|
|
| Abstract: |
| This experiment was done on 23rd, July, 1982-12th, Oct., 1982, on the raft in the scallop culture area of Shi-miao Sporelings Breeding Farm of Dalian Fisheries CultureCompany. The breeding of the sporelings of Undarla pinnatifida (Harv.) Sur. in Sea have many advantages: little investment, lower production cost, and higher efficiency. It is a better method of sporelings breeding nowadays. The suitable date for sporelings collecting is from the last part of June to the last part of July, or to the first part of August. The most suitable density of seedling collection is 150-200 zoospores per visible field (100×). If the seedlings breeding ropes are used directly for cultivation, the suitable density will be 50 zoospores per visible field (100×). Fertilizer cannot be applied in the sea area with 6-10m transparency, containing N 40-50 (±) mg per m3, P 10 (±) mg per m3, and least floating soil and other sea-weeds. The most suitable breeding depth is 2-3m. The seedlings breeding ropes may be washed or brushed in about every 8 days. |
