What are some common methods of fish harvesting?

B is the correct choice because it includes techniques that are widely used in aquaculture and commercial fishing practices. Seining involves using a large net that is drawn through the water to encircle fish, making it effective for capturing larger schools of fish near the surface or in shallow waters. Trapping entails the use of traps or pots that lure fish inside, allowing for selective harvesting with minimal bycatch. Netting, which can refer to various types of mesh nets, is another common practice, with gill nets, purse seines, and cast nets being specific examples that cater to different fishing scenarios. Pumping can refer to a method used to harvest fish from certain aquaculture systems or environments, particularly where water is being moved and fish can be collected directly via pumps.

For example, hunting and burning are not viable methods for harvesting fish, and while fishing with hooks is a serious and traditional method, it does not encompass the variety of techniques that exist for harvesting aquatic species. Catching fish with chemicals raises significant environmental and health concerns, making it an ethically and legally restricted practice in many areas. Thus, the comprehensive approach presented in option B reflects
