Problems solved by technology

However, there is no effective and feasible specific method for the assessment of fish output in aquaculture.
At the same time, due to the limited monitoring range and long monitoring distance of the aquaculture site, it is impossible to scientifically evaluate the growth, survival status and yield of farmed fish

Embodiment 1

[0072] Put a batch of koi fry in five ponds, the number and size of koi fry in each pond are the same, and they are all healthy. After three months of breeding time, calculation and statistics are performed according to steps S110-S160 to obtain the following table, which is the forecast result of koi production in each pond in the first 3 months before pulling the net out of the pond.

[0073]

[0074]

[0075] It can be seen from the table data that the average prediction accuracy of this algorithm can reach more than 79% in the prediction of the number of reared koi fish out of the pond, and the prediction accuracy of the average weight specification of the pond can reach more than 84%, which can basically accurately reflect The production of fish and also meet the application needs of the farm.

Abstract

The present application relates to the field of aquaculture, in particular to a method for predicting the fish yield, comprising: collecting feeding image information of fish from above the water surface toward the water surface; extracting fish head and mouth triangles from fish feeding images; calculating the area of the extracted head and mouth triangle of the fish; calculating the actual head-mouth triangle area by the extracted head-mouth triangle area of the fish; calculating the fish weight by the actual triangular area of the head and mouth of the fish. The beneficial effects realizedby the application are as follows: the growth and survival state of the fish can be evaluated by the feeding image information of the fish collected at the feeding time period of the bait; The fish head triangle can be extracted from the fish feeding image information, and the fish head triangle area can be calculated. Finally, the fish body weight, that is, the fish output, can be calculated, andthe final fish output can be evaluated.

Description

technical field [0001] The invention relates to the field of aquatic products, in particular to a method for predicting fish output. Background technique [0002] In the aquaculture industry, farmers and farming companies need to regularly check the growth and survival status of farmed fish, estimate the final output of farmed fish, and formulate a reasonable bait feeding plan to ensure The quality and safety of aquatic products and the safety of production and operation. However, there is no effective and feasible specific method for the assessment of the output of fish ponds in aquaculture. At the same time, due to the limited monitoring scope and long monitoring distance of aquaculture sites, it is impossible to scientifically evaluate the growth, survival status and output of farmed fish. [0003] Therefore, how to evaluate the fish growth, living state and fish final pond yield is an urgent problem to be solved in this field. Contents of the invention [0004] The ...
