Background information and definitions
Using a smaller mesh size for fishing nets may reduce the risk of marine and freshwater mammals becoming entangled (Northridge et al. 2017). However, the feasibility of this intervention will depend on the size of the target catch species. There may also be issues with implementation where minimum mesh size regulations are in place to reduce unwanted catch of juvenile animals and/or smaller species.
