Abstract

Research about the food habits and feeding habits of Barramundi (Lates calcarifer Block) in Terusan Dalam (inside canal) waters, East coast of South Sumatera Province, had been done during March to June 2012. The purpose of this research was to analyze the food habits and feeding habits of  Barramundi (Lates calcarifer Block) on Terusan Dalam (inside canal) waters, East coast of South Sumatera Province. Sampling method of the fish was purposive sampling method using Tangsi net. The results of this research showed that the number of fish from March to June totaled 31 individuals of fish. Based on the Relative Importance Index (RII), the natural food of Barramundi (Lates calcarifer Block) in March to June 2012 consisted of shrimp as the main food with the Relative Importance Index 72.37-99.51%, the fish was as the complement food with the Relative Importance Index 11.33-27.63%, and as the additional food was the worm with Relative Importance Index 0.49%.Keywords: Barramundi, food habits, feeding habits

Abstract

The research about food habits of Lundu fish (Mystus gulio Hamilton, 1822) in the waters of Sungai Dua (Two Rivers) Village, Rambutan District, Banyuasin Regency, South Sumatra. The sampling was conducted in five times in December 2016; January, February, March and April 2017. Identification of the samples was in Laboratory of Animal Taxonomy, Biology Department, Faculty of Mathematics and Natural Sciences, Sriwijaya University, Indralaya.The purpose of the research was to analyze the food habits of Mystus gulio Hamilton, determine the relationship of length-weight, determine the conditions, analyze the gastric fullness index. The results of this research showed that the food habits of Mystus gulio Hamilton is plankton, like Cyanophyta, Chlorophyta, Diatomae, Desmidiacae, Euglenophyta, Pyrrophyta, Ciliata, Rhizopoda, Rotaria, and Entomostraca.

Abstract

The Sumatran Striped Rabbit (Nesolagus netscheri ) is  a naturally rare, which is a protected animal based on Government Regulation Number 7 of 1999 and renewal of Permen LHK No. P.106 which are categorized as Data Deficient  by the IUCN (International Union of Conservation of Nature) since 2019. Samples were obtained from Pagar Alam, South Sumatra. Most commonly found at elevations  above 600 m in montane and sub-montane primary habitat. Molecular genetic characterization of sumatran striped rabbit is to know genetic information and genetic identification of N. netscheri. Primers 12S rRNA were used in this study to characterize Sumatran striped rabbit. A 1 band were detected ranged from 900 to 1000 bp. Molecular markers represent reliable tools which may have a great impact in rabbit breeding and genetic improvement of rabbits. Molecular markers on Nesolagus netscheri is expected to tools in the identification of Sumatran striped rabbits from South Sumatra.

Abstract

The initial phase of the fish life cycle is a critical phase associated with high mortality due to sensitivity to predators, food availability, and also environmental changes that occur in nature. Disruption of the initial stages of fish life has a negative impact on fish populations. Until now there has been no information about fish larvae around the Banyuasin River Estuary. Therefore, research is needed on the diversity of fish larvae around the Banyuasin River Estuary, South Sumatra Province. This research were used purposive sampling method, sampling technique in the form of Cruise Track Design with continuous parallel survey trajectory. Based on the results of the study found as many as 10 families consisting of 1483 individuals of fish larvae in March and 1013 individuals of fish larvae in May consisting of Engraulidae 1,601 individuals of fish larvae, Mungiloidei as many as 109 individuals, Leiognathidae 50 individuals, Chanidae 453 individuals, Scatophagidae 20 individuals , Belonidae 39 individuals, Gobioididae 5 individuals, Chandidae 183 individuals, Syngnatihidae 6 individuals, and Gobiidae 30 individuals fish larvae. The index value of fish larvae diversity is classified as medium category (March 1.02 and May 1.12), Morisita index shows the distribution pattern of fish larvae classified as a group (March 0-14.17 and May 2.43-10.40 ), and the evenness index value is in the medium category (March 0.437 and May 0.521).
THREE SPOT GOURAMI (Trichogaster trichopterus) FOOD HABITS IN THE KOMERING RIVER'S DOWNSTREAM, SOUTH SUMATERA Ridho, Moh. Rasyid; Patriono, Enggar; Junaidi, Endri; Avesena, Muhammad; Karolina, Anita; Ardelia, Vera

Abstract

One of the downstream areas of the Komering River with potential for capture fisheries is Sungai Dua Village. One of the types of fish caught by fishermen in Sungai Dua is the three spot gourami (Trichogaster trichopterus). The three spot gourami fish is a type of freshwater consumption fish that has high economic value. But the fishes only rely on catches from nature. If the fishing is carried out continuously, without domestication and cultivation, it will cause a decline in the fish population. The research about the biological aspects of red-eye septic fish (Trichogaster trichopterus) which include food habits, relationship length and weight, condition factors and stomach fullness index. This research was conducted from April to June 2017. Sampling was carried out in the downstream waters of the Komering River in Sungai Dua Village, Banyuasin Regency, South Sumatra. Fish samples were analyzed at the Animal Taxonomy Laboratory, Department of Biology, Faculty of Mathematics and Science, Sriwijaya University. The determination of stations in sampling was carried out using multiple sampling methods, namely purposive sampling and quota sampling. The result of this research showed that (1) the Cyanophyta is the main food for the three spot gourami, Diatomae and Desmidiacae as a complementary food, while the additional foods are Rhizopoda, Chlorophyta, Ostracoda, and Entomostraca, (2) The growth pattern of red-eyed fish is negative allometric with a b value of -2 (b <3), the increase in length is faster than the weight gain, (3) The highest condition factor value is found in the size range 6.01-7.00 cm of 23.25 gr / cm and the lowest condition factor value is in the size range 5.01-6.00 cm of 0.62 gr / cm, and (4) The highest hull fullness index value of the red eye sepat fish hull is in the size range 7.01-8.00 cm at 32.86% and the lowest hull fullness index value at the size range 8.01-9.00 cm is 2.05% .
