Description 411-423
Seahorse
populations show social, spatial patterns in the wild and coupled with its biology
that renders them more vulnerable to intense fishing. Seahorses are mainly
exploited through gears like shrimp trawl net, country trawl net and shore
seine operation and their catch is considered as fortuitous. During the demanding
period target fishing like skin diving is also done. The ecosystem of the study
area is well diverged with seagrass, seaweed and coral reef, which form the
suitable habitat for these unique creatures. Present study provides the base
line information regarding the species abundance, catch per unit effort, occurrence
of brooding males, sex ratio for the four commonly found seahorses in the Gulf of Mannar. Length – weight relationship and growth
studies were restricted to the dominant species H. trimaculatus. Information provided through the research will be
helpful in the conservation of this unique creature since they are considered
as endangered and placed in Schedule I of the Indian Wild Life Protection Act,
1972 from July, 2001.
