Hi. I want to assess the diversity of fish from 10 sampling sites at temporal scales. However, at each site I am going to use only 1 fishing gear to catch the fishes. If I want to prepare 5 replicates per site/sampling, is it valid if I take the replicates from the same fishing gear? I'm planning to use stratified random sampling technique to prepare these replicates. Thank you.
Please have a look at this useful researchgate link and PDF attachments.

Yes depend on fishes if according to the fish gear mesh size. Also you can use 1 net and do the replicate.

Do you plan to take 5 replicate samples per sampling event per site ? These may not be independant, as with every sampling, fish would be caught and subsequent catches would have less fish to catch from, as well as scaring fish away from the area. It would be better to sample in different areas, at least 25-50 meters apart for the same sampling event on a day.
Hi. Thank you for the replies. By the way, I'm going to use estuarine set bag net (ESBN) to catch the fishes.
