一、起捕时间天然水域河蟹起捕时间一般在9月中下旬,由于此时水温仍较高,河蟹可继续生长。适宜的起捕时间应为10月上旬开捕,持续到11月下旬。二、捕蟹工具目前捕蟹大多采用蟹网、蟹钩、灯诱、闸口张网、人工捕捉等方法,其效果不甚理想。在封闭性湖荡里,由于湖面面积较大,荡底地形复杂,又有多种水生物生长,河蟹起捕率较低。经试验比较,竹簖是湖荡较为理想的起捕工具。三、捕蟹方法选择水位较深(1.2～1.5米)、水质清晰、无水生植物或水生植物较少的地方下簖,将竹箔以直线或有规律的弯曲横截于荡面,露出水面20～30厘米,每樘 First, the catching time Crab catch time in the natural waters generally in late September, due to the water temperature is still high at this time, crabs can continue to grow. Appropriate catch-up time should be early October hunting, lasted until late November. Second, crab tools crabs currently used mostly crabs, crabs hooks, lights lure, gate Zhang net, artificial capture and other methods, the effect is less than ideal. In the closed lake, due to the lake area is larger, the bottom of the terrain complex, there are a variety of aquatic organisms, crab fishing rate is low. After the test comparison, bamboo shoots are relatively ideal lake hunting equipment. Third, the method of selecting crabs The water depth (1.2 ~ 1.5 m), clear water quality, no aquatic plants or aquatic plants in the place where the next 簖, the bamboo foil in a straight line or regular bending transverse to the surface, exposing the water 20 ~ 30 cm, each 樘
