Ramachandran, A; Jameela Beevi, K S
While conducting surveys for potential ornamental fishes in the fresh water bodies
of the river Periyar, three specimens of Danio fraseri Hora and Mukerji, were collected from a
stream joining to the river Periyar, at Desom, near Alwaye on 6 October 2001. It is the only
species so far known under the genus Danio with a hypertrophied lower lip forming a loose
flap along the lower jaw. This is a new locality record for Kerala and southern Western
Ghats.

Ramachandran, A; Sankar, T V
Rays, belonging to the class Elasmobranchii, constitute a major fishery in many states in India
like Tamil Nadu, Gujarat, Andhra Pradesh, Kerala and Maharashtra. The estimated landings are
21,700 tonnes per annum. Even though the meat of rays is nutritious and free from bones and spines,
there is little demand for fresh meat due to the presence of a high urea content. The landings are
mainly used for salt curing which fetches only very low prices for the producers.
Urea nitrogen constituted the major component (50.8%) of the non-protein nitrogen of the
meat. An attempt has been made to standat-dize the processing steps to reduce the urea levels in the
meat before freezing by using different simple techniques like dipping the fillets in stagnant chilled
water, dipping in chilled running water and dipping in stirred chilled running water. It was found
that meat dipped in stirred running water for two hours reduced the urea level of the meat by 62%.
The yield of the lateral fin fillets and caudal fin fillets vary with the size of the ray. The drip loss
during frozen storage is found to be more in the case of samples frozen stored after the treatment for
urea removal by the method of stirring in running water. The samples treated in stagnant chilled
water had the lowest drip loss. The total nitrogen was higher in samples treated in stagnant chilled
water and lowest in the samples treated in stirred running water. The overall acceptability was high
in the case of samples treated with stirred running water and frozen stored

Ramachandran, A; Ramesan, M P
Result of the study on traditional traps in the inland waters of three northern districts viz,
Kasargod, Kannur and Kozhikode in Kerala state during 2003-2004 is presented. Mainly six
types of traps are found in operation. Chempally koode is a rectangular bamboo trap with"
D" shape in cross section operated without bait in some rivers of Kannur and Kasargod.
Bamboo screen barriers are almost completely replaced with durable HDPE net screen to
make handling easy. Thottil vala is a unique aerial trap operated from the dam in Pazhassi reservoir during monsoon to catch big fishes jumping against flowing water.

2008-01-01T00:00:00ZMarketing Channels in Ornamental Fish Trade in West BengalSoumya, Subhra DeRamachandran, Ahttps://dyuthi.cusat.ac.in:443/xmlui/handle/purl/41302014-07-19T20:30:33Z2011-06-19T00:00:00ZMarketing Channels in Ornamental Fish Trade in West Bengal
Soumya, Subhra De; Ramachandran, A
A lucrative export market and high domestic demand has made ornamental fish industry
in West Bengal a potential source for income generation. The study aimed to identify: (i)
the commercially important size groups of main ornamental fish varieties available in the
state; (ii) the existing supply chain; (iii) major constraints for development of the industry;
(iv) and to anlayse price spread of commercially important varieties; and (v) to evaluate the
profitability of operation at different stakeholder levels in the marketing chain. Export market
of ornamental fishes in the state followed a single supply channel while three different
distribution channels existed in the domestic market. High electricity charges was the major
problem faced by breeders (producers/rearers) whereas lack of technical knowledge regarding
transportation was the major constraint for wholesalers. Lack of knowledge on proper health
management inhibited the growth of retail industry. The fresh water catfish, angel, molly,
arowana, gold fish, tetras, and gouramis showed comparatively higher breeders’ share in
consumers’ rupee. Wholesalers were earning comparatively higher annual profit than the other
stakeholders due to moderate initial investment and also due to the comparatively lower
risk involved.
