RESPON REPRODUKSI INDUK BETINA SEPAT SIAM Trichogaster pectoralis TERHADAP PENAMBAHAN BAHAN SUPLEMEN DAN IMBUHAN PAKAN
Get PDFThe problem of the breeding of the snakeskin gouramy management was theinsufficient maximum degree of hatching eggs which only reached 80.03 %. One of the ways to overcome the problem was to improve the quality of eggs through the improvement of quality of feed given to the mothers of snakeskin gouramy withsupplements and food additives. This study aimed to evaluate the reproductive response of female snakeskin gouramy against the addition of supplements and feed additive, suchas: fish oil, vitamin E and extracts of ginger. The tested fish was female snakeskin gouramy with a minimum age of 8 months and were at maturity level of TKG I or TKGII. The Food used in this study were 3 kinds of commercial feed with the addition of vegetable oil (FCO), the feed with the addition of fish oil and vitamin E (FOT) and the feed with the addition of fish oil, vitamin E and extracts of ginger (FOTG).The results showed that FOT and FOTG could produce gonadosomatic index (GSI), fecundity, egg diameter, hatching eggs and survival rate better than the FCO feed.This occured presumably because of the effect of the addition of vitamin E that prevent edoxidation of fatty acids, so that fat could be used completely. As a result, the quality and quantity of eggs increased. GSI value on all treatments ranged from 3.07 to 3.57 %,fecundity ranged between 3,875 to 5,355 grains, egg diameter ranged from 0.70 to 0.93mm, hatching ranged from 78.12 to 89.58 % and survival rate ranged between 51 to 83 % in all treatments. Food with the addition of fish oil and vitamin E could produce better diameter of eggs and survival rate, while feed with the addition of fish oil, vitamin E and extracts of ginger could generate value gonadosomatic index (GSI), fecundity and hatching eggs higher

EVALUASI PENGGUNAAN BAHAN KIMIA BERBAHAYA PADA PRODUK PERIKANAN DI KOTA MAKASSAR
Get PDFThis research aims to determine the use of hazardous chemicals in fishery products that are marketed in the city of Makassar. In this study used the Accidental Sampling Technique. Samples are taken from the center of Makassar souvenirs, traditional markets, and modern markets. The fishery products used as samples are crackers, meatballs, and brains. Hazardous chemicals evaluated for use are borax and formalin. The samples were analyzed using a test kit and colorimeter at the BIOCHEME Laboratory (Healthy Food) Department of Chemistry,University of Brawijaya. The results show that fish meatball products marketed in Makassar City do not contain borax, but contain formalin 11.2 - 13.13 ppm. Brain-brain products do not contain borax and do not contain formaldehyde, fish/shrimp crackers marketed in Makassar City do not contain formaldehyde but 33% contain borax with an average, level of 10.39 ppm
THE USE AND ECONOMIC VALUATION OF MANGROVE RESOURCE IN TONGKE-TONGKE MANGROVE AREA, SINJAI DISTRICT, SOUTH SULAWESI PROVINCE, INDONESIA
Get PDFThe research was The aim of the research was to carry out to the economic valuation and the use of mangrove resource Tongke-Tongke at the mangrove area Sinjai District, South Sulawesi, Indonesia. Survey research approach was used in this research and data were analyzed descriptively and quantitatively. The result showed that mangroves were utilized to capture fisheries and wood sources utilization. The economic value of mangrove was $USD 4,330.95 /ha/year. Capture fisheries are the largest contribution, up to 94,47 percent, while mangrove wood utilization 5,53 percent to be a most important income source for society in coast who live in the vicinity. Therefore, coastal management policy was required to be developed by considering the impact on the socioeconomics of mangrove utilization on the community at area coast, especially related to coastal utilization area change
