The effects of delayed first feeding on the nutritional condition of tiger grouper, Epinephelus fuscoguttatus (Forsskål, 1775), larvae were examined under controlled conditions. Larval gut epithelium development and morphometric changes of the larva

It is important to understand the physiological stress responses in juvenile Pacific bluefin tuna (PBF), Thunnus orientalis, when transporting them from land-based tanks to sea cages, to develop countermeasures against mass mortality and enhance surv

In this study, we aimed to clarify the mechanism of sinking death during the larval stage of Pacific Bluefin tuna Thunnus orientalis by investigating the effects of swimming performance on sinking death, using a behavioral approach. Swimming performa

It is necessary to understand the processes involved in sinking death in Pacific bluefin tuna Thunnus orientalis aquaculture in order to develop methods to prevent or minimize this problem. We observed the nighttime vertical distribution of Pacific b

The effects of different aeration rates at night to prevent sinking syndrome-related death (SSRD) of the tiger grouper, Epinephelus fuscoguttatus were examined. The aeration rates were fixed at 300 mL min−1 at daytime (07:00–19:00 hours)

This study examined the influence of swimbladder inflation (SBI) failure on mortality (Experiment 1), lordotic deformity (Experiment 2) and growth (Experiment 1, 2) in Pacific bluefin tuna, Thunnus orientalis, postflexion larvae and juveniles by prod

This study investigated the optimal timing of day to promote initial swimbladder inflation (ISI) for improved Pacific bluefin tuna (PBT), Thunnus orientalis, larval survival. Larval swimbladder inflation frequency was compared based on three experime
