摘要
研究了光伏太阳能板覆盖下养殖池塘中河蟹幼蟹的生长特性。结果表明,在光伏太阳能板下水环境中,河蟹幼蟹的背甲宽生长表现为龄期与生长的线性关系;幼蟹体重生长显示出龄期与生长的幂函数关系。与常规养殖环境中幼蟹生长特征相比较,无论幼蟹背甲宽或是体重,光伏太阳能板下水环境中幼蟹生长速度明显低于常规养殖环境中幼蟹生长速度,同时大规格幼蟹比例明显降低。光伏太阳能板的建造,改变了水体的光照模式、溶氧量和水草生长等环境因子,影响了幼蟹生长因素。
The study of the growth characteristics of juvenile crabs in the aquaculture pond with Photovoltaic solar panels covered on it shows that the growth of the width of carapace on juvenile crabs under such environment and their age depend linearly on each other; meanwhile the growth of the weight of juvenile crabs and their age manifest as a power relationship between each other. Compared with growth characteristics of juvenile crabs in conventional aquaculture environment, crabs who grow in the photovoltaic solar panel covered aquaculture pond have a much slower growth rate than those who grow in the conventional aquaculture environment, the percentage of juvenile crabs with big size also decreases significantly at the same time. Such phenomenon occurs due to the manufacture of photovoltaic solar panels, which changed environment factors of the water body including illumination type, dissolved oxygen amount and growth of waterweeds, these ecological factors are precisely the main constraints who influence the growth of juvenile.
