Impacts of Replacing Fish Meal With Duck By-Product Meal in Diets on Growth Performance, Feed Utilization, and Economic Efficiency of Olive Flounder (<i>Paralichthys olivaceus</i>). [PDF]
Fish feeds are generally more expensive than livestock feeds because they contain high amounts of costly fish meal (FM). Therefore, formulating low‐FM diets is necessary for the sustainability of aquaculture. This study evaluates impacts of FM replacement with duck by‐product meal (DBM) in diets for olive flounder (Paralichthys olivaceus) on growth ...

Diagnosis of Weissellosis in Cultured Rainbow Trout in Costa Rica Further Evidence Emergence of Weissella tructae as Important Pathogen of Salmonids in Latin America. [PDF]
Weissellosis, caused by the Gram‐positive (GP) lactic acid bacterium Weissella tructae, is an emerging disease of farmed rainbow trout (Oncorhynchus mykiss) reported in Asia, South and North America. In this study, W. tructae was isolated from diseased cultured trout in Costa Rica on four facilities with mortalities seen predominantly in sub‐adult (100–

Improved Induced-Spawning Protocol for the Spotted Rose Snapper (Lutjanus guttatus) [PDF]
An improved protocol for hormonal induction of spawning in spotted rose snapper (Lutjanus guttatus) resulted in increased spawning efficiency in newly-caught wild breeders and wild-caught adults maintained in captivity for more than a year. A controlled-release delivery system (implant) based on an ethylene-vinyl acetate copolymer (EVAc) matrix was ...

Reproduction of Lutjanus guttatus (Perciformes: Lutjanidae) captured in the Mexican Central Pacific
Research on the reproduction of snappers helps to manage and conserve them. The spotted rose snapper Lutjanus guttatus is a gonochoric species caught year-round in Navidad Bay, Jalisco, Mexico. This work aims to analyze the reproductive aspects of the spotted snapper L. guttatus caught in Navidad Bay on the southern coast of Jalisco, Mexico.
