Extinction vulnerability in marine populations
There is an urgent need for improved methods of detecting marine extinctions at various spatial scales, and for predicting the vulnerability of species.
Critical science gaps impede use of no-take fishery reserves.
Criteria for the Diagnosis of Hermaphroditism in Fishes
The strongest indicators of protandry are transitional individuals whose gonads contain degenerating testicular tissue and developing ovarian tissue, and experimental production of transitional or sex-reversed individuals through manipulation of the social system may identify both protogyny and prot andry.
Synopsis of biological data on the Nassau grouper, Ephinephelus striatus (Bloch 1792), and the Jewfish, E. itajara (Lichtenstein, 1822)
Information on the biology, fishery resources, explotiation patterns, management, and conservation status of two species of grouper-the Nassau grouper, Epinephelus striatus, and the jewfish,
Are aggregation-fisheries sustainable? Reef fish fisheries as a case study
Reef fish spawning aggregations are attractive and often lucrative to fish but particularly vulnerable to fishing, with many cases of declines or extirpations. While awareness of the risks of
Reproduction of reef fishery species
It is not clear whether aggregation spawning and the preference for specific spawning locations evolved largely for the benefit of larval dispersal or survival, to enable males and females that live somewhat dispersed to come together or for some other reason.
Trouble on the reef: the imperative for managing vulnerable and valuable fisheries

Reef fishes are significant socially, nutritionally and economically, yet biologically they are vulnerable to both over-exploitation and degradation of their habitat. Their importance in the tropics
Size, composition, and spatial structure of the annual spawning aggregation of the red hind, Epinephelus guttatus (Pisces : Serranidae)
It is suggested that aggregations function primarily to enable males and females to find mates and that spawning is not random but occurs in clusters containing one male and a few females.
Near extinction of a highly fecund fish: The one that nearly got away
This case study is that of the highly threatened Chinese bahaba, Bahaba taipingensis, a member of the Sciaenidae, and an example of a fecund and commercially important group of fishes that appears to be especially vulnerable to fishing.
