically important predatory coral reef fishes. Utilizing 3 different stage-specific sampling techniques (shipboard plankton tows, larval light traps, juvenile surveys/seines), we repeatedly sampled multiple cohorts of 3 ...

متن کاملReproductive biology of the yellow snapper , Lutjanus argentiventris ( Pisces , Lutjanidae ) , from the Mexican central Pacific
The yellow snapper, Lutjanus argentiventris, is a commercial species along the Pacific coast, yet few studies have been carried out on its reproductive biology. Monthly samplings of the artisanal fishery off the coast of Jalisco, Mexico, were made from 1998 to 2008. Mean total length and weight of analyzed specimens were 32.6 cm (±0.13) and 567.3 g (±9.15), respectively. A total of 945 females ...
متن کاملSpatial ecology and residency patterns of adult great barracuda (Sphyraena barracuda) in coastal waters of The Bahamas
Great barracuda (Sphyraena barracuda) were implanted with acoustic telemetry transmitters (n = 42) and monitored within a stationary acoustic receiver array (n = 53 receivers) in The Bahamas to examine residency, seasonal movements, and habitat use. Barracuda were monitored for up to 980 days and remained within the array area »33% (median value) of the time. Most tagged barracuda were transien...
