On the oil sardine fishery of the Mangalore zone during the years 1957-1963.

In the Mangalore zone extending from Malpe to Kasaragod, the season for oil sardine [Sardinella longiceps Val.) is roughly the same as in the Calicut area, viz., October-March. Work on the fishery of this zone was started in 1957. - The first season's study was of a preliminary nature but later the programme was expanded to include detailed observations at Ullal, an important centre near Mangalore, and regular visits to other fishing villages for collection of samples. During this investigation special emphasis was laid on catch trends environmental variations and size and age composition. The results for the period 1957-63 are presented here. The fishery of part of this zone for the years1925-52 has been discussed by Nair (1952)

Observations on the Mackerel Fishery of the Netravati Estuary, West Coast, South India

The present communication relates to observations on an unusual fishery of the Indian Mackerel Rastrelliger kanagurta (Cuvier) in the Netravati estuary near Mangalore, lasting for about nine weeks from the latter half of January 1958. Normally the mackerel fishery is most active along the Konkan, Kanara, and Kerala coasts during the September-March period, and the catches comprise mostly immature forms ranging from 180-215 mm. in total length. There are no previous records of mackerel fishery of any appreciable extent from our estuaries, although Pradhan (1956) has recorded the fish entering the estuarine waters of the Kali River at Karwar

A note on the whale shark Rhincodon typus Smith, stranded off Mangalore

On the 5th March 1959, the trainees from the Fishery Training Centre were engaged in experimental purse seine fishing about four miles off Suratkal, an active fishing centre about ten miles north of Mangalore. At mid-day, during the low tide, they sighted a shark stranded in 2-3 fathom waters. Since the trainees were on a routine fishing trip they were poorly equipped for the capture of such giant fishes ; nevertheless, the shark was fastened with a two-foot hook in the caudal fin and in its struggle it dragged the two boats a few miles out into the sea. However, by evening it became exhausted, and next morning the dead shark was towed ashore

Stock assessment of pomfrets off west coast of India

 Pomfrets contribute 36 501 tonnes to the annual marine fish landings in India. Pumpus argenteus and Formio niger are the prime species forming 65.0% and 34.0% respectively of the pomfret catch. Gujarat and Maharashtrashare 42.6% and 35 9%of P. argenteus and 33.3% and 22.8% of F.nigerexploited, respectively. Thegrowth parameters for P argentew off Maharashtra and Kamatakaand MSY off Maharashtra (9 55 1 tonnes) and Kamatah (374 tonnes) were estimated. The results indicated high fishing pressure to the extent of 40% off Kanratalra. Large-scale destruction of young ones by do1 nets at Bessein (Maharashtra) resulted in I recruitment overfishing as the catches came down to 565 tonnes (1991) from 5 612 tonnes (1984). The growthparameters for F niger for Kerala and KarnataLawere estimated.MSY estimates were 1 055 tonnes off Kerala and 1856 tonnes off Karnataka.The effon needs to be reduced by 60%off Kamataka

A bibliography of parasites and diseases of marine and freshwater fishes of India

With the increasing demand for fish as human food, aquaculture both in freshwater and salt water is rapidly developing over the world. In the developing countries, fishes are being raised as food. In many countries fish farming is a very important economic activity. The most recent branch, mariculture, has shown advances in raising fishes in brackish, estuarine and bay waters, in which marine, anadromous and catadromous fishes have successfully been grown and maintained

Faculty promotions in medical institutions in India: Can we improve the criteria?

Research publications are desirable for academic promotion in medical colleges as per the current rules of the Medical Council of India (MCI). These rules reflect an endeavour to improve the academic standards. We strongly believe that every medical college teacher should conduct true research and contribute to good peer-reviewed publications. However, it is felt that the MCI rule has the potential to lead to undesirable consequences, and the quality of teaching and learning could take a back-seat. There is an urgent need to adopt more objective criteria and better guidelines as followed by well-known global institutes. In our own country, the University Grants Commission has formulated specific guidelines for this purpose in the form of Academic Performance Indicators which, it appears, are not taken into consideration by the MCI. This article discusses the adverse impact of the rule and suggests ways for the adoption of a more scientific assessment system for faculty appointment and promotion

Comparative evaluation of the hemodynamic effects of inclusion versus exclusion of dexmedetomidine to pregabalin and fentanyl premedication regimen during airway instrumentation in laparoscopic abdominal surgeries

Background: Airway instrumentation leads to an aggravated hemodynamic response due to increased sympathetic activity, imposing a risk of myocardial ischemia. A premedication regimen using fentanyl and pregabalin blunts the pressure response but not the rate response. Objective: To compare the effects of pregabalin and fentanyl regimen versus pregabalin, fentanyl, and dexmedetomidine regimen on the hemodynamic pressor response during airway instrumentation in laparoscopic abdominal surgery (LAS). Methods: Sixty patients (ASA I and II), undergoing elective LASunder general anesthesia, were randomly divided into 2 groups - Group A (n=30) premedicated with oral pregabalin (150mg) and IV fentanyl (2μg/kg) and Group B (n=30) premedicated with IV dexmedetomidine (0.25μg/kg) in addition to pregabalin-fentanyl regimen. Both groups were managed with the same anesthetic protocol. The preoperative sedation level was assessed before induction. The heart rate (HR), systolic and diastolic BP (SBP, DBP), and mean arterial pressure (MAP) were recorded at baseline as well as preoperatively, prior to intubation and at 1, 3, 5, 10, and 15 min after intubation. Results: Both groups had similar distribution of age, weight, gender, physical status, sedation level as well as intra-operative fentanyl and postoperative analgesic requirements.&nbsp
