Abstract

Thorax ganglion was reported as a source of stimulating hormone for gonad development. The aim of this research was to study the development of mud crab (Scylla olivaceous) oocytes cultured in in vitro medium supplemented with thoracic ganglion extracts of Neopisesarma lafondi. Immature crabs with 110 mm carapace width were collected from the mouth of Bawana Marana Rivers, Maros Regency of South Sulawesi, Indonesia. Pieces of ovarian tissues from those crabs were incubated within 24 hours in culture medium (Medium-199 with 100 IU/ml Penicilin-G) supplemented with 2 mg/ml thoracicganglion extract. Result showed that the diameter of mud crab oocytes was increased in congruent with the incubation time. The development was prominent after in vitro incubation for 8 hours (P

Abstract

Sea cucumber (Holothuria sp.) viscera, commonly considered as waste in the sea cucumber processing industry, has been proven to possess significant nutritional value be utilized as a potential functional feed ingredient. This study aimed to evaluate the nutritional content of sea cucumber viscera and assess its potential use as a supplementary feed ingredient in aquaculture. Proximate analysis results indicated that sea cucumber viscera contain high crude protein (39.69 ± 0.38 %) and crude fat (26.62 ± 0.41 %). A complete profile of essential amino acids was identified, with arginine (6,621.7 mg/kg) being the highest. Furthermore, sea cucumber viscera were dominated by polyunsaturated fatty acids (PUFA) at 52.89 %, including EPA (6.73 %) and DHA (7.46 %). Significant vitamin and mineral contents were also found, such as vitamin A (4.16 µg/g), vitamin C (84.67 µg/g), calcium (1,701.72 mg/L), and magnesium (542.38 mg/L). These findings highlight the potential of sea cucumber viscera as a crucial source of energy, protein, essential fatty acids, vitamins, and minerals for the growth and health of aquaculture organisms. Utilizing sea cucumber viscera as a feed ingredient not only provides a high-nutritional alternative feed but also supports circular economy and zero-waste principles in marine waste management.
