Abstract

The addition of multi-amino acids to the culture media for Portunus pelagicus crab larvae accelerates the metamorphosis rate from the zoea to megalopa stages. The research aims to examine the effect of adding multiple amino acids to the rearing media and determine the best dosage on the rate of acceleration of metamorphosis (stage transfer) of P. pelagicus crab larvae from zoea to megalopa stages. Test samples are taken daily to see the development of larvae or larval stage index. The test animals used in this research were zoea-1 stage crab larvae stocked at 100 individuals/L density. The container used in this research was a black plastic basin with a water volume of 30 liters. Treatment doses of amino acids were 0, 150, 200, and 250 ppm with 3 repetitions each. The research results show that administering multi-amino acids in the rearing media can accelerate the transfer rate of crab larvae stages. The fastest rate of acceleration of metamorphosis from zoea to megalopa was produced at a treatment dose of 250 ppm for 10 days, and the longest was produced at a dose of 0 ppm for 13 days. Stage transfer between sub-zoea takes 2-3 days for metamorphosis, and zoea to megalopa takes 10-13 days.

Abstract

Freshwater lobster (Cherax quadricarinatus) is a fishery commodity with high economic value, and market demand continues to increase. However, one of the main challenges in cultivating freshwater lobsters is the low survival rate of fry, especially in the early stages of development. This research aims to optimize the dosage of a combination of amino acids and dissolved glucose to meet the nutritional needs of freshwater lobster fry and support their survival. This research was carried out at the Agriculture, Livestock, and Fisheries Greenhouse, Muhammadiyah University of Parepare, using freshwater lobster fry from captive breeding. The research method used was a Completely Randomized Design (CRD) with four treatment doses of a combination of amino acids and dissolved glucose, namely: A) 100 ppm glucose + 250 ppm amino acids, B) 150 ppm glucose + 200 ppm amino acids, C) 200 ppm glucose + 150 ppm amino acids, and D) 250 ppm glucose + 100 ppm amino acids, each with three replications. The parameters explained are the chemical composition of the body, including protein, fat, fiber, and BETN content. A combination dose of 250 ppm glucose and 100 ppm amino acids is most effective in improving the nutritional quality of freshwater lobsters (Cherax quadricarinatus). The results of this study show the highest protein content (14.28%), fat content (0.89%), and fiber content (0.7%), all of which are important for the growth and health of lobsters. Meanwhile, the combined dose of 100 ppm glucose + 250 ppm amino acids yielded the best BETN (4.95%). Overall, the 250-ppm glucose and 100 ppm amino acid combination is optimal for improving the chemical composition of the lobster's body.
