“…Some of the demersal fish species recorded live near the sea surface as juveniles, including beaked sandfish and bluebottle fish Nomeus gronovii [ 56 ], and are captured by terns at this life stage. Like beaked sandfish, juvenile Cape hake Merluccius capensis can occur near the surface during the daytime [ 57 , 58 ]. Small hake may be captured early in the morning as they migrate to the surface at night to feed on fish and crustaceans [ 56 ].…”

“…In shallow waters Hobson (1966) noted that fishes could be identified to species by the outlines of stimulated bioluminescence they generated as they swam. Movements of fish schools produce intense stimulated bioluminescence at the surface, which has been used commercially to locate schools of pilchard (Sardinops ocellatus), anchovy (Engraulis capensis), and horse mackerel (Tracburtls trachclvus) (Cram and Schulein 1974). Equivalent observations are lacking from midwater environments; however, certain depths have a much greater potential for stimulated bioluminescence than others (Widder et al 1989).…”
