Abstract

When migrating to the deep sea, the eye of the eel which functions for locomotion will adapt to the deep environment. This study is the first study to identify the locomotion index and the retinal structure at the stage glass eel, elver, yellow, and silver eel Anguilla bicolor bicolor. Character and habitat information for each stage of eel can be used as a conservation strategy. Seventeen eel fish samples were collected from the Pasir Puncu River in Purworejo. Observation of the Locomotion Index is done by comparing the Eye Index (EI), Pectoral Fin Index (PFI), Anal Fin Index (AFI), and Dorsal Fin Index (DFI) at several stages of development of eel, while histologically the observations were carried out with analyzing the retina structure and the thickness of Rod and Cone Layer (RCL), Outer Nuclear Layer (ONL), Inner Nuclear Layer (INL), Ganglion Layer (GL) and Nerve Fiber Layer (NFL). Based on these observations it can be seen that the retina (RC, ONL, INL, GL, NFL) will have increased from yellow to the silver stage, this is due to adaptation eels that adapt to new habitats. The locomotion index shows that the more developed the pectoral fins, the greater the thickness of the NFL, which indicates the greater the number of nerves used for adaptation in the ocean. In the early elver stage, eels tend to swim on the surface of the water in brackish waters. At the yellow eel stage, the eels have started swimming on the bottom of the water that is rich in the substrate with darker environmental characteristics, while at the silver stage, the eel will begin to adjust to the darker deep sea.

Abstract

Catfish is a highly favored source of protein in Indonesia. Catfish farming can be carried out using various types of feed and methods. This research aims to determine the effect of two types of fish feed with high (24%) and low (4%) protein content on several aspects of catfish cultivated using the pond/bucket culture method. The methods include catfish maintenance, physicochemical measurement, morphometric measurements, survival rate measurements, proximate testing, and histological preparations of catfish intestines and stomach. The results show that the TDS and pH values in the high-protein feed are higher than in the low-protein feed, while the temperature fluctuates. At the end of the observation, there is a significant difference in the morphometry of catfish fed with high-protein feed, where the body weight, head width, and body length are higher. The difference in body weight of catfish fed with high-protein feed is significantly higher (119.58±16.72 g) compared to those fed with low-protein feed (52.20±4.80 g). The average number of surviving catfish fed with high-protein feed is lower (27.60±8.23 fish) compared to the other group (44.00±2.55 fish). Proximate testing indicates that catfish meat with high-protein feed also has higher protein, fat, and carbohydrate content. Histological analysis shows that catfish with high-protein feed have longer villi and higher number of goblet cells, while the length of the gastric pits is lower. This research demonstrates that high-protein feed has an impact on fish quality, while ensuring water quality to reduce catfish mortality rates in catfish pond culture.
