EEL (Anguilla bicolor bicolor) Rearing Techniques at the UPTD for Conservation and Supervision of Marine Fishery Resources of Sicincin, West Sumatra

Abstract

Eel has a savory meaty taste and contains high levels of Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA). The purpose of this observation was to determine intensive rearing techniques for eel (Anguilla bicolor bicolor) at the UPTD KPSDKP for Conservation and Supervision of Marine Fishery Resources of Sicincin, West Sumatra. The preparations conducted for rearing the eel consist of providing seeds, pond preparation, water supply, feed management, water quality control, disease control, growth sampling, and harvesting eel for consumption size. The eel seeds were obtained from natural catches of glass eel in the Cimandiri river, Pelabuan Ratu, West Java. Preparation of the eel pond included cleaning the concrete pond, filling the water by observing the water input into the eel pond. The provision of water for eel rearing was obtained directly from the Kapalo Ilalang Sicincin irrigation channel to the holding tanks before flowing to the eel rearing pond. Feeding management was carried out 2 times a day, namely the percentages of feeding in the morning (35 %) and at night (55%) with a feeding rate of 3%-5%. The feed provided to these eels was in the form of a paste made of powdery pellets. Measurements of water quality for eel rearing during observations were temperature (27-29°C), pH (6-7), DO (5.9-7.8 ppm), salinity (3-4 ppt) and NH3 (0.02-0.07 mg/l). In our observations, parasites shaped like cotton were discovered, which attacked the eel body, causing death. In growth sampling, the measurement of the length and body weight of the eel once a month is necessary to be done.

“…The results of temperature measurements at each station showed that the temperature ranged from 29-31°C. This is in accordance with the statement of [13] which states that the optimal temperature for the life of mud crabs is in the range of 25-35 °C. The results of salinity measurements at each station obtained salinity results ranging from 20-25‰.…”

“…The results of salinity measurements at each station obtained salinity results ranging from 20-25‰. This is in accordance with the statement of [13] which states that a good salinity for the life of mud crabs is 10-25‰. The pH measurement value at each station showed that the pH ranged from 7-8.…”

“…This is in accordance with the statement of Shelley and Lovatelli (2011) which states that a good pH for the life of mud crabs is 7.5-9.0. Good water quality supports the life of organisms [12][8] [13].…”
