Stress Response of Red Snapper (Lutjanus argentimaculatus) Exposed to Sublethal Concentrations of Crude Oil

Feeding biomechanics of juvenile red snapper (Lutjanus

INTRODUCTION Ecomorphological studies are predicated on identifying patterns among morphology, behavioral performance and ecology (Wainwright, 1994), and have been utilized to test a variety of hypotheses concerning the relationships between feeding performance and foraging ecology among teleosts (e.g. Clifton and Motta, 1988; Wainwright, 1996). Ecomorphological studies are also useful in exami...

toxicity of water soluble fractions of crude oil to fish, lutjanus argentimaculatus and shrimp, penaeus monodon

the acute toxicity of a malaysian crude oil to red snapper, lutjanus argentimaculatus, blacktiger shrimp and penaeus monodon were investigated. the animals were exposed to water solublefractions (wsf) of crude oil in a flow-through bioassay system and the toxicants were analyzed by gaschromatography (gc) and gas chromatography and mass spectrometer (gc-ms). the 96 h lc50 valuesof the wsf of cru...

Systemic infection of Kudoa lutjanus n. sp. (Myxozoa: Myxosporea) in red snapper Lutjanus erythropterus from Taiwan.

A new species of Kudoa lutjanus n. sp. (Myxosporea) is described from the brain and internal organs of cultured red snapper Lutjanus erythropterus from Taiwan. The fish, 260 to 390 g in weight, exhibited anorexia and poor appetite and swam in the surface water during outbreaks. Cumulative mortality was about 1% during a period of 3 wk. The red snapper exhibited numerous creamy-white pseudocysts...

Assessment of Mercury Bioaccumulation in Zebra Cichlid (Cichlasoma Nigrofasciatum) Exposed to Sublethal Concentrations of Permethrin

Background: Aquatic ecosystems are frequently subjected to contamination by toxic heavy metals and pesticides, yet very little is known about the influence of pesticides on bioaccumulation of heavy metals in aquatic organisms. Mercury is a toxic metal with no known biological benefit to organisms. Bioavailability of mercury in aquatic environments depends on biological and non-biological parame...

Cryopreservation of mutton snapper ( Lutjanus analis) sperm.

This study aimed to develop a protocol of semen cryopreservation of the mutton snapper Lutjanus analis. The interaction between three extenders ( pH 6.1; 7.8 and 8.2) , two concentrations of dimethyl sulfoxide ( DMSO, 5 and 10%) and three cooling rates ( -90; -60 and -30°C.min-1) on the sperm motility rate and motility time were analyzed by a factorial experiment. A sample of 30 fishes ( 1,261 ...
