Abstract
Intensive culture of snakehead fish used artificial feed with high protein content. The impact of the high use of artificial feed will cause waste that can cause poor water quality and cause fish mortality. The purpose of this research was to know the dynamics of water quality during culture of snakehead fish Channa striata in the aquarium. The test animals used were snakehead fish with a length of 6.90 ± 0.49 cm and weight of 2.57 ± 0.59 g. Fish was maintenanced with a density of 2 fish L-1, 4 fish L-1 and 6 fish L-1. Fish was cultured for four days in an aquarium with size of 60x40x40 cm3 and water volume of 20 L. Water quality were observed, i.e, temperature, pH, dissolved oxygen, TAN, nitrite, nitrate, orthophosphate, hardness and alkalinity. The results showed that pH, temperature, hardness, TAN, nitrite, nitrate and ortophosphate were not significantly different between treatments (P>0.05), while dissolved oxygen and alkalinity were showed different significantly (P<0.05). On the fourth day of culture with a density of 4 fish L-1 and 6 fish L-1 has led to water saturation in the culture media. Dynamic of water quality was started on the third day of culture, whereas nitrites could not be converted to nitrate maximally. High levels of nitrate in the snakehead culture indicated that that this culture could be combined with an integrated aquaculture with plants.
Highlights
Snakehead fish (Channa striata) is a native species of Asia and Africa (Ng and Lim, 1990)
In South Sumatra, the economic value continues to increase because snakehead fish can utilized in the form of fresh fish and been used as the material of making crackers, pempek, tekwan and so on (Makmur, 2003)
Snakehead albumin extract is relatively high (2.17 ± 0.14 g / 100 ml), enough to be used as ingredients to increase intake for growing children and patients undergoing wound healing treatments
Summary
Snakehead fish (Channa striata) is a native species of Asia and Africa (Ng and Lim, 1990) This fish is one of the original fish that live in fresh waters in Indonesia, such as watersheds in Sumatra, Kalimantan and Java (Muthmainnah et al, 2012). In South Sumatra, the economic value continues to increase because snakehead fish can utilized in the form of fresh fish and been used as the material of making crackers, pempek, tekwan and so on (Makmur, 2003). Snakehead albumin extract is relatively high (2.17 ± 0.14 g / 100 ml), enough to be used as ingredients to increase intake for growing children and patients undergoing wound healing treatments
