Feed is a main component to support fish growth. Formulated feed is made up of various ingredients, both animal and plant-based. The plant-based ingredient commonly used as a source of protein in fish feed formulation is soybean meal. However, soybean meal is still imported from abroad. Therefore, there is a need for alternative plant-based ingredients that can be used as a protein source to su…
One of the obstacles in snakehead fish farming is the availability of juvenile. The method that can be applied to increase juvenile production, is through hormonal stimulation such as thyroxine hormone. The purpose of this study was to determine the effect of thyroxine hormone for the duration of hatching, the percentage of egg hatching, growth, the percentage of abnormalities, and survival. Th…
