national manufactures actively use beef meal, poultry meal and dried blood to
produce fishing baits and groundbaits. Experimental data show that these
products are attractive for fish, only if fish are familiar with them.
Some tunas such
as skipjack (Katsuwonus pelamis),
little tunny (Euthunnus affinis) and
yellowfin (Neothunnus macropterus) respond
positively to aqueous extracts of tuna flesh as well as to tuna blood (Tester
et al., 1955). In contrast to these results, whole beef blood and beef blood
plasma are not attractive, while whole beef blood is even repulsive perhaps due
to its bright red color.
sockeye salmon, Oncorhinchus nerka,
are attracted by extracts of beef liver and beef heart, if only fish grown in these
byproducts (McBride et al., 1962). Fish grown in these feeds do not respond to
extracts of zooplankton, brine shrimp (Artemia
salina), squids and some natural oils.
that the use of meat meals and dried blood in fishing baits and groundbaits needs
inevitably leads to overrunning these products, their losses and,
in final sum, to the eutrophication of water bodies.
