Rearing of finfish and shellfish in cages and pens in water-based confinements is an
aquaculture technique which is gaining importance world-wide for intensive exploitation of
existing, especially large, fresh or brackish water and marine resources. The confined
aquaculture systems such as cages, pens or enclosures consist of growing of young fry of
finfish or shellfish to a large size, within netting or screening, which allows free circulation of
water. Enclosure is a confined bay, where shoreline is typically closed-off by a net or a screen
barrier on all but one side. The rearing facility in pen is almost man-made, the sides being
covered by bamboo-matting, netting or screening. The bottom in both, enclosures and pens,
however, is bound by lake bed
Diversity and distribution of cardinal fishes in Indian coastal waters with an occurrence report of spot fin cardinal fish Apogon queketti from Central south west coast of India
The family Apogonidae is a specious family with 346 species, in which most of them marine and some thrive in brackish water.
These are commonly referred to as cardinal fishes, which seldom reaches a maximum size of 20cm . Sixty five species of this family
have been reported from Indian waters. Apogon queketti is a valid species and two taxa have been synonymized with this viz.,
Apogonichthys queketti and Jaydia queketti. The genus Apogon which contains 108 valid species are mostly marine, living on sandy
and muddy bottom of the continental shelf
Open sea cage culture of marine fin fish and shell fishes in India

Bioactivities of extracts from the marine sponge Halichondria panicea
In the present study, we screened the biological activity of extracts from the marine sponge Halichondria panicea collected in the Arabian Sea. Crude toxin was obtained by methanol, chloroform-methanol (2:1) and aqueous extraction. Subsequently, the protein concentration of each crude extract was determined. The impact of both sponge methanolic and aqueous extracts was found to increase activities of Na+-K+ ATP-ase and Mg++ ATP-ase. In the case of chloroform-methanol extract, higher concentrations increased acetylcholine esterase (AchE) activity. The methanolic and chloroform-methanol extracts exhibited hemolytic activity on chicken and human erythrocytes, whereas the aqueous extract failed to do so. Methanol and aqueous extracts produced an immunostimulating effect and all extracts revealed angiogenic activity. The aqueous extract yielded nine bands by SDS-PAGE on 12% gel

Tripod fish caught at Sambhavi estuary, Mulky, Karnataka
During a regular seed survey at
Sambhavi estuary, Mulky on
30.05.2011, a short-nosed tripod fish (T.
biaculeatus) was caught in the cast net, which
operated at the depth of 1.5 meters. The total
length of the fish was 16 cm and the weight
recorded was 48 g
Length-weight relationships of ten tropical finfish species from north eastern Arabian Sea, India
The length weight relationships (LWRs) of ten tropical finfish species from north eastern Arabian Sea, India were studied. Specimens were caught using a wide range of fishing gear mainly trawl nets (20тАУ25 mm), dol nets or bag nets (20тАУ40 mm) and gill nets (80тАУ270 mm) operated in Maharashtra maritime waters during 2012тАУ2016. The specimens were measured for total length, and weight, then dissected and the sex confirmed. Previously unavailable in FishBase, the detailed LWR of Polydactylus mullani is reported for the first time. Maximum total lengths presented for six species in this study are new records. The existence of a differential growth between male and female was confirmed for five species, which was not known earlier. The LWR data will be useful for deriving future sustainable management and conservation strategies
Exploitation of the non-conventional bullseye fishery resource in Karnataka
The estimated average all India marine fish
landings during 2012-2016 was 36,71,651 t. Of late,
the catch of priacanthids has increased in
commercial landings all along Indian coast. The
bullseye contribution to the total production which
was 0.3% in 2011 increased to 3.6% during 2016 and
increased by two times from an annual average
23,031 t (2007-2011) to 45,544 t in 2012-2016.
Nearly 94% production was from the west coast
First record of Bull shark, Carcharhinus leucas (Valenciennes, 1839) in commercial landings from New Ferry Wharf, Mumbai, Maharashtra
A female specimen of big eye hound sharkIago
omanensis measuring 66 cm was landed at Mangrol
fishing harbor on 17th September 2013. The specimen
was collected along with 13 others of the same
species. I. omanensis was not recorded earlier from
Gujarat
