Reproductive biology of a diandric protogynous hermaphrodite, the serranid
Two species of Serranids
, Mycteroperca venenosa and Mycteroperca interstitialis, have a low incidence, however, their sighting frequency suggests that their numbers have been increasing in the Florida Keys.
A second species of small planktivorus serranid
, originally described as Serranus incisus by Colin (1978), was transferred to Parasphyraenops by Johnson & Smith-Vaniz (1987).
Fine-scale movement studies of other serranids
report strong spawning site fidelity to a single spawning location (Zeller 1998; Starr et al.
Within the tropical Pacific, only Palau and Pohnpei have developed long-term management protocols at the national level specifically to protect commercially important serranids
In addition, clinids, serranids
, sciaenids, pomadasyids, and pleuronectiformes were noted at lower abundance.
and protogynous species--in the Gulf of Mexico (GOM) were likely due to size-selective or sex-selective harvesting, or both, that was affected by fish behavior (Coleman et al.
Some of the forms mentioned include sciaenids (drums and croakers), pleuronectids and bothids (right- and left-eyed flatfishes), serranids
(basses), atherinids (silversides), mugilids (mullets), gobiids (gobies), clupeids (herrings), and other nearshore forms.
leopardus may be limited and are consistent with the presumed sedentary (reef-specific) habit of most serranids
after settlement (e.
Abundant otoliths of sciaenids (drums and croakers), pleuronectids and bothids (right- and left-eyed flatfishes), serranids
(basses), atherinids (silversides), mugilids (mullets), clupeids (herrings), and several other families that suggest a nearshore environment, are also present.
Their method has been widely rejected because it is valid only for determinate spawners, and both the above-mentioned serranids
are indeterminate spawners (Garcia-Diaz et al.
The spotted sand bass is the only known hermaphrodite among serranids
common to southern California (Hastings 1989).
In our study, YOY reef fish taxa, such as serranids
, lutjanids, and haemulids, were more abundant in seagrass habitats than they were in tidal-creek habitats, except for gray snapper (Lutjanus griseus).
Seasonal and ephemeral color changes in serranids
are well known and are most commonly associated with the social behavior (i.
In addition, this growth rate is more typical of tropical serranids
and resides among the taster growing fishes (e.
