Prospecting the effects on abalone (H. discus) growth under low-salinity stress after feeding citrus peel (cp) and ecklonia cava disuse (ecd) as feed additives

Abstract

This study addressed the effects of adding citrus peel (CP) and Ecklonia cava disuse extract (ECD) in the diet of abalones, which are a highly utilized marine species in Korea. As interest in abalone farming is increasing around the fishing community, the installation of land tanks and fish farms on the southern coast and Jeju Island in South Korea is spreading remarkably. In order to create the best opportunities for survival and reproduction, immunity to disease, and growth potential of abalones, we must consider the diet implemented in abalone farming. The survival rate of abalone has shown positive results when their diet is supplemented with CP and ECD. Our research also concluded that the addition of ECD may have a significant effect on the abalone growth and physiology.
