Betok fish is very popular with the people because of the delicious and tasty taste of the meat, therefore this type of fish is quite potential for cultivation. (Muslim 2008) in (Anggara et al 2013). Most people who cultivate betok fish (A.testudineus, Bloch) do not understand their character or behavior, so that many farmers experience complaints in maintenance, especially in their growth and survival. As an alternative to the maintenance of Betok fish (A. testudineus, Bloch), the growth rates and viability of the Betok (A. testudineus, Bloch) fry were reared in a container using a shellter. The research design used was an environmental design RAL (completely randomized design) consisting of 4 (four) treatments and 3 (three) replications. The treatments were as follows: Treatment A: Betok fish seeds (A. testudineus, Bloch) without treatment (control), Treatment B: Betok fish seeds (A. testudineus, Bloch) were given a bamboo shellter ,, Treatment C; Betok fish (A. testudineusBloch) was given a coconut shell shellter, Treatment D: Betok fish (A.testudineusBloch) was given a paralon shellter. The results showed that betok (A. tetstudineus, Bloch) seeds were maintained using a shelter (Treatment C and B) resulted in better survival rates (99.35% & 98.07%) than treatments A and D (96.15% & 96.79%).

Dipping Time

The thyroxine has been known as a hormone that can increase fish growth especially in the larvae stage. The provision of hormone thyroxine on larvae fish can be conducted through dipping. Determination of dipping time are very important to increase growth. The purposes of this research are determining the optimum dipping time for the growth and survival rate of snakehead larvae. This research was done at Laboratorium Dasar Perikanan, Aquaculture, Faculty of Agriculture, University of Sriwijaya, Indralaya. The method used Competely Randomized Design (RAL) with five treatments and three replicates, with dipping time are 24, 27, 30, 33 and 36 hours. The parameters observed are the absolute length growth, absolute weight growth, survival rate of larvae and water quality (temperature, pH and disolved oxygen). The results showed that the duration of immersion in thyroxine hormone solution in snakehead larvae showed relatively faster growth on treatment (P5) with 36 hours of dipping time. While the regression test result showed the optimal growth of snakehead larvae at the time immersion for 27,92 – 29,49 hours. Thyroxine hormone increased the growth of snakehead larvae but has no statistically significant effect. The length of time of thyroxine hormone 24-36 hours with a dosage of 0.1 mg l-1 did not affect the survival of snakehead larvae. Water quality of maintenance media is still tolerance for supporting the growth and survival of snakehead larvae.
