Success in hatchery development of seabass and its potential for commercial cage culture in India

Brackishwater fish farming is considered as one of the potential areas not only as a source for fish production but also ensures the food security, livelihood for coastal community, business opportunity for entrepreneurs and also can earn foreign exchange. Coastal aquaculture has grown tremendously in early 1990s with farming of single species, the tiger shrimp Penaeus monodon. However, the shrimp farming faced severe set back due to outbreak of viral diseases coupled with social and other environmental issues. To overcome these issues, it is important to introduce some of the remedial measures in order to revive the aquaculture industry to achieve the sustainable production and one such measure clearly visible is the diversification of brackishwater aquaculture with fish species. It is evident that crop rotation can also decrease the risk of disease outbreak in the pond system

Impact of homestead farming system on rural economy: A study in South 24 Pargana district of West Bengal

Development of homestead farming system (HFS) has the potential for poverty alleviation in states like West Bengal since irrespective of the land holding size, most of the households in the coastal region of West Bengal, have a small piece of land adjacent to their dwelling where some kind of homestead farming is carried out using the indigenous knowledge. HFS is mainly a need-oriented, self- provisioning, integrated, multi-species, economically sustainable and environmentally safe farming system around the house where the soil is enriched by homemade biological formulations and integrated farming is undertaken. This system allows year round cultivation of different agricultural products (horticulture, aquaculture, timber, etc.)which can provide either a source of additional income to the households or function as an alternative livelihood especailly for the women members of the household. In order to understand the contribution of HFS to household income and to devise ways to maximise returns from HFS, a survey was conducted covering 480 households in three blocks (Kakdwip, Namkhana and Sagar) of South 24 parganas district of West Bengal

Prediction and management of natural disasters through indigenous Technical Knowledge, with special reference to fisheries

Traditional Indigenous knowledge has over the years played a significant role in solving several major social-ecological problems including those related to climate change and variability. People living close to nature often observe the circumstances around them and are the often the first to identify and adapt to any changes. The appearance of certain birds, mating of certain animals and flowering of certain plants are all seen as important signals of change with respect to timing and seasonality of natural phenomena that are well understood in traditional knowledge systems. Indigenous and local peoples have relied on biodiversity as a buffer against environmental variation, change and catastrophe

Status of Bioprospecting of Marine Molluscs in India

Continuous pressure on the environment arising inevitably or otherwise out of technological progress and human population growth has made it necessary to place a commodity value on biodiversity (Randall, 1991)

Employee Engagement: A Driver of Organizational Effectiveness

Employee engagement has emerged as a popular organizational concept in recent years. It is the level ofcommitment and involvement of an employee towards the organization and its values. An engagedemployee is aware of business context, and works with colleagues to improve performance within the jobfor the benefit of the organization. Employee engagement develops positive attitude among the employeestowards the organization. This paper focuses on various factors which lead to employee engagement andwhat should company do to make the employees engaged. Proper attention on engagement strategies willincrease the organizational effectiveness in terms of higher productivity, profits, quality, customersatisfaction, employee retention and increased adaptability.Key Words: Employee engagement, Organisational effectiveness, Productivity, Outcomes, Employeeretentio

Environmental Flow

Environmental flow defined as minimum flow that should be maintained in the river for the protection and maintenance of the environment as well as river morphology, ecology, aquatic life and pollution. Environmental flow is essential like blood circulation in human body. In this research 24 years daily discharge of lower part of the Mahanadi River are taken for the analysis. Analysis is based on two methods i.e. flow duration curve analysis method and range of variability analysis method. Flow duration curve analysis method includes 1-day, 3-day and 7-day flow. Range of variability of analysis method analyses by IHA (Indicators of Hydrologic Alteration) and calculates 67 statistical parameters (33 IHA, 34 EFC). Results obtained from both the methods are discussed

Genetic diversity and latency status of betanodavirus in wild seeds of Asian seabass Lates calcarifer (Bloch) sampled along Indian coasts

288-293Piscine nodavirus is the causative agent of viral encephalopathy and retinopathy in marine and freshwater fish worldwide. The present investigation was carried out to know the persistence and diversity of betanodavirus in wild healthy seabass seeds around east and west coasts of India from three major landing sites. The seeds obtained from two coasts were detected positive by nested PCR using RNA2 coat protein gene-specific primers. Phylogenetic analysis revealed all the three Indian coast sample sequences as close to Indian strain of betanodavirus reported earlier and those belong to red-spotted grouper nervous necrosis virus (RGNNV). These results indicate a strong latency or persistency of betanodavirus among wild healthy seeds of Asian seabass available along Indian coasts that remain as a source of viral inoculum for spreading disease in farm reared fish

A hospital-based study of severe anemia in adults in Eastern India

Background: Anemia remains a crucial health problem in developing countries. Cardiac compromise and fatal complications usually occur at Hb of <5g/dL. The aim of the study was to determine possible etiologic and clinical profile in adult patients with very severe anemia (Hb of <5g/dL).Methods: A prospective observational study was conducted in a teaching hospital of Odisha over a period of 12months. A total of 70 patients of both men and non-pregnant women admitted to the medicine wards were included after exclusion. Detailed history, clinical examination and investigation findings were recorded. Independent ‘t’ test, Wilcoxon rank sum test, Pearson chi-square test and Fisher exact test were used as applicable, to compare the variables.Results: The mean Hb (g/dL) was 3.73 ±0.85 and the mean age of the study group was 53.34±17.75years. No significant difference was observed in the severity of anemia between the female (mean Hb of 3.56±0.93) and male patients (mean Hb of 3.87±0.77) (p=0.130). The most frequent etiology found was absolute iron deficiency (44.3%, n=31) and mostly (41.9%) found in the age group of ≥65years (p<0.001). Congestive cardiac failure was found in 20% (n=14) of patients and majority of patients (64.2%, n=9) were males (p<0.001).Conclusions: Iron deficiency is the principal cause of very severe anemia in adults rather than malignancy or anemia of chronic disease and only about one fourth of patients develop heart failure even with very severe anemia
