Collection, transportation and stocking of fish seed
No full textThe collection of seeds from the wild is the main source to obtain the stocking
material for the cage. This can be carried out when the seed production cost is very high or
where the availability of seed from nature is in large quantity. It is important to know the
biology of the fish species either to duplicate reproductive condition on the farm or to know
when and where to collect the fish. The artificially produced seeds in the hatchery are used
widely in cage culture practice all over the world to avoid depletion of stock in the wild. The
transportation of the seeds to the culture site plays an important role as maximum mortality
occurs during this process because of change in metabolic pattern of the fish due to stress.
The appropriate quantity of seeds should be stocked in each cage for obtaining good
production. This chapter mainly deals with all these aspects in detail

Hazardous oil spill in Mumbai Port and adjacent fishing areas
No full textA catastrophic collision of two
merchant ships occurred in Mumbai
Port on 7th August 2010 which resulted
in spilling of about 800 t bunker oil and
tumbling of 293 cargo containers with
hazardous chemicals in the sea
Small scale targeted fishery for White sardine and Goldspotted grenadier anchovy along the Maharashtra coast
No full textIn Maharashtra especially in the suburbs of
Mumbai city (Versova, Cuffe Parade, Madh, Vasai,
Alibaug) an exclusive targeted fishery exists for
white sardine, Escualosa thoracata. This fishery has
been in existence for the past four decades and is
conducted by local fishermen. Locally this fish is
called Bhiljee due to its silvery-white shiny
appearance. Nearly 20-50 small motorized or nonmotorized
canoes (15-20 feet), small boats with
inboard/outboard engines (16-26 feet, 1-2 cylinder)
conduct fishing in the near shore areas (within 2-5
km) at depths of 2-8 m using special small meshed
(18 - 22 mm mesh size) drift gillnets called “bhiljee
jaal”. Length of the net ranges from 40 -100 m with
a height of 1.1 to 1.3 m. Each boat has a crew of
2 - 5 people. Each boat takes 8 -15 nets depending
upon the number of crew

Unprecedented landings of Indian Mackerel in Maharashtra
No full textUnprecedented landings of Indian
Mackerel, Rastrelliger kanagurta
was observed in Maharashtra during
October to December 2010. Estimated
catch of mackerel was 21,761 t that
contributed 18.2% to the total marine
fish landings of the state, replacing the
resource on the second position after prawns
in the order of abundance
Neoplasia in sawtooth barracuda
No full textSawtooth barracuda, Sphyraena putnamae is a
common species of barracuda in the pelagic fish
landings of Maharashtra. In 2015, 166 specimens of
S. putnamae (301-857 mm Standard length) were
collected from trawl landings at Sassoon Dock,
Mumbai and examined as part of routine,
specieswise biological studies on commercially
important marine fishes landed in Maharashtra for
developing the state's Fishery Management Plans.
On 9th December 2015, a single specimen of S.
putnamae measuring 685 mm in total length (TL)
and weighing 1.2 kg having neoplasia was found
among the sampled fishes
पिंजऱ्याची बांधणी : तत्त्व आणि आराखडा
No full textThe culture of finfishes in cages has been practiced for years in countries like
Cambodia, Vietnam, Indonesia, Thailand, Malaysia, Singapore and Hongkong. Cage was first
used as a holding facility for fish. True cage culture was said to have started in 1243 in China.
Use of modern cage materials like synthetic nets, woods and metals started in early 1960’s.
The size and shape of the cages are very important for the growth and production of the
fishes/ shell fishes living inside it. The design will vary depending on the selected site. The
constructed cage must withstand the force of wind and wave while holding the stock safely.
The cage must be safe, secure and easy to manage. Circular cage bags make the most
efficient use of materials, and thus have the lowest costs per unit volume. Shape is likely to
influence effective stocking densities and swimming behaviour, which in turn can influence
production. Fish cages can be constructed from a variety of materials. All materials used for
the cage should be durable, nontoxic, and rustproof
