Food utilization and surfacing activity of Channa striatus fry in relation to quality of food
Effects of food items (mosquito larva; pupa, ehironomous larva and chopped
pieces of the fish Lepidocephalichthyes thermalis) on food utilization and surfacing activity of
Channa Striatus fry were studied. Test individuals fed on live food organisms surfaced 94-
117% more frequent ly, consumed 23- 119% more ralions/day and, on an average, converted
33% more than those fed on pieces of Lepidocephalichthyes thermalis. Regardless of the
quality of food, Channa striatus surfaced about 60 times/h before each meal and the
frequency increased to 130 timesfh 3- 6 h after the meal was offered and returned to the
prefeeding level 18- 21 h after the meal
Gill net fishery off Veraval during 1982-1990
The fishery resources off Veraval are exploited intensively mainly by two gears, viz., trawl and gill nets. The gill net fishery has undergone changes by way of introduction of many out-board motorised canoes. Two types of crafts, wooden and FRP dugout canoes (with out-board engine) and plankbuilt boats are used for gill net fishing. Effort has remained almost constant during the 9 years. Fishes belonging to 10 groups formed about
98% of the gill net fishery
Fishery - Related Mortality of Sea Turtles in India: An Overview
Coastal communities have exploited sea turtles for centuries. In the 1950s, organised
fisheries were developed to capture turtles in many parts of the world; sea turtles were
considered an important exploitable fishery resource due to their high commercial value.
Turtle meat and eggs were seell as a basic protein source for coastal populations.
In India, Jacob (1973) highlighted the potential of sea turtle resources. Organised trade
in turtle products existed prior to the eighties (Dattatri 1984, Rajagopalan 1984, 2000).
It is estimated that 50,000-80,000 adult olive ridleys were captured off the Gahirmatha
coast every nesting season up to 1981-82 (Das 1985).
In September 1977. the five species of sea turtles that occur in Indian waters were
included in Schedule I of the Indian Wildlife (Protection) Act, 1972. As a consequence
of the implementation of regulatory measures, organised capture and trade decreased,
though illegal trade persisted till the mid-1980s. While the threat from targeted capture
and trade decreased, incidental capture of sea turtles in gear operated for other species
of fish and shellfish has become more significant over the years. The interaction of sea
turtles with fisheries has become an area of critical importance in many parts of the
world (Gerosa and Casale 1999, Vivekanandan 2002). In India tOO, incidental capture
in gill nets and trawls has become a serious threat to sea turtle populations (Rajagopalan
et a11996, 2001, Pandav and Choudhury 1999, Wright and Mohanty 2002). Due to an
increase in the number of fishing units, and also improvement in technology, incidental
bycatch has increased in recent years to the extent that it is the most significant cause of
sea turtle mortality in Indian waters
EPIDEMIOLOGICAL STUDY ON DIABETES PATIENTS ALONG WITH PATIENT INTERACTION AND COUNSELING
Objective: The main objective was to study the prevalence of diabetes and to create the awareness of the diseases among the peoples who visited and admitted in tertiary care hospital at Chennai.
Methods: This study was carried out at Sir Ivan Stedford Hospital in Chennai. The data were collected from the outpatient department of diabetology. In our study, 150 diabetes mellitus (DM) patients were selected, which include visited or admitted in the hospitals. The pilot study used to observe DM patient for 3 months and the outcome was recorded. As per the standard guidelines, patient data collection form was prepared and got approval from diabetologist for collected patient data and pharmaceutical care issues.
Results: A total of 150 cases were collected for this study. The epidemiological evaluation study has expresses that female patients were more when compared to male patients. The survey results indicate that 62 numbers are literate people and 88 of them are illiterate. As per the survey, the results indicate that the diet followers are 92 and non-followers are 58. The findings show that in patients doing exercise are more when compared to non-exerciser. The alcohol consumers show 42 of DM patients. The survey results show that 42 peoples are alcohol consumers and 46 peoples are smokers.
Conclusion: The survey on epidemiological study on diabetes patients demonstrated the prevalence of DM and the patientтАЩs adherence to diabetic care. In our study, we guided patients based on their diet and exercise through counseling. As a pharmacist, we render our services to patients
DESIGN AND EVALUATION OF COLON SPECIFIC DRUG DELIVERY OF BUDENOSIDE
Objective: The objective of this research is to design and evaluate a colon specific drug delivery of budenoside using guar gum as enzyme dependent polymer.Methods: Matrix tablets of Budenoside were prepared by using wet granulation technique with different proportions of guar gum and evaluated for different evaluation tests and release profiles.Results: The formulations were studied for post compression parameters like hardness, friability, weight variation and drug content are in acceptable range of pharmacopoeial specifications. In vitro swelling and Invitro release studies was carried out at different pH ranges (1.2, 6.8 and 7.4). The release profile of budenoside from the matrix tablets is dependent upon the gelling property of guar gum and degradation of guar gum polysaccharide by colonic bacteria. High concentration of guar gum showed less drug release in the stomach as an enzyme dependent polymer. In vitro release data revealed that the presence of rat caecal content in dissolution medium showed the significant increase in drug release (97.12%), when compared to drug release study in absence of caecal content (76.86).Conclusion: The results were subjected to study the release kinetics. The values of correlation coefficient indicated that the drug release followed Zero order drug release kinetics with Peppas drug release mechanism. In vitro drug release studies shows that guar gum with high concentration (25%) has optimum release in a controlled manner for 24 hours.├В
XANTHINE OXIDASE INHIBITORY ACTIVITY OF RHUS MYSORENSIS LEAVES
Objective: The objective of this study was to assess the in vitro xanthine oxidase (XO) inhibiting activity of the methanolic leaf extract of the Rhusmysorensis.Methods: Uric acid is synthesized in the presence of XO which is an essential enzyme. Various concentrations of the leaf extract were taken. XO inhibiting activity was spectrophotometrically assayed. By increasing absorbance at 295 nm, the degree of enzyme spontaneity was determined.Results: Inhibition concentration 50 (IC50) of the methanolic extract of R. mysorensis leaves was 45.24├В┬▒0.34 ├О┬╝g/ml, compared with IC50 value of the standard allopurinol of 7.8├В┬▒1.28 ├О┬╝g/ml.Conclusion: Methanol extract of R. mysorensis can be used to treat hyperuricemia and gout after proper preclinical and clinical studies
Some recent observations on small-scale fishery In the vicinity of Madras
Madras zone is one of the important fishing centres on the east coast of India. To understand the fish landings from different gears in Madras, three landing centres, viz., Kasimedu, Triplicane and Nochikuppam were selected. Kasimedu is about 8 km north of Triplicane and Nochikuppam is about 2 km south of Triplicane. The major catch components from the demersal trawls of this area arc silver bellies, threadfin breams, sciaenids, lizardfish, prawns, squids and cuttlefish. These groups are landed in a meagre quantity by the traditional gears, thus maintaining compatability between mechanised and non-mechanised gears in the exploitation of fishery resources off Madras

Recent Trends in Sea Surface Temperature and its Impact on Oil Sardine
The oil sardine is a coastal, pelagic schooling fish, forming massive fisheries in India. It has high population to doubling time of less than 15 months and is probably
the largest stock in the Indian Ocean (www.fishbase.org). Like many other small pelagics, the oil sardine also has shown pbpulation crashes and sudden recoveries in
the past. It is a tropical fish, governed by the vagaries of ocean climatic conditions. It is known for its restricted distribution in the Malabar upwelling region along the southwest coast. It attains a maximum total length of about 22 cm and plays a crucial role in the ecosystem as a plankton feeder and as food for large predators. The annual average production is 3.8 lakh tones (15% of all India total catch) valued at about Rs
350 crores. It is a cheap source of protein and forms a staple, sustenance and nutritional food for millions of coastal people
Ornamental shrimps collected from Kovalam, Chennai coast
During routine fishing operations with the hooks
and line by catamarans off the Kovalam coast,
fishermen lookout for floating debris, particularly
drifting woods and planks from river drainages during
floods, as these floating objects are associated with
large fish shoals of carangids, rainbow runners, tunas
and breams. These objects normally have algal
growth, Lepas colonies, barnacles, sponges,
ascidian colonies, sea spiders, amphipods and
several other associated fauna
