Description
Technical Field
The invention relates to an aquatic product sample fishing device, which is used for accurately fishing through the matching of a long rod and a net bag, in particular to a moso shrimp sampling and shoveling net.
Background
Acetes chinensis often inhabit in groups in shallow sea at silt bottom with water depth not more than 50 m in river estuary, estuary and around island, and are not found in ocean or deep sea areas. The Bohai sea Chinese penaeus chinensis inhabits the middle and lower layers of the sea water and sometimes rises to the surface layer in summer. The swimming ability is weak, and the swimming ability is reciprocated with rising and falling tide. In winter, the water temperature drops and moves slightly to the deep. After spring, spawning in shallow water areas near river mouths or near shore; along with the gradual rise of water temperature, the range of the spawning site is gradually enlarged. The female and male shrimps are mated after the female gland is mature, the mature sperms of the male shrimps are discharged into the fertilized sac near the front edge of the abdominal surface of the genital plate of the female shrimps, and the ova are fertilized when discharged from the genital orifice. Fertilized eggs are semi-sinking and need to be transformed into young shrimps after hatching for a plurality of times through the nauplius larva period, the daphnia larva period, the mysid larva period and the young shrimp period. 2 generations were generated a year. The length of female shrimp bodies in the overwintering shrimp group is mostly 25-35 mm, the length of even few female shrimp bodies reaches about 40 mm, the length of male shrimp bodies is 20-30 mm, the spawning period is from 5 months late to 7 months middle, and the main spawning period is 6 months. The descendant is the 1 st generation, or summer generation. The female shrimps in the summer generation have the body length of 20-30 mm, the male shrimps have the body length of 16-25 mm, the oviposition period is from 7 to 9 months, and the main oviposition period is 8 months. Most of the overwintering shrimp groups die immediately after spawning; after spawning in the summer generation, a part of the shrimp continuously survives and forms an overwintering shrimp group together with the offspring (namely, the 2 nd generation, or called as the autumn generation) bred in the summer generation. The Macrobrachium nipponensis is produced for 2 generations in Bohai sea, and also includes Penaeus japonicus in Western Japan. In the Bohai sea, the Chinese acete chinensis forms two independent groups, namely a Liaodong Bay group and a Bohai Bay western group. Because the distribution area is small, the life cycle is short, and the resource quantity changes greatly every year.
The existing catching and fishing net for the macrobrachium nipponensis samples is manually held, because the swimming speed of the macrobrachium nipponensis is high, the catching efficiency of the manually held catching and fishing net is low, the catching range is limited by manpower to a small extent, and the cost of ship catching for the small-batch sample catching is too high.
