Title: Terminal tackle for squid angling
Inventor: SUDO AKIRA
IPC: A01K91/06
Filed: 2002-03-26
Abstract: <P>PROBLEM TO BE SOLVED: To improve conditions in which a squid pulls a bait fish and escapes in a state without hooking on Yaen (a tackle for angling the squid) while loosening a main line and regulating the tilt degree of the Yaen after arrival of the Yaen for angling the squid at the bait fish in a terminal tackle for squid angling.  <P>SOLUTION: The terminal tackle for squid angling is obtained by mounting a hook 1 on one side of a stainless steel rod 2, mounting a spring-like fixture 3 and a swivel 4 on the other side. The hook 1 is hooked around a caudal fin of the bait fish 5 and the swivel 4 is connected to the main line 6 to release the bait fish 5 in the sea. After the squid starts preying on the bait fish 5, the main line 6 is passed through a front guide ring 8 and a rear guide ring 9 of the Yaen 7 and cast into the sea. When the Yaen 7 reaches the bait fish 5, the swivel 4 is passed through the front guide ring 8 and the fixture 3 is subsequently passed therethrough. When the fixture 3 is passed therethrough once, the fixture 3 is caught with the front guide ring 8 of the Yaen 7 without slipping to the rear even if the squid 10 tries to escape while preying on the fish bait 5. The terminal tackle is a fishing tackle designed to always keep the position of the Yaen 7 under the squid 10.  <P>COPYRIGHT: (C)2003,JPO
