Problems solved by technology

[0003] At present, there are few methods and devices for counting fish, shrimp and crab fry in aquaculture and measuring the number of survivors. Zhu Congrong invented a method for counting fish fry based on machine vision. The combined method establishes the relationship between the number of pixels occupied by fry and the number of fry in the image, and thus counts the fry

Abstract

The invention discloses a seed survival counting device based on the behavioral biology of red crayfish. The main body is a wooden side frame, a nylon net is arranged at the bottom of the wooden side frame, and a floating block is respectively arranged at the four corners of the wooden side frame : Four boards form an integrated wood frame through mortise and tenon structure; the bottom surface of the wood frame is provided with a groove, the nylon mesh is embedded in the groove, and then embedded with a rubber strip to fix it; the top surface of the floating block is provided with two vertical intersecting grooves. Grooves, the four corners of the board side frame are stuck in the grooves to nest four floating blocks. The invention solves the technical problem of measuring the survival number of shrimp seedlings in the prior art from fishing, transportation to stocking.

Description

technical field [0001] The invention relates to a seedling survival counting device based on the behavioral biology of red-clawed crayfish, which belongs to the field of measuring the survival number of red-clawed crayfish seedlings from fishing, transportation to breeding. Background technique [0002] Red claw crayfish (Cherax quadricarinatus), also known as "Australian freshwater lobster", is native to Australia. It looks like a lobster in the sea. It is one of the most valuable freshwater economic shrimp species in the world. The body color of the shrimp is brownish green, and there is a membranous bright red band on the outer top of the claw, so it is also known as the red claw crayfish. Red crayfish individuals are generally 50-100 grams, and the largest individual is 500-600 grams. It is a freshwater shrimp with strong adaptability. Red claw crayfish has a wide range of food habits, fast growth, tender meat, delicious taste and rich nutrition. [0003] At present, t...
