The researchers studied how different levels of salt in water affect the development and survival of Takifugu flavidus embryos and larvae. They found that the best salinity range for hatching eggs is between 20 and 50. Larvae grow best in lower salinity levels, with 15-20 being optimal. The survival rate of larvae is highest at salinities between 10 and 30. Overall, the study shows that the salinity of the water plays a crucial role in the growth and survival of Takifugu flavidus embryos and larvae.
