India is one of the largest fish producers in the world and contributes 5.43% to global
fish production. India ranks second in fish production from aquaculture sector following
China at top. Total fish production of India during 2010-11 was 8.42 million metric tones.
Inland sector contributes about 5.2 million metric tones, whereas marine sector contributes
3.22 million metric tones. India has a long coastline of about 8,129 km and continental shelf
area of 0.5 million km2. Declining catch rates in marine capture fisheries consequently
created serious unemployment issues in rural coastal areas. Issues faced by marine fisheries
sector in India have focused the attention of policy makers and rural fishers towards
development of mariculture and coastal aquaculture activities as alternative livelihood option
Heavy landings of snappers at Mumbai with notes on the biology of Lutjanus argentimaculatus (Forsskal, 1975) and Lutjanus johnii (Bloch,1792)
Snappers are considered valuable seafood
delicacy and enjoy great demand in international
market. Snapper landings in Maharashtra have
increased over a period of time. The major species of
snappers landed in Maharashtra is Lutjanus johnii
which is accompanied by occasional landings of
Lutjanus argentimaculatus

The culture of marine finfish in cages was successfully initiated in Japan in 1950s and
in South East Asia during 1970s. In the initial years of cage culture, fish seed for culture was
collected from the wild. Recent developments in hatchery technology and seed production of
commercially important marine finfish and shellfish have ensured the continuous supply of
seed for mariculture practices. The disease control and health management are important
issues for sustainable aquaculture. The disease occurrence causes major economic loss to
aquaculture farmers. Production costs often increase due to disease outbreaks and treatment
procedures followed to overcome death of fishes during culture. In natural aquatic
environments, disease problems are unnoticed as diseased/weak/stressed fishes are easily
removed by predators and very few occurrences of disease outbreaks are reported. Moreover
in natural environment fish are not crowded as in captive culture conditions, which ultimately
causes stress in fishes frequently
Turtle conservation activities in Tambaldeg village, Sindhudurg district, Maharashtra
Tambaldeg village in Devgad taluka is a famous
tourist place in the Sindhudurg district. During a
field visit to Tambaldeg beach on 24th April 2017,
six carcasses of adult olive ridley turtle
Lepidochelys olivacea and one of green turtle
Chelonia mydas were observed in decomposed
state. This beach is a turtle nesting site and the
Forest department of Maharashtra with the support
of local fishers is undertaking awareness programs
for turtle conservation including hoardings
displayed on conservation of turtles along the
beach. Protection of nesting turtles and eggs is
also undertaken by the local communities
Report on morphological abnormality in Scylla serrata
Morphological abnormalities most commonly
reported in crabs are alterations in carapace (mainly
number and shape of antero-lateral teeth),
chelipeds, walking legs and shape of the abdomen.
Uran, a fishing village in Raigad district of
Maharashtra, supports a good fishery of Scylla
serrata commonly known as giant mud crab, found
in the coastal estuarine and mangrove areas
Observations on the fecundity of Rhynchobatus djiddensis (Forskal, 1775)
The resource is not targeted but is landed
as a by-catch. However, when compared to
1960s and 1970s the landing of R. rijiddensis
are very less indicating overfishing. As it is
included as a Vulnerable (VU) one in the mCN
Red list the fishes should be tlu'own back in to
the sea, if alive, as a conservation measure. There
is also a need to emphasise the need to conduct
the detailed maturity and reproduction studies
for better conservation practices. The
observations in respect of the fecundity of this
species in this contribution can be used as a
baseline data for further studies on the
reproductive biology of the fish which would
help in formulating a conservation policy
towards sustaining and conserving this specie
Heavy landings of threadfin breams at Sassoon Docks, Mumbai
At Sassoon Docks (new jetty), which is a major
fish landing centre in Mumbai, heavy landings of
threadfin breams were observed on 19th July 2011.
The catch was dominated by Nemipterus japonicus
and Nemipterus mesoprion
Marketing and economic feasibility of open sea cage culture

Plastic menace faced by fishers of Satpati, Maharashtra
Small conical stationary bag nets (Bokshi) are
operated by artisanal fishers mostly in creeks, with
strong tidal currents in certain regions of
Maharashtra. The net is set using wooden pole
(Khunt) driven at creek bottom against the flood
or ebb tide. At Satpati, Bokshi nets are operated in
the near shore creek for about 16 days in a month
at a rate of 2 hauls per day. Here, fishermen are
concerned about the increasing quantity of plastic
debris entering their nets during fishing operations
adversely affecting their livelihood

Sea farming is a popular area of aquaculture practice throughout the world. In Asian
countries, it is rapidly growing to meet the increasing demand of high value marine fishes.
Although India has a tradition of aquaculture, sea farming ventures on commercial scale were
lacking. In this context, Central Marine Fisheries Research Institute started open sea floating
cage culture activities in 2006-07 with Department of Animal Husbandry, Dairying and
Fisheries (DAHD&F), Government of India assistance. Indigenous cage of 15 m diameter
was fabricated following Norwegian open sea floating cage design and launched at
Visakhapatnam. There was a technical setback with the design of cage, and consultation with
Indian Institute of Technology, West Bengal helped to overcome technical issues with the
cage structure. Open sea floating cage diameter was reduced to 6 m and 14 new open sea
floating cages were launched at Sutrapada (Gujarat), Vasai (Maharashtra), Mangalore
(Karnataka), Cochin (Kerala), Pulicat (Tamil Nadu), Nellore, Kakinada, Baruva (Andhra
Pradesh) and Balasore (Odisha) in participation with National Fisheries Development Board
(NFDB)
