“…Hal ini sesuai dengan pernyataan Alviodinasyari et al (2019), bahwa ikan gabus betina cenderung lebih besar dibanding ikan gabus jantan, sehingga kepala ikan gabus betina relatif lebih lebar dibandingkan dengan ikan gabus jantan. Menurut Muslim (2019), ciri-ciri yang membedakan jantan dengan betina dapat dilihat dari kepalanya, ikan gabus betina cenderung memiliki bentuk kepala yang membulat sedangkan ikan gabus jantan cenderung memilki bentuk kepala yang lonjong.…”

“…Hasil rata-rata rasio ikan gabus pada jarak C5, bahwa ikan gabus jantan memiliki nilai rata-rata rasio yaitu 0,381±0,016, sedangkan nilai rata-rata rasio ikan gabus betina yaitu 0,393±0,016, dengan nilai asymp.sig 0,021. Hal ini menunjukkan ukuran badan bagian belakang ikan gabus betina secara diagonal dari titik awal sirip anal hingga akhir sirip dorsal lebih besar dibandingkan ukuran ikan gabus jantan, hal ini sesuai dengan pendapat Muslim (2019), bahwa ikan gabus betina memiliki perut yang lembek dan membesar dari pada perut ikan gabus jantan. Nilai yang signifikan pada jarak C5 terdapat perbedaan dengan hasil penelitian Muslimin et al (2020), karakter truss dari bagian badan belakang yang dapat digunakan untuk membedakan jenis kelamin ikan gabus, yaitu C3 yang merupakan jarak dari akhir sirip dorsal hingga akhir sirip anal.…”

The increase in the high demand for snakehead fish from the community causes high exploitation of this fish. The high activity of catching snakehead fish along with the production volume that increases every year will certainly threaten the sustainability of snakehead fish. The need for morphometric and meristic research is to provide information that can be used for conservation efforts in the Klawing River. The purpose of this study was to determine whether standard morphometry, truss morphometric, and meristic can be used to identify the sex of snakehead fish from the Klawing River and to determine the specific characters that distinguish the morphology of male and female snakehead fish. The method used is a survey with accidental sampling from the Klawing River assisted by fishermen. Sampling was carried out 5 times from February to March 2021. The variables observed were morphological performance, standard morphometry, truss morphometric, and meristic. Parameters in this study were body shape, mouth shape, mouth position, caudal fin shape, type of scales, tooth type, ratio of body parts distances, number of fin rays, and number of scales. The perfprmance morphological, standard morphometric, truss morphometric, and meristic then analyzed descriptive. The results showed that morphological performance could not be used as a sex determine of snakehead fish. The standard morphometric characters that can be used as sex differences for snakehead fish from 21 characters are head width with an asymp.sig value 0.20. The truss morphometric character that can be used as sex distinguishing snakehead fish is from 23 characters, A1 with an asymp.sig value 0.048, A6 with an asymp.sig value 0.038, C5 with an asymp.sig value 0.021. Meristic characters cannot be used to distinguish the sex of snakehead fish, because they have relatively the same number of fin rays and scales.

“…Domestikasi ikan gabus (Channa sp.) telah berhasil dilakukan oleh peneliti-peneliti di Indonesia (Ndobe et al, 2014;Muslim, 2019;Saputra dan Mahendra, 2019). Meskipun domestikasi ikan gabus lokal telah berhasil dilakukan, namun masih banyak permasalahan yang dihadapi dalam mendomestikasi ikan gabus lokal.…”

Snakehead fish (Channa sp.) is one of Indonesia's native freshwater commodities that has been successfully domesticated by fish farmers, yet the domesticated snakehead fish culture still has problems, namely the low survival and growth of local snakehead fish. Overcoming this problem requires a technology that can optimize the survival and growth of the domesticated snakehead fish (Channa sp.). One technology that can be applied is the use of probiotics. This reserach aimed to examine different probiotics through feed to optimize the survival and growth of domesticated snakehead fish (Channa sp.). This research was conducted with an experimental method. The experimental design used was a completely randomized design with 4 treatments and 3 replications. The treatments were control treatment (P0), treatment with probiotic composition of Lactobacillus sp., Bacillus spp. and Nitrosomonas sp. (P1), treatment with probiotic composition of Lactobacillus casei and Saccharomyces cerevisiae (P2), and treatment with probiotic composition of Lactobacillus sp., Acetobacter, Rhodobacter sp., yeast (P3). The results showed that different probiotic feeding had a significant effect (P<0.05) on the survival parameters and different probiotic feeding compositions had no significant effect (P>0.05) on the growth parameters. The composition of Lactobacillus casei and Saccharomyces cerevisiae probiotics is the best probiotic composition to increase survival and growth of domesticated snakehead fish.Keywords: Domestication, Growth, Survival Rate, Probiotic

“…Teluk Gelam lake is a lake water and is located in a swamp forest environment (rawa lebak). According to [23], in a condition of lack of water, the snakehead fish is still able to survive because the snakehead fish has a breathing apparatus so that it can utilize the free oxygen in the air for its breathing process.…”

This study aimed to analyze the quality of the waters and its relationship with the structure of phytoplankton communities and fish resources. This research was conducted in March 2021 at lake Teluk Gelam Ogan Komering Ilir. Phytoplankton sampling has been done once with 3 replays and there are 5 station points. Measurement of water quality parameters physical and chemical waters include temperature, pH, dissolved oxygen (DO), ammonia, brightness, turbidity, depth, nitrite, nitrate, and phosphate. Water quality analysis was calculated using the pollution index method (IP) and evaluated based on environmental quality standards according to the Decree of the State Minister for the Environment Number 115 of 2003. Based on the results of research that have been conducted in the lake Teluk Gelam district Ogan Komering Ilir that the overall average parameters of water quality in the lake were still an adequate condition for the life of organisms, especially phytoplankton. And based on the observations on the composition of phytoplankton structures in the waters of the lake Teluk Gelam found 3 classes of phytoplankton consisting of Bacillariophyceae, Chlorophyceae, and Cyanophyceae with a varied number of genera, while the fertility level of Teluk Gelam lake waters is included in the eutrophic category.
