1. Metamorphosis When the hook-and-mosquito mistletoe is on the fish's rays and fins, the fish is stimulated to secrete a viscous substance that envelops the larvae. The larvae use the secretions as a nutrient to complete the metamorphosis process and turn them into Aberdeen.
2. The harvester carefully transfers the fish to the Aberdeen cultivation pond, allowing the Aberdeen to free fall off at the bottom of the pool, or to hold the fish in a container first. After the Aberdeen falls off, it is collected in a dense net cage with flowing water. Farming.
(b) The breeding larvae of young larvae are suitable for muddy bottom waters with sufficient sunlight. The transparency of the water quality should be more than 40cm, the oxygen content should not be lower than 4mg/L, and the pH should be 7-8.
Astragalus membranaceus directly absorbs inorganic dissolved nutrients from the body of water and filters microscopic plankton such as bacteria, diatoms less than 50 microns in diameter, dinoflagellates, tiny rotifers, and single-celled protozoa. Later, as Tsai grows up, small plankton, such as phytoplankton, rotifers, and small crustaceans can be filtered and eaten above 50 microns.
Aberdeen falling from the fish is only 0.3 to 0.5 mm. In an environment where the water temperature is 20 to 30°C and the water quality is appropriate, the average monthly growth of Aberdeen is 0.5 to 1.0 cm, and the crust quality is gradually thickened. When the larvae grow to more than 1 cm, they are called cubs. The larvae grow to more than 10 cm and are called pupa.
The methods for breeding young cubs into pupa include hanging, raising, rearing, earthen pond raising and rearing. At present, the most popular rapid culture method is maintenance.
1. Hanging is drilled in wings with a body length of 3 to 5 centimeters and is raised in nylon 9 wire in a water depth of 9-15 cm. This breeder grows slowly.
2. Bottom rearing is a form of culture in which young cubs are stocked directly in ponds or rivers. Generally, 1,000 animals are stocked per square meter, and can grow to more than 12 cm in 2 years.
3. Boxing is a culture method of raising young cubs to cages. With this method of breeding, the shell length can be increased by about 5 cm in 4 months. It is a better way of farming.
4. The earthen pond culture is a method of digging a small earthen pond to breed at a water level difference. Generally, 4 to 6 square meters of earthen ponds can be stocked with 5000 pups of 2 cm or more in length.
5. Nursing is the way that young cubs are packed into quail for breeding. In early June, the young pigs, 0.5 to 0.8 cm in length, will be stocked at a density of 70 to 80 per square meter. By the end of December, 60% of the farmed eggs will have a body length of 6.5 cm or more.
Hemorrhoids grow very slowly. When the kayaking is done in the third year, the zygomatic valve is fully developed. By the fifth year, it has reached sexual maturity and has reproductive capacity.
