摘要：The effect of photoperiod on development and hatchmg success of the obscure puffer (Takifugn obscurus) was studied by determining total hatch, total mortality, viability of newly hatched larvae 24 h post-hatch, and time to 50% hatch for embryos incubated at four photoperiod regimes: 24L:0D, 12L: 12D, 0L:24D, and natural photoperiod. The results indicated that total hatch, total mortality, and viability of newly hatched larvae were not significantly different among photoperiod treatments (P>0.05). However, time to 50% hatch decreased with increasing length of photoperiod. Hatching time for embryos incubated under continuous light was significantly shorter than the other three treatments (P < 0.05).
