Protection of red snapper (Lutjanus sanguineus) against Vibrio alginolyticus with a DNA vaccine containing flagellin flaA gene

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...

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...

Evaluation of Immunogenicity, Protective Immunity on Aquaculture Pathogenic Vibrio and Fermentation of Vibrio alginolyticus Flagellin FlaC Protein

Background: Vibrio are the main pathogenic bacteria in aquaculture. The flagellin protein C (FlaC) of Vibrio alginolyticus has good immunogenicity and the prospect of potential application in a vaccine. Objectives: We aimed to evaluate the immunogenicity, protective immunity, and prokaryotic expression fermentation of V. alginolyticu...

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

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 ...
