Abstract

Blue swimming crab (Portunus pelagicus) is one type of crustacean that has great potential to be cultivated. Crab seed production activities are carried out to support the availability of crab seeds so as to reduce fishing activities in nature. Data collection during observation using the survey method, namely by making observations in the field. Seed production activities were carried out since container preparation, preparation of rearing media water, broodstock selection, broodstock rearing, egg hatching, larval rearing, feed management, water quality management, pest and disease management and harvesting. Egg fecundity of 750,000 eggs, egg fertilization rate of 83.60%, egg hatching rate of 76% and larval survival rate of 36.55% were obtained.

Abstract

Knowledge related to Bonylip Barb (Osteochilus vittatus Valenciennes, 1842) embryo development is essential as a first step to developing a suitable fish hatchery method to support higher egg quality and quantity, thus increasing fry production. The purpose of the observation is to study and provide information on the development of bonylip barb fish embryos, which has been limited to academics and the public until now. Observations were carried out in April 2023 at the Muntilan Fish Health and Environmental Testing Laboratory, Central Java. Bonylip Barb embryo development takes 23 hours and 11 minutes after fertilization. This process is influenced by factors that limit the embryo's development until hatching.
