Efecto de la temperatura y salinidad del agua en la incubación de huevos de botete diana Sphoeroides annulatus
The effects of different water temperatures (22, 25, 28 and 31ºC) and salinities between 0 and 60 psu (with intervals of 5 psu) on egg incubation of the bullseye puffer (Sphoeroides annulatus) were evaluated in this study. The embryos could not develop at 22ºC and the highest hatching rate for norma...

| Sumario: | The effects of different water temperatures (22, 25, 28 and 31ºC) and salinities between 0 and 60 psu (with intervals of 5 psu) on egg incubation of the bullseye puffer (Sphoeroides annulatus) were evaluated in this study. The embryos could not develop at 22ºC and the highest hatching rate for normal larvae was observed at 28ºC. At 0, 50, 55 and 60 psu larvae were unable to develop. Highest hatching rates were obtained at 25, 30 and 35 psu. It was concluded that water temperature and salinity affects the incubation period, embryo development stage and larval survival of the bullseye puffer. |
