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 cherax quadricarinatus behavior biology-based larvae survival number metering device. A main body is a wood board side frame; the bottom part of the wood board side frame isprovided with a nylon net; four corners of the wood board side frame are each provided with a floating block; four wood boards are formed into the integrated wood board side frame through a mortise and tenon structure; ditches are formed in the bottom face of the wood board side frame; the nylon net is embedded into the ditches, and then rubber strips are embedded to fix the nylon net; two vertically intersected grooves are formed in the top surface of each floating block; and the four corners of the wood board side frame are stuck into the grooves so as to nest the four floating blocks. The larvae survival number metering device solves the technical problem of survival number metering in the process from fishing to transportation to stocking of shrimp larvae in the prior art.

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...
