Instances of shrimp breeding technology
Material. On day 2, at 2 am, the larvae develop into nauplii have V, Ⅵ period, to be cast algae powder (spirulina) 17 grams, 12 grams of dry yeast. Dissolved retreat cloth pool, fed every 4 hours after 1, at the amount of algae powder feeding × 6 times 17 grams, 12 grams of dry yeast for the × 6 times, as appropriate,[link widoczny dla zalogowanych], under the larvae will increase or decrease drag. For the inhibition of proliferation of bacteria during breeding,[link widoczny dla zalogowanych], since the beginning nauplii soil mold claim 1 vote 0-5ppm, vote the next day after the soil mold claim 1 0.5ppm noon nauplii had metamorphosed into zoea I. 3 days, the larvae have metamorphosed into zoea I and zoea II of the period. L7 grams of powder feeding on algae × 6 times, dry yeast 12 g × 6 times. At noon on day 4 larvae have metamorphosed into zoea I. Head 'feeding algae × 6 times 15 grams of powder, dry yeast 10 g × 6 times, cooked chicken egg yolk 0.5 g × 6 times. Nissan particulate food (0) 5 g × 6 times, currently with card payment B. P10 g × 6 times. 5 days, the larvae have metamorphosed into zoea Ⅱ period. The first 4 days of feeding the same amount. 6 days, the larvae have metamorphosed into mysis larvae I,[link widoczny dla zalogowanych], each of mysids fed Artemia larval head to continue feeding in 15 particle bait Nissan (0) 5 g × 6 times a day with card payment B. PIO g × 6 times. 7 days, the larvae have metamorphosed into mysis larvae II period. Each Mysis larvae fed Artemia at 25. Artemia pool to maintain a certain density, the density should be reduced in time. 8 days, the pool of larvae have metamorphosed into mysis mysis larvae of each larval stage Ⅱ fed Artemia at 30. 9 days, the pool has been metamorphosed larvae larvae I. At the end of each larva were fed Artemia 5o. The first l0 days, the pool has been metamorphosed larva larva stage Ⅱ. Larvae at each end of Artemia fed 100. The first 11 days, the pool has been metamorphosed larva larva larva Ⅱ at the end of each fed 150 Artemia. 12 days to l4 days, the larvae change from the larva to larva IV, VI period. Day 4 clam custard cast (lO0 g + clam whole egg 2) and larvae at the end of each fed 200 Artemia larva always check the health status and gut fullness. Control the amount of Artemia fed to save production costs. 7. Emergence of the first 14 days of emergence at 8 pm, the use of Penaeus shrimp have a strong phototaxis, with 100 watts when emergence larvae to induce emergence mouth, emergence speed. The dry volume count, emergence 755,000, emergence rate of 27.5. Second,[link widoczny dla zalogowanych], the analysis and discussion with the head of the shrimp maturation promoting measures to lay eggs, so a lower survival rate. It is generally the highest level of emergence 3OZ, 27.5 emergence of the pool, indicating that better management or Ⅳ stage larvae from feeding clam custard is feasible after emergence, check the breeding pool, small bait.
