1, the wild common carp fry 1 year can only grow to 1 two or so, 3 years to grow to half a catty or so, grow to 1 catty at least 5 years. 2, artificial cultivation of the common crucian carp half a year of growth can reach a weight of more than 0.4 catties, 1 year about 0.8 catties or so, that year in May stocking can be caught in December on the market. 3, the project crucian carp 2-3 years after the weight can reach more than 3 catties. 4, if you want to artificially cultivate carp can be put in mid to late April, each mu of pond can be put in the fish fry. 4, if you want to artificially cultivate crucian carp, you can put the fry in the middle and late April, each mu pond can put 10000-25000 tails.
