摘要
对克里米亚黑海Donuzlav Liman海域牡蛎长牡蛎三倍体口贝的线性增长率和重量增长率进行了调查。给出了全牡蛎质量(W, g)与壳高(H, mm)之间的定量关系(用公式W = 7·10-5·Н3.1, R²= 0.78表示),以及全牡蛎质量(W, g)与壳长(L, mm)之间的定量关系(W = 3·10-4·L3.12, R²= 0.65)。三倍体牡蛎T20的最大线性生长率出现在4月(1.15 mm / d)、6月(0.50 g / d)和8月(0.61 g / d)。结果表明,27%的三倍体牡蛎T20在6个月后能达到商业规模。建议在黑海地区的贝类养殖场使用T20大小的太平洋牡蛎作为种植材料。
Growth and terms of obtaining marketable triploid oysters in Donuzlav Liman (Black Sea, Crimea)
The rate of linear and weight growth of triploid spat of oyster Crassostrea gigas in Donuzlav Liman (Black Sea, Crimea) was investigated. A quantitative relationship between the mass (W, g) of the whole oyster and the height of the shell (H, mm) is given (it is described by the equation W = 7 · 10-5 · Н3.1, R² = 0.78), as well as a quantitative relationship between the mass (W, g) of the whole oyster and the length of the shell (L, mm) (W = 3 · 10-4 · L3.12, R² = 0.65). The maximum rates of linear growth of triploid oysters T20 were registered in April (1.15 mm per day), of weight growth – in June (0.50 g per day) and August (0.61 g per day). It was shown that 27 % of triploid oysters T20 can reach commercial size after 6 months. It is recommended to use Pacific oysters of T20 size as a planting material on the shellfish farms in the Black Sea region.
