Abstract

Studies on Rasbora sp. have been developed in the last two decades, but nostudy have been conducted on the fish spawning related to requirement of adomesticated fish (normal movement, feed on artificial food, growth, and spawn).An experiment on the ethology of R. latestriata executed in the concrete tank of3mx2mx15m watered continuously up to 50 cm in depth and by inlet pipe positionthe water move at the flow speed less than 10 cm/sec. More than 60 randomly maleand female fishes feed ‘ad libitum’ with catfish pellet artificial food and cultured forthree months in the rainy season. At the third month approximately hundred fishlarvae of 1 to 1.5 cm were found. This study concluded that Rasbora can be culturedcommercially, as the fish domesticated as ob-served moving normally, feedingartificial food, growth and spawn in the human control environment. However,further study on breeding and commercial aquaculture of the fish is necessary.

Abstract

The research was conducted for 60 days from April to June 2017. The aim of this research was to know the utilization of fermented leucaena leaves meal as a substitution of soybean meal in the diets on the growth and feed efficiency of Thai Catfish. Completely randomized design (CRD) was used in this experiment, with one factor, five level treatment and three replications. Fish were reared in 1 m3cages with stocking density 20/cages. Feeding trial were replacing soybean meal with fermented leucaena leaves meal applied to P1 (0%), P2 (25%), P3 (50%), P4 (75%), and P5 (100%). The fish used in this research with 2,13 ± 0,39g of weight. The result of this research showed that fermented leucaena leaves meal has significant effect (P>0,05) on growth and feed efficiency of Thai Catfish. Diets which contains 75% of fermented leucaena leaves meal and 25% of soybean meal (P4) produce the highest specific growth rate (4,11%/day), feed efficiency (62,6%), feed digestibility (59,45%), and protein retention (18,85%). Based on the result of this study conclude that fermented leucaena leaves meal can be used as substitution for soybean meal in diets of Thai Catfish.

Abstract

Sixty seven specimens of the young catfish Pangasius sutchi were divided into three groups. The group (A) was young catfish with size (Body Length, BL±STDEV) 5.6±0.4 cm, n = 24, group (B) was 9.4±0.5 cm, n = 24, and group (C) was 15.0±0.9 cm, n = 19. All specimens were forced to swim in swimming channel of the flume tank for examined their swimming performance. The result show that the swimming speed has negative correlation on the swimming endurance. Higher swimming speed will be at lower swimming endurance for three groups of the young catfish. The bigger young catfish had higher swimming performance than smaller. Based on estimation of the burst swimming speed was 86.8 cm sec-1 for group C, 74.4 cm sec-1 for group B, and 57.5 cm sec-1 for group A. The estimation of the maximum sustained swimming speed was higher for bigger than smaller fish, as 10.9 cm sec-1 for group A, 19.7 cm sec-1 for group B and 16.4 cm sec-1 for group C. The relationship between swimming speed and swimming endurance of the young catfish are discussed in detail in this paper.

Abstract

The Media is a material consisting of a mixture of nutrients used by microorganisms to grow and breed. Molasses and liquid waste know one of the alternative media which has the least inexpensive carbon source and is easily obtained from the waste food industry that is rich in nutrients and minerals, so it has the potential for bacterial growth of Bacillus cereus. The consetration of molasses used for growth medium is 1%; 1.5%; and 2% while liquid waste knows 8%, 10%, and 12%. Cell growth is measured by the method of Spectrophotometry, total plate count (TPC) and biomass while the incubation period of cell growth is measured every 0, 6, 12, 18, and 24 hours. The results showed from the molasses + skim milk and the tofu liquid waste + skim milk, the best medium of bacterial cell growth of B. cereus is a liquid waste know isolates K 12%. While the best growth concentrations molasses Medium bacterial B.cereus was N2% and K2%.
