Fish cold-blooded‚ limbless‚ completely aquatic vertebrates‚ having gills‚ commonly fins‚ and typically elongated torpedo-shaped body mostly covered with scales. Fish are usually grouped into four classes‚ three living (Agnatha‚ Chondrichthyes‚ and Osteichthyes) and one extinct (Placodermi): 1. Agnatha‚ the primitive jawless fishes‚ including the cyclostomes (lampreys and hagfishes) and extinct armoured fishes known as ostracoderms‚ none of which has gill arches (bony frames for the gills);

The Fish by Elizabeth Bishop Bishop uses literary devices‚ especially similes‚ metaphors‚ tone‚ and imagery to convey her theme of admiration for survivors of life’s difficult battles‚ in this case the fish‚ although at first she failed to admire and appreciate the fish. Bishop also doesn’t realize how beautiful the fish is at first‚ but she eventually finds beauty in the fish. Bishop’s tone of aloofness in lines 5-10 shows that first she is disappointed in what she thought was a big catch.

Fish have been a protein source throughout history. Early fishing primarily involved individuals capturing fish near their communities for consumption or trade. Ships gave fishers access to ocean-based fisheries. Commercial fishing became industrialized by the late nineteenth century‚ as technological innovations helped locate‚ catch‚ and process fish. In addition to fish living in natural freshwater or saltwater fisheries‚ fish cultivated in fish farms ’ ponds or tanks represented approximately
