Abstract

Teluk Benderas Lake is an oxbow lake formed because the Kampar River's flow was cut off. This lake is a habitat for various types of fish. However, information on fish species in the area is still limited. To find out the kinds of fish in Teluk Benderas Lake, a study was conducted in March-May 2023 using the survey method. Fish sampling was performed once a week for two months. The fish were caught using a trawl measuring 150 m long and 4,5 m wide with 1-inch mesh size. Water quality parameters measured were temperature, brightness, depth, pH, DO, and CO2. The results showed that 1.398 fish were caught, consisting of 4 orders, 13 families, 25 genera, and 32 species. Based on the results of water quality measurements, it was concluded that Teluk Benderas Lake can still support fish life in the waters.

Abstract

Pangasianodon hypophthalmus is a freshwater fish that can grow well in dark condition. In no light condition, fishes are more responsive to feed provided. However, phytoplankton may not grow well, and as a consequence the water quality was poor and it negatively effects the fish health in general. The combination of biofloc and photoperiod manipulation systems is expected to improve the water quality as well as the fish health. To understand health status of the fish in general, the histological structure gill, kidney and liver was investigated. Sample were fixed in 5% formalin, paraffin processed and Haematoxylin Eosin stained. There were 2 factor, 3 treatment applied, namely natural (control), 18G (18 hours dark), 24G (24 hours dark) and 3 repetition. Parameter measured were survival rate and histological structure of gill, kidney, intestine and liver. Results shown that there are not difference of histological structure of the organs of fish reared under biofloc and manipulated photoperiod systems. There were light abnormalities in the gill, such as hyperplasia, hypertrophy, oedema and necrosis. There is no negative effect of biofloc system and photoperiod manipulation in structure of fish organ as there is only light abnormalities that can be cured when the water quality is good.

Abstract

Luciocephalus pulcher lives in peat swamps, and the male incubates the eggs in the mouth. A study aimed to determine morphometric characters and differences in the oral structure of male and female fish was conducted from June to July 2024. Fish samples were caught in the upper Sibam River. 5 times, once/week. The morphometrical characteristics were measured, and the fish mouth structure was observed. Results showed that 32 fish were caught, consisting of 21 males and 11 females. Of the 37 morphometric characters observed, 18 differed between males and females. These characters included total length, head length, body height, caudal peduncle height, eye diameter, anal fin to caudal fin base distance, dorsal fin base length, pectoral fin base length, anal fin height, ventral fin base length, caudal fin base length, lower jaw length, upper jaw length, lower jaw width, gular sac width, lower lip length and upper lip length. The total length of male fish ranged from 48-135 mm, while females were 48-135 mm. Fin characteristics in male and female fish were the same, with the formula D.I, 8-12 P.12-15 V.6-7 A.I, 14-20 C.13-15. The difference in mouth characters was seen in the gular sac. The gular sac of male fish was wider with thicker tissue, more folded, more flexible, elastic skin tissue, and smaller, more flexible hyoid bone. In contrast, female fish have smaller, less elastic gular sacs, thinner tissue, and less folded and thicker hyoid bone.

Abstract

Penelitian ini bertujuan untuk mengetahui jenis-jenis udang yang berasosiasi dengan jenis mangrove yang ada pada perairan ekosistem mangrove Desa Apar, Kota Pariaman, Sumatera Barat. Penelitian ini dilaksanakan pada November-Desember 2023 di Kawasan Mangrove Desa Apar, Kota Pariaman, Provinsi Sumatera Barat. Penelitian ini menggunakan metode survei, dimana penangkapan sampel dilakukan di lokasi penelitian, dan diamati di laboratorium. Penentuan titik sampling menggunakan metode purposive sampling dan dilanjutkan dengan metode road sampling ke arah hulu selama 2 jam sejauh 500 m (Ratti & Garton, 1996). Penelitian ini dilakukan 30 menit pada masing-masing stasiun. Hasil dari penelitain ini diketahui ekosistem mangrove di Desa Apar telah teridentifikasi 4 jenis udang dimana keempat jenis udang tersebut memiliki klasifikasi yang sama pada tingkatan filum Arthropoda, kelas Malacostraca, ordo Decapoda dan berbeda mulai pada tingkatan famili Panaedae (udang windu/P. monodon), famili palaemonidae (udang galah/M. rosenbergi dan udang M. equidens), famili Alpheidae (udang pistol/Alpheus euphrosyne). Terdapat asosiasi positif antara udang dan jenis mangrove. Hal tersebut terjadi akibat adanya persamaan ekologi habitat serta kualitas air yang dibutuhkan pada masing-masing jenis udang dan mangrove.
