Description In the deep scattering layer (DSL) the fishes have accounted for 5.4 % of the
total (numerical) biomass. Juvenile fish belonging to different families were the most
abundant component followed by Vinciguerria, myctophids, leptocephali, stomiforms,
and unicorn cod. The "unicorn cod is represented by a single species,
Bregmaceros mcclellandi (2.4%) in the total fish biomass. It occurred in 52 stations
out of 445 IKMT stations. During day time the average number per haul was 21 where
as in night hauls it was 29. The resource was fairly abundant along the northwest coast
within the depth belt of 200 m. Biological studies on the size composition, feeding
habits, and reproductive biology of the species were also carried out. The length
ranged from 10-65 mm. The major diet consists of copepods, euphausiids, cheatognaths,
ostracods and decapod larvae. Invariably the feeding intensity was low. The
catch was composed of mostly females in maturity stages IV-V. The species spawns
only once in a year. The fecundity ranged from 530 - 980 in fishes of 42 - 50 mm in
total length.
