The bighead carp can grow about 1 kilogram in a year under the condition of sufficient feed, and the specific weight gain is related to the feeding management technology. It takes about 2 years to culture bighead carp artificially, but of course, under the condition of modern culture technology, if the specimen is large, it can reach the market specification of more than 1.5kg/tail after one year of culture. The bighead carp is usually caught in June-July when some of the fish that have grown to more than 1.5 kilograms are harvested and marketed, and the rest of the fish are harvested and marketed in winter, with adult specifications ranging from 1.5-2 kilograms and 2.5-4 kilograms per tail.
First, bighead carp can grow more than one year
1, pond culture in the conditions of sufficient feed, bighead carp can generally be a year of weight gain of about 1 kilogram. Bighead carp weight gain speed and feeding management technology has a lot to do with its growth rate is very fast, most common individuals in more than 10 kilograms.
2. Bighead carp is not a kind of fish, it is a collective term for silver carp and bighead carp (Hypophthalmichthys nobilis). Because these two kinds of fish are very close to each other in terms of looks, habits, and feeding habits, they are collectively called bighead carp.
3, breeding bighead and silver carp, the traditional ratio of bighead and silver carp is 3:1, that is, 3 silver carp with 1 bighead carp. According to the production practice, bighead carp stocking structure, the proportion of bighead carp is less than 20% or the proportion of bighead carp is more than 80%, the growth rate of bighead carp is faster; when the proportion of bighead carp stocking between 20%-80% will inhibit the growth rate of bighead carp. When bighead carp is the main fish, bighead carp should be stocked in small quantities or not at all.
Second, bighead carp farming how long can be marketed
1, artificial bighead carp farming generally need about 2 years, the first year of breeding fish species, the second year of breeding adult fish. Of course, under the conditions of modern farming technology, if the specification of the fish species is larger, after a year of farming can also reach the market specification of more than 1.5kg/tail.
2, bighead carp can be caught and listed all year round, and in June, it starts to catch big and keep small, that is, in June-July, it starts to catch and list some of the fish that grows to more than 1.5 kilograms, and the rest of the fish are caught and listed in the winter, and the specifications of the adult fish are 1.5-2 kilograms per tail and 2.5-4 kilograms per tail. Do not hurt the fish when catching, so as to avoid injury to the fish body and disease infection during the overwintering period, resulting in the death of the situation.
