Opudi fish (Telmatherina prognatha) is an endemic fish that live in the Lake Matano. Growth pattern of Telmatherina prognatha is very important to be studied for species conservation and management effort. This study aimed to analyze size distribution, growth pattern and condition factors of the fish as a basic information for fish resources management at Lake Matano. The study was conducted from March to August 2018 on six sampling locations. The fish sampling was carried out using multifilament nets with 0.5 inches in mesh size (30 m length and 2 m width) in the lake. The caught fishes were measured for total length and weight for growth analysis. The total of fish (n=853 individuals) consisted of male (483 individuals) and female (370 individuals). Total length (TL) of the fish ranged between 36.46-64.09 mm (mean 51.73±4,74mm) for male and 32.93-66.20 mm (mean 49.81±5.31 mm) for female fish. The growth patterns (length-weight relationships) of male and female fish were W=0.0004L­2,5995 and W=0.0006L2,4875, indicating negative allometric growth patterns, respectively. Range condition factors in average were various and 0.9864±0.2084 in average for male and 1.0121±0.1571 for female, respectively, with quite high values on June 2018.

Swamp eel (Monopterus albus) is an economically important freshwater fish which has the potential to sustainable development. This species is considered as one of the taxonomically problematic spesies due to its complex characters and similar morphology to Monopterus cuchia and Monopterus javanensis that often lead to taxonomic dilemmas. Taxonomic certainty is an essential basis information in sustainable fisheries management, studies on morphometric characters, and genetic variability is a method which commonly used for species or stock identification. This study was aimed to validate the taxonomy certainty and evaluate the kinship of swamp eel from four populations (Indramayu, Subang, Tasikmalaya, and Garut distrik) in West Java. Morphometric analysis was conducted by measurement of 19 characters, whereas genetic analysis was conducted using PCR-Sequencing method of COI gene. The results from stepwise discriminant analysis showed that 7 morphometric characters ratio were powerful to classified the populations and the first two discriminant functions accounted 84.2% of the total variability. Genetic diversity indicated by alignment 14 sekuen of COI gene showed there were 11 haplotypes from 109 variable sites. Results of cluster and phylogenetic tree analysis indicated that swamp eel from four research populations were grouped into two major clusters. The first cluster consists of Indramayu and Subang population, the second cluster consists of Tasikmalaya and Garut population. This cluster is an evidence that swamp eel from West Java possesed morphometric and genetic diversity among populations and lead to assumption that at least there were two cryptic species from M. albus in West Java.

Snakehead fish (Channa striata) is one of fish species that lives in the flooding swamp area. The flooding swamp area is a shallow waters located in swampy forest area, has water temperature of 28-32°C, pH 3-4, and low oxygen content (2-4 mg/L). This study aimed to examine the pattern of reproduction in snakehead (Channa striata) in the area of flood swamp water. This study was conducted for 6 months from August 2016-January 2017. Samplings of fish were taken from upstream, middle, and downstream of Sebangau river in Central Borneo. Measurements of total length and body weight were carried out on 545 samples of the fish. The results of the research showed that the length growth of the fish was not as fast as the weight growth, the sex ratio of fish in gonads mature was 0.6:1.0 (male:female). The size of body length at the first gonad maturity in female snakehead was 27.75 cm and the male fish was 32.17 cm. The spawning season of snakehead fish took place from August to October and peak in October. Spawning of experimental fish was located in the downstream (station 3). Snakehead fish is a total spawner. Snakehead fish has a large reproductive potential with fecundity ranging from 55341 to 65507 eggs. Keywords: floodplain area, reproductive biology, snakehead

Chromium is a risk pollutant through their carcinogenic character non degradable by organisms and accumulate into the environment. The aims to find LC50-96h of chromium on test organism. The test organism used are Oreochromis niloticus, these organisms may represent the actual condition of the environment. This study was divided into 2 steps i.e. basic and lethal toxicity (LC50-96 h) tests, being run in triplicates. Lethal toxicity test data were probity analyzed. The result showed that LC50-96h of Cr6+ on Oreochromis niloticus was 61.2 ppm.

Today, eel resource especially seeds in Indonesia has not been used for eel culture activities. To be able to optimally utilize the seeds that led to the production of eels for consumption needs adequate cultivation technology. This study aimed to obtain performance information of survival rate, growth rate, and feed conversion ratio to support mass production of eel consumption. The experiments were performed using aquarium of (0.8 x 0.4 x 0.4) m3 and concrete tank (1.7 x 1.7 x 1) m3with circulating water. Eel used were elver (1.2-1.5 g) and fingerlings (15-17 g). Silk worms (Tubifex) and artificial feed in the pasta form were used as feed. The results showed that the elver reared in aquarium or concrete tank with water recirculation system showed high survival rate of 78-79% and 86-96%, respectively. The specific growth rate (SGR) was good (0.6-0.8%), but the feed conversion was still high (33-21) for the elver fed with silk worms and very good (0.6-0.7) for elver fed with artificial feed. The juvenile eel reared in a concrete tank showed SR up to 85-94%, the SGR ranged from 0.8 to 1.2%, and feed conversion from 0.61 to 0.69. It can be concluded that the rearing of seed eel can be done incontainer using water recirculation system with stocking density of 3 individuals/land 1.5 kg/m3in preparing the seed to be ready tobe cultivated outdoors.
