Four new species of Ceratomyxa Thélohan, 1892 are described from the gall bladders of fishes collected off Lizard Island, Australia. These species are characterised using a combination of morphometric and molecular data. Ceratomyxa bartholomewae sp. n. is described from Hyporhamphus dussumieri (Valenciennes) (family Hemirhamphidae); C. koieae sp. n. is described from Sphyraena forsteri Cuvier (...

Recent exploration of Miocene-age deposits at Nosy Makamby, a small island ~50 km southwest of Mahajanga city in northwestern Madagascar, has led to the recovery of a large sample [82] of isolated barracuda teeth (Sphyraena sp.). in a tropical marine fauna that also includes diverse marine invertebrates, chondrichthyans, bony fishes, turtles, crocodylians, and sirenians. Characteristically for ...

The great barracuda (Sphyraena barracuda) is a widespread, ecologically and socioeconomically important coastal fish, yet very little is known about its larvae. We examined spawning and larval ecology of Western Atlantic sphyraenids using monthly ichthyoplankton samples collected over 2 years along a transect spanning the east–west axis of the Straits of Florida (SOF). Samples were dominated by...

Since 2010, with the creation of the National Cancer Institute, the Argentine Republic has been tackling the battle against cancer as a genuine public health problem. Today in Argentina, there is a "cancer policy" whose pillars are prevention, education, assistance, and research. In this article, we provide information about the incidence and mortality of the tumours most common in adults and c...

The study investigates feeding habits of thermophilic species and with subtropical affinity in the fishing catch Bay Medulin (northeastern Adriatic Sea), contributes to knowledge about their presence recently extended distributional range. In our methodology, Seriola dumerili, Sphyraena sphyraena, Lichia amia, Coryphaena hippurus, Caranx crysos, Pomatomus saltatrix, incidence Trachinotus ovatus...

Age and growth of the European barracuda, Sphyraena sphyraena, were determined by examining sagittal otoliths belonging to fish sampled in eastern Adriatic Sea, as northernmost region Mediterranean. A total 113 specimens (59 females, 53 males, one individual indeterminate sex), ranging from 23.4 42.5 cm length, analyzed. The maximum observed age was 5 years for both females this barracuda popul...

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...

This study attempts to look into the energetic status of demersal fish species with their maturity stages and evaluate their energetic condition. Demersal fish species from wild were captured, total length and weight of each fish were measured and gonads were observed, weighted and collected with fish flesh. Gonadosomatic index, water content of gonad and flesh and gonadal and somatic caloric v...

Analyses of ciguatoxicity in the great barracuda Sphyraena barracuda and quantity of toxic benthic dinoflagellates on coastal reefs (correlated with the number of cases of human ciguatera intoxications in Puerto Rico) were used to construct a model formulated on data obtained during the period of 1985-1988. The validity of the proposed model has been questioned by recent data obtained during th...
