ARTIFICIAL SPAWNING BANK FOR BIGFIN SQUID

摘要

PPROBLEM TO BE SOLVED: To provide an artificial spawning bank for bigfin squid (Sepioteuthis lessoniana) that can not only help the spawning of bigfin squid, but also consider the habitat environment for the larvae of the squids after spawn deposition, for example, secures the habitation space for the larvae of the squids and the feed organisms. PSOLUTION: A spawn deposition unit 4 is constructed by attaching a plurality of spawn deposition base 6 onto the base plate 5 vertically. Then, the spawn deposition units are arranged to the structural body to give an artificial spawning bank. In this case, the spawn deposition base 6 is constituted by filling the water-permeable cylinder case with shells or a material similar to shells. Further, a plurality of openings with a cross section enough for the larvae of bigfin squid to pass through, out and in, are suitably bored. PCOPYRIGHT: (C)2004,JPO&NCIPI
