Aquaculture, 2004
The bullseye puffer (Sphoeroides annulatus) is a species with potential for aquaculture. However, preliminary studies on the biology and reproduction of the species in captivity have failed to produce consistent success at hatching. In this study, the effect of aeration and water treatment (filtration and ultraviolet (UV) sterilisation) on percentage ...

Abstract Hatchery-produced Sphoeroides annulatus were studied from fertilized egg until day 32 post-hatch to examine the digestive tract development and to evaluate its digestive capacity during the larval period. Fish larvae were progressively fed microalgae, rotifers, Artemia nauplii and a formulated microdiet.

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

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 ...

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 ...

We analysed the effects of salinity on survival, growth and the osmoregulatory capacity (OC) of puffer fish larvae (Sphoeroides annulatus). In experiment 1, we compared the growth of larvae maintained at a constant temperature (28 ± 0.5 °C) under seven salinity levels (5, 12, 19, 26, 33, 35 and 40 psu) over a 28-day period.

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 ...
