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

Puntius schawanefeldii is one of common fish in the Koto Panjang Dam. This fish commonly present around the floating cage culture area. Small P. schawanefeldii sometimes enter the culture cages and become trapped in the cages as they grew up. Farmers used to remove the trapped fish and put them in the cage around the cage culture area. The net caged P. schawanefeldii were not given any food, but they were able to grow. To understand the feed consumed by the caged fish and compare it with the free living fish, a study on the stomach content analysis of the caged and free living fish has been conducted on September 2022. Samplings were conducted 2 times, once/2 weeks and the stomach contents was analyzed using a volumetric method. There were 139 fishes captured. The stomach 104 fishes were full or partly full, while the stomach content of other 35 fishes were less than 25% and could not be analyzed. Results shown the stomach content of the caged and free living fish were similar, there were algae and pellets (they could not be separated), fish feed pellet remains and fish tissue remains. The Preponderance Index of each food type present in the caged fish are pellets 71.24%, mixed algae and pellets 26.76%  and fish tissue remains 2.00%, while those of the free living fish are  pellets 16.28%, mixed  algae and pellets 70.63%, and fish tissue remains 11.44%. Data obtained in this research indicate that the caged fish receive fish feed pellets that spilled out from the culture floating nets in the surrounding area.

Abstract

Strombus turturella is a type of gastropods that live in the shallow coastal area of the Dompak Island. A research aims to understand the morphometrical, meristical characteristics and growth patterns of S. turturella from the Dompak Island was conducted in June-July 2018. The number of snail sampled was 400, with 46.98-83.07 TL mm and 13-46 grams BW. There were six morphological characteristics measured, there were total length, shell length, aperture length, shell width, shell depth and lip thickness, and there was one meristical characteristic count, namely the number of spire. Results shown that there are 5 morphometrical characteristic differences in males and females. Total length of male is longer than that of the female. While other characteristics, such as the shell length and aperture of the females were longer, the shell was wider, deeper and the lip was thicker than those of the males. The number of spire was 4-9 in males and 4-8 in females. The lengh-weight relationship shown that the growth of males and females is allometric negative (b=0.503).
