Advantages:
Because of the way it is made, with a number of rings around the bottom with a line called a purse-line through them, when it is pulled the line draws the rings together. It prevents the fish from swimming down to escape the net. This type of seine is useful for fish the school close to the surface, such as sardines, mackerel, anchovies, herring and certain species of tuna and salmon.
Disadvantages:
Purse seines can involve the bycatch of non-target species, which can put too much pressure on fish stocks.
