Fish cell lines and its applications for disease management in mariculture- Winter School on Recent Advances in Breeding and Larviculture of Marine Finfish and Shellfish

Fish cell lines have an important role in the expanding aquaculture industry of the world. The main impetus for the development of many of the continuous fish cell lines was to provide the means for isolating and identifying viruses that are the causative agents of epizootics of commercially important species. Cell lines are indispensable for development of precise diagnostics and prophylactics of the viral pathogens. Besides diagnosis, cell lines are important in the much required national and international quarantine and certification programme for producing virus free fish stock. Fish cell lines have also found widespread application in cytogenetics, transgenics, toxicology, as in vitro models for studying cellular physiological processes and also in comparative immunology

Nutrition and disease resistance in fish - Winter school on recent advances in diagnosis and management of diseases in mariculture, 7th to 27th November 2002, Course Manual

Outbreak of disease problems is a major concern and exerts heavy economic losses in fish farming as in any other farming practice. Aquaculturists are, therefore, interested in developing cost-effective management strategies that can either prevent the outbreak or reduce the severity of epizootics. Nutritional modification is one of the important management strategies currently under exploration. The inlluence that dietary factors may have on disease outbreaks in cultured fishes has been recognized since many years. In contrast to extensive type of farming systems where fish obtain all or part of their dietary nutrient needs from naturally available food organisms, fish in intensive culture conditions rely more on the provision of a nutritionally complete diet. Here, diet can have significant effects on disease resistance mechanisms and hence on infectious disease incidence and severity. A number of nutrients, mainly vitamins, minerals and fatty acids have been implicated in this regard

Hybridoma technique and monoclonal antibodies for mariculture applications

Ever since the beginnings of experimental immunology at the end of the nineteenth century, scientists have exploited the specificity of antibodies to detect, isolate and analyze biological material. The power of antibodies as probes for biological structure underwent a quantum increase in 1975, when Kohler and Milstein developed the technique for production of Hybridoma

Diseases of seabass in cage culture and control measures

The cage culture of finfish, especially marine cage farming is becoming more popular because of the many economic advantages associated with it. Though, operationally this has a number of advantages, the practice is vulnerable to natural hazards and can be affected by occurrence of diseases. Disease outbreaks can occur more often when fish are raised under intensive culture conditions and can pose problems in cage culture. Increased production under high density can create conditions conducive to outbreaks of infectious diseases and an increase in prevalence of parasites. Infectious diseases in fish culture are not only augmented by waste pollution, but exacerbated by crowding, handling, temperature and biofouling. The most common fish disease in cages is vibriosis caused by Vibrio spp. Furthermore, abrasions cause fin and skin damage to cultured stocks. Occurrence of infection/disease may be minimized by selecting good sites, proper mooring and observance of optimal stocking densities and careful handling of stocks

Mycotic diseases of fish and shellfish - Winter school on recent advances in diagnosis and management of diseases in mariculture, 7th to 27th November 2002, Course Manual

Several species of fungi are responsible for a range of serious economically important diseases offish and shellfish. However, far less is known about fungal diseases offish compared to bacterial or viral disease. Major problem is in identifying the fungus responsible and in determining whether it is truly pathogenic or simply a saprophyte taking advantage of an existing lesion

Biological aspects of the Sack fish, Neoepinnula orientalis from southeastern Arabian Sea

Biological aspects of Neoepinnula orientalis is reported based on samples collected from the by-catch landed by deep-sea trawlers at Cochin Fisheries Harbor. The estimated length at first maturity (Lm) of females was 195 mm and males 192 mm. Diet study indicated strongly carnivorous feeding habit dominated by fishes (55%), cephalopods (27%) and crustaceans (18%) occurring in deeper waters. Absolute fecundity ranged from 12,149 to 1, 54,556 with relative fecundity 737 eggs/g body weight and indicated a multiple spawning habit

Handbook of training programmes

The Indian Council of Agricultural Research has established specialised Trainers' Training Centres in order to meet the demand of adequately trained teachers and trainers in agriculture and allied subjects to impart training on the principles of learning by doing. The TTCs offer in-service training courses for the trainers/instructors of the extension training centres, agricultural schools and teachers dealing with work experience and vocational courses in high schools and higher secondary schools. In addition to these programmes, the TTCs also offer skill oriented training programmes to entrepreneurs and progressive farmer
