Abstract Harvesting of underutilized mesopelagic resources
is among the possible solutions to increase capture
fish production, which will also facilitate recovery
of overexploited fish resources. Mesopelagics can be
a source for fish meal, which is in great demand
from the growing aquaculture and animal feed
industry and will find applications in areas like
nutraceutical and cosmetic industries. Recent estimates
based on acoustic data, put the biomass of
mesopelagic fishes between 11,000 and 15,000
million tonnes in the world oceans. Even though
there is a large potential for developing a fishery for
mesopelagics, very little information is available on
the appropriate commercial harvesting systems.
About 75% of total global catch of small mesopelagic
fishes is accounted by myctophids. Average world
annual production of myctophids between 1970 and
2015 has been 10,640 tonnes, with a maximum of
74,751 tonnes in 1990. Aimed midwater trawling
and pair trawling with appropriate trawl designs
have been considered suitable for harvesting mesopelagic
resources. An overview of the study is the
mesopelagics in the Indian Ocean and its availability
in the deep sea shrimp trawl bycatch. Sampling
gears and commercial fishing techniques targeting mesopelagics are discussed along with details of
experimental aimed midwater trawling conducted
in Arabian Sea, targeting mesopelagic resources.
