Description

Technical Field

[0001] The utility model relates to the technical field of fish measuring boards, in particular to a foldable and portable fish measuring board. Background Art

[0002] Fish length (total length, body length) is a key biological indicator in aquaculture and fishery ecology. It reflects fish growth and population structure under varying environmental conditions and holds significant application value. Monitoring the length structure of fish populations and communities is fundamental to aquaculture performance evaluation and fishery resource management. In the aquaculture industry, monitoring the growth of farmed fish often requires regular capture and measurement of their size.

[0003] Traditional fish length measurement tools include plastic and stainless steel rulers for small fish, and plastic and iron measuring tapes for larger fish. However, these conventional tools are not specifically designed for fish length measurement. In practice, they suffer from large measurement errors, slow measurement speeds, limited measurement ranges, and are prone to breakage or rust. To improve fish measurement efficiency, a dedicated fish measuring board is required.
