Weaning of bullseye puffer (Sphoeroides annulatus) from live food to microparticulate diets made with decapsulated cysts of Artemia and fishmeal

Aquaculture International, 2003
Two experiments were carried out to test microparticulate diets forweaning hatchery-produced larvae and juveniles of bullseye pufferSphoeroides annulatus. The diets were formulated with differentprotein sources: diet 1 with a combination of decapsulated cysts ofArtemia and fishmeal, and diet 2 with a combination offishmeal, squid, tuna gonad and shrimp

Effect of LHRHa on the expression of stress‐related molecules in the ovary of wild caught Sphoeroides annulatus held in captivity

Journal of Fish Biology, 2005
Two cDNA fragments corresponding to a heat shock protein and a cell death receptor were isolated from the ovary of the bullseye puffer Sphoeroides annulatus that were arrested in vitellogenesis or induced to ovulate with LHRHa. A reduced expression of both genes was observed following injections of LHRHa, suggesting these genes may participate in ...

Behavioral thermoregulation, temperature tolerance and oxygen consumption in the Mexican bullseye puffer fish, Sphoeroides annulatus Jenyns (1842), acclimated to different temperatures

Journal of Thermal Biology, 2011
Abstract An inverse and unusual relationship was found between preferred temperature and acclimation temperature in the bullseye puffer, Sphoeroides annulatus . The final preferendum temperature (PT) was 26.8 °C. The critical thermal maxima (CTMax) were 37.7, 38.8, 40.0, 40.8 and 41.3 °C where the temperatures of acclimation were 19, 22, 25, 28 and ...

Nutrition and feeding research in the spotted rose snapper (Lutjanus guttatus) and bullseye puffer (Sphoeroides annulatus), new species for marine aquaculture

Fish Physiology and Biochemistry, 2008
The spotted rose snapper (Lutjanus guttatus) and bullseye puffer (Sphoeroides annulatus) are fish species from the tropical Eastern Pacific for which controlled production of larvae and juveniles has been accomplished in recent years. Diverse topics relating to their biology and aquaculture production are currently under study, in particular the ...
