Abstract

The research was conducted for 56 days from March to April 2015. The aim of this research was to find out respons of Catfish (Pangasius pangasius) fingerling on use of fermented is the diets. Four isonitrogenous (35% crude protein) experimental diets was formulated to contain 0, 20, 30, and 40% Fermented Rubber seed and 100, 80, 70, and 60% soybean meal (A, B, C, D, respectively). Completely randomized design (CRD) was used in this experimentThe result showed that a diet containing 40% Fermented Rubber seed and 60% soybean meal (D) support a good specific growth rate (3.03%/day), feed efficiency (31.63%,) and protein retention (26.31%.). Survival rate of fish was high (100%). It this concluded that up to 60% soybean meal can be substituted Fermented Rubber seed in the diets for freshwater catfishKey word: Diets, Fermented Rubber seed, Growth, Utilization, Pangasius pangasius

Abstract

Helostoma temmincki is a type of fish that inhabit swamp area in Riau. A study aims to understand the stomach content and its relation with size, sex and level of maturity of that fish has been conducted on February to May 2015. Fish samples were captured using gill nets, fish trap and line fishing. Stomach content of the fish was analyzed and it was used as a basis to calculate the Preponderance Index (PI).Total, there were 104 fishes captured, but 27 of them had empty stomach and could not be used for stomach content analysis. The number of fish analysed was 77. Parameters measured were Index of Preponderance (IP), type of food, total length, sex and gonad maturity level. Results shown that the main food of the fish is Bacillariophyceae (45,32%). The small fishes (61-86 mm TL) consume phytoplankton, while the big fish (90-165 mm TL) consume phytoplankton and zooplankton. The male and female’s stomach content was almost the same. Fish with relatively low maturity level eat mainly on phytoplankton, while mature fish consume phytoplankton and zooplankton. Based on data obtained, it can be concluded that the food of H. temmincki was various, and it is related to body size and gonad maturity level.Keyword: Helostoma temmincki, Swamp, Stomach Content Analysis, Index of Preponderance

Abstract

This research was conducted in March 2015 to find out the structure of  diatom community and the distribution of abundance planktonic diatom in coastal around Dumai City. The survey method was applied in four stations with different characteristics, each stasiun consisted three sampling strata. The total of diatomwere 10 genera namely:Eucampia, Leptocylindrus, Guinardia, Rhizosolenia, Melosira, Coscinodiscus, Thalassiothrix, Rhabdonema, Nizschia, and Bacillaria. The most genera that commonly found was Rhizosoleniabecause yhis genera was being able to compete better than other genera. Base on the formulation of diversity index (H'), dominance index (D), and equability index (E), explained that the structure of diatomplanktonic community in all stations were in a state of balance. It  means there was not competition both places and food. The result of ANOVA test gained that the distribution of the diatom abundance was not significantly different among stations.   Key Words: abundance, diatom planktonic, Dumai

Abstract

Salo River is one of the Kampar River’s tributaries. Several activities conducted along the river produced pollutant that affects the water quality of the river in general. A research aims to understand the water condition in the Salo River based on physical-chemical parameters was conducted from April to May 2015. There were three stations (St1, St2 and St3) and water samples were taken once/week for a 4 weeks period. Water quality parameters measured were current speed, depths, temperature, transparency, turbidity, pH, DO , CO2, BOD5, nitrate and phosphate content. Results shown that the current speed was 17.5-38 cm/second, depths 29-36.3 cm, temperature 28-28.5 ºC, turbidity 3.34-5.36 FTU, pH 5, DO 6.89- 8.23 mg/L, CO2 7.99-8.99 mg/L, BOD5 2.39-7.29 mg/L, nitrate : 0.0275-0.0555 mg/L, and phosphate 0.0375-0.0525 mg/L. Nitrate and phosphate concentration indicate that the Salo River is in oligotrophic condition.Keywords : Salo River, Water Quality, oligotrophic
