I would be very glad, if you be able to point me on some research on the impact of change in mesh size in static gears on fish and invertebrate catchability. Something like “increase in mesh size by 50% will reduce catches by 30% and fish/shrimp size would increase by 10%.” Information from trawls also would be useful.
There have been a number of studies that have investigated the impact of mesh size on catchability in static gear, such as gillnets and trammel nets. Here are a few examples:
It is important to note that the impact of mesh size on catchability can vary depending on the specific species and fishery being studied. It is also important to consider other factors, such as the fishing gear configuration and fishing effort, that can also affect catchability.
