Among vertebrates, teleost fish exhibit a considerably wide range of sex determination patterns that may be influenced by extrinsic parameters. However even for model fish species like the zebrafish Danio rerio the precise mechanisms involved in primary sex determination have not been studied extensively. The zebrafish, a gonochoristic species, is lacking discernible sex chromosomes and the sex...
Cryptosporidium molnari n. sp. is described from two teleost fish, the gilthead sea bream (Sparus aurata L.) and the European sea bass (Dicentrarchus labrax L.). The parasite was found mainly in the stomach epithelium and seldom in the intestine. Oocysts were almost spherical, with four naked sporozoites and a prominent residuum, and measured 3.23–5.45 £ 3.02–5.04 (mean 4.72 £ 4.47) mm in the t...
A tagging study was conducted off the New Jersey coast to study sex change in Black Sea Bass Centropristis striata as a function of size, age, and spawning season. Throughout 2011–2013, 3,670 fish were measured and 1,498 were tagged from research, charter, and commercial fishing vessels. Of the tagged fish, 437 were recaptured. Size at 50% probability of sex change was 355 mm TL; the proportion...
The leather bass Dermatolepis dermatolepis (Boulenger, 1895) is a poorly known grouper living on coral and rocky reefs in the eastern Pacific Ocean. One of only three species in the genus Dermatolepis (family Serranidae, subfamily Epinephelinae), the leather bass distribution ranges from southern California to Ecuador, including the Gulf of California, the Galapagos Islands and other offshore i...
