Cephalopod fishery of Maharashtra State
Cephalopod fishery of Maharashtra State, if can be
inferred that as the demand is increasing,
over-exploitation due to increased fishing pressure
is possible, which may ultimately lead to stock
depletion. It is suggested that measures should be
taken at this stage for rational exploitation of this
important resource and therefore it is imperative to
evolve effective fishery management measures for
judicious exploitation
First record of cuttlefish Sepia (Doratosepion) kobiensis Hoyle, 1885 from the north-west coast of India
Cephalopods are caught mainly as by-catch in
the bottom trawl and due to the growing demand for
cephalopods in the international market, they are
exploited all along the Indian coast. In Maharashtra,
cephalopods are mainly exploited by shrimp trawlers
and stand second in the alll India production. The
main fish landing centres for cephalopods at Mumbai
are New Ferry Wharf (NFW) and Sassoon Docks.
Cephalopods contribute 10.6% towards the total fish
catch in Maharashtra (CMFRI, 2009
Note on the stranding of marine mammals on Chavakkad beach, Kerala
The observation of marine mammals from Chavakkad beach, Kerala is reported. On 16.03.2019, a carcass of finless black porpoise, Neophocaena phocaenoides (Fig. 1) was observed on Akkalad beach. The porpoise measured 95 cm in total length and being in highly decomposed state morphometrics could not be recorded
First record of the Oman cuttlefish, Sepia omani Adam and Rees, 1966 from Maharashtra waters
Many new records of cephalopods are reported
from Maharashtra waters over the years. A new entrant
of cuttlefish, Sepia omani Adam and Rees,
1966 (Fig. 1) was observed in trawl catches at New
Ferry Wharf, Mumbai. The depth of operation was
about 30-40 m at 70-80 km north of Mumbai coast.The
species was observed in the catch in April 2009. The
dorsal mantle length of the species landed ranged from
40 to 75 mm with corresponding weight ranging from
17.66 to 59.73 g. According to Jereb et al. (2005) the
maximum mantle length of this species is100 mm.The
occurrence of S. omani is reported for the first time
from Maharashtra waters
Rising trend in the fishery of the octopus Cistopus indicus (Orbigny, 1840) by trawlers at Mumbai
The world landings of octopus increased
substantially from 35,800 t in 1950 to 3,17,200 t in
2001 (Jereb et al., 2005). Major species of octopus
that contribute to the world fishery come under the
genera Octopus, Cistopus and Eledone. As many
as 200 species of Octopodidae are known to occur
in the world Oceans (Worms, 1983) of which about
60 are reported from the Indian Ocean (Roper et al.,
1984)
Various uses of cephalopods
Cephalopods were used to be treated often as part of discardable bycatches until recently, but it is no longer so. They now have an upgraded status because of their export potential, and their place as an important part of Indian marine products exports. In India over 80% of the landings of cephalopods take place along its west coast
Octopus fishery off Indian NW(Maharashtra)Coast
Octopuses, popularly known as 'Devil
fishes' are marine benthic animals found
to live from the sea coastal water down to
1000 m of its depth. The major species of
octopuses, which contribute to their global
fishery, come under the genera Octopus,
Cislopus and Eledone
First record of tawny nurse shark, Nebrius ferrugineus (Lesson,1830) from the north-west coast of India
Sharks contribute about 2% towards the total
marine fish landings in India and are fished mainly by
hooks and lines. They are also caught by gillnets,
trawls and purse seines as bycatch. Sharks are widely
hunted for flesh, liver oil and fins which are mostly
exported to south-east Asia.The species composition
of sharks in Maharashtra comprised of Scoliodon
laticaudus (86.2%), Rhizoprionodon oligolinx (3.9%),
Rhizoprionodon acutus (0.7%), Carcharhinus sorrah
(2.2%), Carcharhinus limbatus (1%), Carcharhinus
macloti (0.1%), Lamiopsis temminkie (2.6%),
Sphyrna lewini (2.2%) and Galeocerdo cuvier (0.7%)
Indian Scad, Decapterus russelli ....On its Fishery from Maharashtra Waters
