Diseases in ocean ecosystems and their dynamics in relation to climate change. In: Winter School on Impact of Climate Change on Indian Marine Fisheries held at CMFRI, Cochin 18.1.2008 to 7.2.2008

Existing and emerging pathogens pose unusual challenges to marine life, because of their potential to drive rapid changes in the numerical abundance and composition of host populations. Disease outbreaks, due to parasites (protozoans, crustaceans and helminthes) and microbial pathogens (bacteria, fungi and virus) alter the structure and function of marine ecosystems, directly affecting vertebrates and invertebrates. Although the important pathogens in terrestrial ecosystems have long been recognized and studied, the role of diseases in most marine communities is comparatively unknown and such studies are limited. Quantitative analysis of the scientific literature of the past four decades indicates a large increase in the number of reports about marine diseases in molluscs, corals, marine mammals, turtles and echinoderms (Kim et al. 2005; Table1). In this context, it would be of great importance to analyse the basis and timing of marine disease events and pathogen profile in relation to the major environmental events such as climate change. The ecological and biological impacts of diseases in the oceans remain largely unknown in spite of the negative impacts of diseases to the marine ecosystem

Relevance of disease management with special reference to sustainable fisheries and mariculture. In: Winter School on Impact of Climate Change on Indian Marine Fisheries held at CMFRI, Cochin 18.1.2008 to 7.2.2008

When the ability of the traditional food production systems such as a agriculture and animal husbandry has shown stagnation in the new millennium, India need to find alternative food production systems to feed the ever growing population. In this endeavour ‘aqua farming’ on land and farming in sea is to play a major role, considering vast potential of water bodies and seas of India, where fish farming can be practised. It is estimated that about 5 million tonnes of aquatic animal products can be produced annually through land based aquaculture in India, and the potential of seafarming could be many fold

Health management issues in the development of mariculture: an Indian perspective- Winter School on Recent Advances in Breeding and Larviculture of Marine Finfish and Shellfish

Achieving food safety in terms of valuable protein for the ever growing population of Indian subcontinent is a major challenge in the 21st century. In this endeavour ‘Aquafarming’ is to play a major role, as agriculture and animal husbandry has been slowing down in growth. The strength of Indian aquaculture lies in (a) large water bodies suitable for aquaculture, (b) tropical Climate, (c) species diversity and (d) availability of cheap labour. While the weakness include (a) unregulated development, (b) disease problems and (c) lack of scientific approaches. It is estimated that about 5 million tones of aquatic animal products can be produced annually through aquaculture in Indi

Conservation and management of marine fishery resources of Kerala State, India

The highly productive fisheries of Kerala, India, are suffering from overexploitation. Use of unsuitable fishing gears that result in a high level of wasteful bycatch and destruction of egg bearing and juvenile fish should be controlled. This paper makes some suggestions for monitoring and conservation of the fisheries in Kerala

Introduction to Exotics and Trans-Boundary Movement of Aquatic Organisms: Policy Requirements and Relevance to Indian Aquaculture in the Post-WTO Scenario

Aquaculture is one of the fastest growing industries with an annual growth rate of more than 11 per cent for the past 10 years, producing about 16 per cent of the world supply of animal protein, primarily for human consumption. FAO (2007) has estimated the production from aquaculture at 47.8 million tonnes in 2005 and the global aquaculture production in comparison has overtaken the global production of meat from bovine, ovine, porcine and poultry. Global aquaculture production has jumped from a mere 3.9 per cent of the food produced in 1970 to an impressive 47 per cent in 2006, which indicates a 10 per cent per annum growth. The Indian aquaculture sector led by shrimp and carp farming has recorded an impressive growth during the past decades, raising itself to the status of an industry and a major source of foreign exchange to the country to the tune of @15000 crores/year. The strength of Indian aquaculture lies in (a) large water bodies suitable for aquaculture, (b) tropical Climate, (c) species diversity and (d) availability of cheap labour. While the weakness include (a) unregulated development, (b) disease problems and (c) lack of scientific approaches and (d) non-compliance with guidelines and regulations

Diseases in Ornamental Fishes

Any impairment that interferes with the performance of normal funcrions including responses to environmental factors, roxicants, dimare, nutrition, infectious agents etc can be termed a disease. Diseases can be caused by a variety of factors, the most important being pathogens. Other factors contributing cowards the development of disease conditions include stress, environmental/water qualiry, physical agents, nutritional imbalance, toxins etc. or a combination of these

Relationship between lung inflammation, changes in lung function and severity of exposure in victims of the Bhopal tragedy

The world's worst chemical industrial disaster, which occurred at Bhopal on 2–3 December, 1984, resulted in considerable respiratory morbidity in the exposed population. Therefore, a study was planned to evaluate the relationship between lower respiratory tract inflammation, lung function and severity of exposure. Sixty patients exposed to methyl isocyanate and presenting with respiratory symptoms were studied using bronchoalveolar lavage (BAL) 1–7 yrs after the accident. Pulmonary function tests included forced vital capacity (FVC) and forced expiratory volume in one second (FEV1). An index of severity of exposure was derived retrospectively on the basis of the acute symptoms in the victims themselves or the occurrence of death among their family members. Total lung inflammatory cells (p<0.01) and absolute numbers of macrophages (p=0.01) and lymphocytes (p<0.05) increased as severity of exposure increased. FEV1/FVC % (p=0.05) was also significantly lower as severity of exposure increased. Moderately exposed subjects had significantly lower FEV1/FVC % (p<0.05) compared to those mildly exposed. In nonsmokers, BAL neutrophils, both percentage and absolute numbers, showed significant negative correlations with FEV1 % predicted (rs=-0.350, p<0.05; and rs= -0.374, p<0.01, respectively). Neutrophil percentage was negatively correlated with FEV1/FVC % (rs= -0.378; p<0.01). Absolute lymphocytes had significant negative correlations with FVC % pred (rs= -0.318; p<0.05). Macrophages had significant positive correlations with FVC % pred (rs=0.322; p<0.05) and FEV1 % pred (rs=0.433; p<0.01). Radiographic abnormalities (International Labour Organization (ILO) classification) were associated with decline in FEV1 % pred (p<0.05). This study suggests that pulmonary function abnormalities occur in gas-exposed subjects as a consequence of an abnormal accumulation of lung inflammatory cells (lymphocytes and neutrophils), and that the intensity of lung inflammation and reduction in pulmonary function are greater in severely exposed subjects. As it has been observed that decline in pulmonary function is associated with radiographic abnormalities, there is a suggestion that injury following toxic gas exposure can lead to irreversible lung damage
