Abstract

Nowadays, geso fish Hemibagrus wyckii Bagridae is extinction The objective of this research is to analyze the distribution of length and weight of Geso fish, water quality parameter as the characteristic of Geso habitat and reproduction aspect which is the basic data to perform the domestication process. To know the distribution of length and weight of Geso fish, the samples were taken from three research locations, namely Kampar Kanan River, Kampar Kiri River and Koto Panjang Reservoir, each with 15 individual, To analyze the reproduction aspect of Geso fish required 45 samples and to get the data of Geso fish habitat characteristic was taken once monthly water samples in June, July and August 2015 in three research sites, Kampar Kanan River, Kampar Kiri River and Koto Panjang Reservoir. The results showed that the average length of total and weight of geso fish from Kampar Kanan River (491.93 mm, 1390.83g) and Kampar Kiri River (489.73 mm, 1338.97g) was higher than that of Koto Reservoir Length (286.60 mm; 1078 g). The water quality parameters that are the main differentiator between the three habitats are nitrite, nitrate, electric conductivity and COD. Fecundity of geso fish ranges from 2943-9558 eggs with egg diameter ranging from 1.04 to 2.81 mm. Gonad Somatik Index (IGS) of geso female fishingTKG IV between 2.73-3.97%and males between 1.22-2.00%.

Abstract

The purpose of study is to know nutrition of jelawat eggs, compriseprorein, fat, calcium, phospore, essential amino acid, essential fatty acid, vitamineC and vitamine E. Method applied to get the purpose is take jelawat eggshave TKG IV ( gonad stages mature) on brood stock with 4kg, and weight wet ofgonad 600 gram at Maninjau Lake. Eggs are dried and floured. The study usesproximate-analysis to get quantity of protein, fat, calcium and phospore andHPLC methode to get the essential amino acid, fatty acid and vitamine C and E.The result show that fish jelawat floured have within it nutrition protein61,33 %, fat, 11,90 %, water content 4,88 %, ashes content 8,26 %. Quantityamino acid 52,69 %, linoleat fatty acid 7,71.%, linolenat fatty acid 0,05 %,vitamine C 0,240 % and vitamine E 0,310 %.
