Where can loach fry be bought, and what are the breeding methods?
Loach is a aquaculture project that has started to emerge in recent years. In the past, wild resources made up the majority, but now wild ones can no longer meet market demand, so many farmer friends saw the business opportunity and began using the natural geographical environment of rural areas to start farming. So where can loach fry be bought? How are they bred?
Where can loach fry be bought? How much per fish?
In Huadu District, Guangzhou City, Guangdong Province, artificially farmed Taiwan loach fry, body length 3-5 cm, survival rate 95%-98%, growing environment is freshwater rearing, minimum order 10000 fish, 0.1 yuan per fish; in Jianshui County, Honghe Hani and Yi Autonomous Prefecture, Yunnan Province, Taiwan loach fry, survival rate 95%-98%, body length 6-8 cm, minimum order 10000 fish, 0.03 yuan per fish, etc. The above loach fry prices all come from the Nongxun Network supply hall, for everyone's reference, and do not include logistics costs.
How are loach fry bred and reproduced?
1. Natural spawning reproduction
Place parent loach in the spawning pond. When the water temperature rises above 18°C, place disinfected palm pieces, poplar and willow roots, aquatic plants, etc. in the pond as fish nests. After discovering that the loach have spawned, transfer the fish nests with attached eggs into the hatching pond, and at the same time put in new fish nests for them to spawn again. The hatching of fertilized eggs does not have high requirements for water quality and water temperature, and generally aquaculture water can be used for hatching. The optimum water temperature is 20-28°C, and the fry can emerge from the membrane in about 2 days.
2. Artificial induced spawning reproduction
In April-May when the temperature is suitable, catch the parent loach, select those with soft abdomens, a slightly pinkish color, and signs of imminent spawning, with body length of 12 cm, body weight above 20 g, preferably individuals around 40 g, for drug-induced spawning. For the dosage, each female loach can use 1 carp PG or 5-10 micrograms of LRH-A, and the dosage for male loach is halved. Then place the induced parent loach into the spawning pond and let them spawn and fertilize on their own or perform artificial fertilization. Finally, put the fertilized eggs onto nests and transfer them into the hatching pond for hatching. This method can obtain loach fry on schedule, in large quantities, and in a planned way.
3. Stocking for supplementary reproduction
This is the simplest reproduction method. That is, put an appropriate amount of mature loach into the loach culture water body, but other fish species cannot be stocked first. In the reproductive season, place some artificial fish nests. The loach spawn in the culture pond and hatch in the original pond. The fry can be cultivated in small boxes and then still raised in the original pond.
