Chemical composition of whiteleg shrimp (Litopenaeus vannamei) cultivated from intensive farming and traditional farming at Bulukumba regency, South Sulawesi

Abstract

The aim of this research was to study the effect of intensive and traditional farming on the chemical composition of whiteleg shrimp (Penaeusvannamei) during storage till up to 8 days. The study on intensive and traditional farming were done at MariorennuVillage, Gantarang Subdistrict and at Manjalling Village, Ujung Loe Subdistrict, respectively, Bulukumba Regency, as well as at the Research and Development Center of Fishery Products of Makassar, South Sulawesi, the Province of South Sulawesi. The research design was conducted by a randomized complete block design with a storage treatment of 0, 2, 4, 6, and 8 days. The parameters studied are water content, ash, lipid, and protein content, as well as total volatile base (TVB), trimethylamine (TMA), pH, and free fatty acids (FFA). Whiteleg shrimps from intensive farming and traditional farming were stored in a coolbox containing with 2: 1 ratio of ice and shrimp, respectively. The addition of ice was carried out every day for 8 days storage, and chemical analysis was condcuted at intervals of 2 days. Chemical testings was carried out based on the SNI method. Samples were measured as much as 10-15g and then chemically tested reffer to the method in SNI. The results for both intensive and traditional farming of whiteleg shrimp showed that storage time had a significant influence on the following parameters i.e. TVB, pH, FFA, water content, and protein content. No significant effect was found for following parameters, namely TMA, ash and fat content.
