There larvae treated with silk worms fed for 2 weeks. The next two weeks the larvae are already a fry 3-4 cm were fed pellets. Giving pellets in the morning and evening to taste. Five days after eating pellets, cork no longer receive the silk worm. Furthermore, the snakehead seed has reached the size of 8-10 cm were transferred to the cement pond measuring 3 mx 10 mx 1.12 m to be raised up to the size-weighted consumption of 200 g per head. Measuring 8-10 cm cork can also be sold as seed, the average sales per month 8,000-10,000 seed heads. Andhi fix the price of seed cork was 1,000 per cow. This means that from the sale of seeds he obtained a turnover of Rp 8-million-Rp10-million every month. Buyers come from Jepara (Central Java), Pacitan (East Java), and around Yogyakarta. In the enlargement phase Andhi feeding pellets. The number of pellets were given as much as 3% of the total weight of the whole fish every day for 150-180 days cultivation. As an illustration of the cork weighs 1.000 5 g per cow, Andhi give 5 kg of feed per day. According Andhi kilo of feed can be produced from 0.7 kg of meat. "That number could still increase up to 0.8 to 0.9 kg if the cork was raised intensively," said 25-year-old man. For example, by maintaining the quality of water and feed. According Andhi enlargement that took place during the 5-6 month set pool water must not exceed a height of 0.8 m. "When the position of the high water, cork easily jump out of the pool," said Andhi. Cork is usually jump in the pool if the water quality is bad. Behavior was also true in nature. To solve it Andhi installing nets around the pond as high as 1 meter. Fish cannibals So far there has been no research on the cultivation of cork in the pool so that some important parameters such as stocking density, life passing rate, feed conversion during the cultivation of the right is not certain. According to the teaching staff of the Faculty of Fisheries at the University of Hull Mangkurat Banjarbaru, South Kalimantan, Lucky Wise, cork cultivation of fish consumption is not the same as another. "Cork including major carnivores in the ecosystem chain. So when cultivated need to feed a lot, eg 2 kg of feed to produce 1 kg of cork, "said Lucky.
