Title: Part for forming fish shelter
Inventor: TSUKADA KAZUHIKO
IPC: A01K61/00
Filed: 2001-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a part for a fish shelter, resistant to the biting damage of shipworm, etc., developing fish attracting effect and disappearing by decomposition to dispense with the work for the recovery of useless shelter. SOLUTION: The part for a fish shelter to be placed in the sea is covered with a covering layer composed of a biodegradable resin to protect the core material from the biting damage of shipworm, etc., and enable the gradual decomposition with microorganisms, etc. Since the core material consisting of wood is decomposed and eliminated after the decomposition of the covering layer, the shelter eventually vanishes in the sea to dispense with the work for the recovery of useless shelter. The decomposed biodegradable resin forms a nutrient component for microorganisms to attract the microorganisms and fish is attracted by the microorganisms to achieve the fish-attracting effect of the shelter. Similar effect is developed by the decomposition of the wood used as the core material and, accordingly, the fish-attracting effect is continuously developed throughout the whole life of the shelter.
