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% .

Ikan kakap merah (L. gibbus) adalah jenis ikan demersal dari famili Lutjanidae yang bernilai ekonomis penting dan banyak tertangkap di Indonesia. Informasi tentang kebiasaan makan dan aspek reproduksi ikan kakap merah di Indonesia masih relatif sedikit. Selain itu, telah terjadi penurunan stok ikan kakap merah di Selatan Banten selama 6 tahun terakhir (2008-2013). Penelitian ini bertujuan untuk mengkaji hubungan panjang-berat, kebiasaan makan dan reproduksi ikan kakap merah.. Penelitian dilakukan selama 3 tahun (2013, 2015 dan 2016). Ikan contoh diambil dari hasil penangkapan ikan oleh para nelayan dengan alat tangkap pancing rawai dasar dan pancing ulur dengan mata pancing no 7-10 yang didaratkan di Binuangeun-Banten. Analisis fekunditas dilakukan di Laboratorium dengan metode gravimetrik. Hasil penelitian menunjukkan bahwa ikan kakap merah jantan memiliki ukuran lebih panjang dibandingkan ikan betina, pola pertumbuhannya bersifat isometrik. Kebiasaan makan ikan kakap merah tergolong ikan karnivora dimana makanan utamanya adalah ikan dan kepiting (Portunidae). Nisbah kelamin jantan dan betina tidak seimbang yaitu 1: 1.53. Fekunditas berkisar 14.050–596.243 butir dengan rata-rata 170 869 butir, diameter telur berkisar 0,03–1,02 mm dan pola pemijahannya bersifat salin sebagian (partial spawner).The humpback red snapper (Lutjanus gibbus) is the family of lutjanidae which has important economic value in Indonesian capture fisheries. In addition, there has been a sharp decline on the population of  humpback red snapper in the Southern part of Banten during the last 6 years (2008-2013). This study aims to examine the growth function, food habits and reproductive biology of L. gibbus in the Southern part of  Banten Waters. Fish samples were collected for 3 years (2013, 2015 and 2016) both from fishing ground and landing places in Binuangeun-Banten, caught by handline and bottom longline. The fecundity analysis was performed in Laboratory by gravimetric method. The results showed that the average size of males of humpback red snapper was longer than females with the growth pattern was isometric. The food habits of humpback red snapper was classified as carnivorous fish in which the main food item consist of fish and crab (Portunidae). Sex ratio of males and females were unbalance by 1: 1.53. The fecundity ranges from 14.050-596.243 eggs with an average of 170.869 eggs. The humpback red snapper found as  partial spawner which eggs diameter ranged from 0,03 to 1,02 mm.

Length-weight relationship (LWR), condition factor (K) and feeding habits of Coilia dussumieri, Nemapteryx nenga and Nibea soldado from Santubong Estuary, Sarawak, Malaysia were reported in the present study. The sampling was conducted during the non-monsoon season and monsoon season from April to November 2017 at Buntal, Penambir and Demak rivers using three-layered gillnets. A total of 182 fish samples were caught and measured for the total length and body weight. Then, the data were analysed by the equations for LWR and K. The feeding behaviour analysis was carried out using Relative Gut Index (RGI) and Frequency of Food Occurrence method. The log-transformed regression showed that most of the fishes exhibited negative allometric. K showed a significant difference between seasons. The RGI values of the fishes showed that they were carnivorous. The highest frequency of food occurrence in both seasons was gastropods (94-95 %) and the food items were found to be more variable during monsoon season (gastropods insect, worms, fish, asteroidea, phytoplankton and bivalve). The b value is an exponent to measure the growth pattern of fish and in this study, the b values were in the expected range of 2.5-3.5 and not affected by seasonal variation. The K values suggesting that most of the species were surviving well in the river and was influenced by seasonal change. The RGI and frequency of food occurrence showed that all fish in this study species were carnivorous with more variability in food was observed during the monsoon season. The data of this study are important for a sustainable fisheries management in this area.

Fish found in natural tropical and sub-tropical water system experience frequent growth fluctuations. The study was conducted to determine the length-weight relationship and condition factor of Clariid species (Clarias gariepinus, Heterobranchus longifilis and Synodontis clarias) in Kano state of Nigeria. About 177 fish samples were collected from six rivers (Thomas, Ghari, Tiga, Duddurun-Gaya, Karaye and Bagwai) across the length and breadth of Kano state. Body weight (BW=248.48g), total length (TL=32.74cm) and standard length (SL=26.16cm) were determined. The length-weight relationship and condition factors were also determined. The condition factors showed varying degree of well-being of fish sampled from their habitat, and ranged from K = 0.37 to 0.89. The equation for the lengthweight relationship for the three strains is: C. gariepinus = -329.86+17.56TL, H. longifilis = -241.49+14.28TL and C. clarias = -428.51+22.72TL. Body weight and length had positive and significant relationship (r = 0.73 TL; r = 0.75 SL).
