Generally speaking, anti-seasonal breeding is to put seedlings before the winter comes, breed over the winter, and wait until the next year when there are fewer commercial fish in the market, the profits are considerable, and many farmers use this anti-seasonal breeding mode to fight for high prices. However, what are the "advantages and disadvantages" of the California perch's counter-seasonal farming model? Xiaobian is here to share with you.
advantage
1, the rarity of the goods is expensive, earlier out of the fish, fish prices are higher, the emergence of anti-seasonal fry is based on this, the wrong peak out of the fish, in the highest market when the fish, fight high profits.
2, "anti-seasonal seedlings" do not need to build a winter shed for wintering, generally do not need to be paired with fresh ice, feeding workload is not large, feed cost is low.
inferior position
1, seedlings "expensive"
The anti-seasonal seedlings are the highest temperature in the summer, the temperature difference between the water temperature, the temperature of the fish car is 26 degrees, the water temperature of the pond is about 36 degrees, the difference is about 10 degrees, the temperature difference is too large, and it is easy to cause the fish to "cramp".
2. There are many diseases
Mortality is high and survival rates are low; the quality of California sea bass fry directly affects the efficiency of later rearing. The selection of healthy and high-quality seedlings can improve the survival rate of seedlings, thereby providing a reliable guarantee for the later stage of adult fish farming, so that the efficiency of California perch culture can be improved.
3. Spawning problems
In March and April of the following year, California perch faces spawning, and most of these seedlings will be precocious, so they will generally ovulate before the adult size is marketed, and the cost of bait will naturally be high. Coupled with the low water temperature, the breeding cycle is longer, and the breeding risk is greater.
4. High risk of wintering
California bass need to go through a winter of low water temperature culture, overwintering period is prone to water mold, oblique tubeworm, Noka's and other high damage diseases.
Finally, I would like to warmly remind all breeding friends:
There are still many problems in this kind of anti-seasonal breeding, and the above-mentioned disadvantages of anti-seasonal breeding must be understood. Don't blindly see that others earned money last year, this year quickly buy fish fry and raise them in the pond, blindly following the trend is easy to fall into the pit.
