Download or read book Improving Penaeus Monodon Hatchery Practices written by and published by Food & Agriculture Org.. This book was released on 2007 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The successful farming of tiger shrimp (Penaeus monodon) in India is mainly due to the existence of some 300 hatcheries whose capacity to produce 12 000 million postlarvae (PL) annually has provided an assured supply of seed. However, the sustainability of the sector is still hampered by many problems, foremost among these being a reliance on wild-caught broodstock whose supply is limited both in quantity and in seasonal availability and that are often infected with pathogens. The current low quality of hatchery produced PL due to infection with white spot syndrome virus (WSSV) and other pathogens entering the hatcheries via infected broodstock, contaminated intake water or other sources due to poor hatchery management practices, including inadequate biosecurity, is a major obstacle to achieving sustainable shrimp aquaculture in India and the Asia-Pacific region. Considering the major contribution of the tiger shrimp to global shrimp production and the economic losses resulting from disease outbreaks, it is essential that the shrimp-farming sector invest in good management practices for the production of healthy and quality seed. This document reviews the current state of the Indian shrimp hatchery industry and provides detailed guidance and protocols for improving the productivity, health management, biosecurity and sustainability of the sector. Following a brief review of shrimp hatchery development in India, the major requirements for hatchery production are discussed under the headings: infrastructure, facility maintenance, inlet water quality and treatment, wastewater treatment, biosecurity, standard operating procedures (SOPS), the Hazard Analysis Critical Control Point (HACCP) approach, chemical use during the hatchery production process and health assessment. Pre-spawning procedures covered include the use of wild, domesticated and specific pathogen free/ specific pathogen resistant (SPF/SPR) broodstock; broodstock landing centres and holding techniques; broodstock selection, transport, utilization, quarantine, health screening, maturation, nutrition and spawning; egg hatching; nauplius selection; egg/ nauplius disinfection and washing and holding, disease testing and transportation of nauplii. Post-spawning procedures covered include: larval-rearing unit preparation, larval rearing/health management, larval nutrition and feed management, important larval diseases, general assessment of larval condition, quality testing/selection of PL for stocking, PL harvest and transportation, nursery rearing, timing of PL stocking, use of multiple species in shrimp hatcheries, and documentation and record keeping. Information on the use of chemicals in shrimp hatcheries and examples of various forms for hatchery record keeping are included as Annexes.

Download or read book Procedures for the Quarantine of Live Aquatic Animals written by James Richard Arthur and published by Fao. This book was released on 2008 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quarantine is an important risk management measure and a key activity that should be considered when developing national strategies for aquatic animal health management. It can also be used effectively to increase biosecurity at the farm production level. This manual outlines the technical requirements for setting up quarantine facilities at three levels, based on the general level of risk (as determined by risk analysis) represented by the specific consignment of aquatic animals being moved: (i) the quarantine of "high risk" species (e.g. aquatic animals being moved either internationally through introductions and transfers or domestically between regions of different health status that are destined for use in aquaculture, capture fishery development or other applications where release or escape of animals or any pathogens they may be carrying into the natural environment is likely to occur; (ii) the quarantine of "lower risk" species (e.g. aquatic animals destined for the ornamental trade) to improve biosecurity for aquatic animals whose trade is an established practice; and (iii) the routine quarantine of aquatic animals at production facilities (e.g. new, domestically produced or locally captured broodstock or juveniles or animals whose movement has been contingent upon additional, more stringent, risk management measures, such as the use of Specific Pathogen Free stocks, international health certification, pre-border and/or border quarantine, etc.). This manual should be useful to government policy-makers and responsible national and state agencies in assessing their need for quarantine capacity and in implementing aquatic animal quarantine in an effective and cost-efficient manner within the framework of national and state aquatic biosecurity programmes. It also provides useful guidance to responsible agencies, their technical staff and the private sector in setting up of effective quarantine facilities and their daily operation.

Download or read book Agriculture Diversification written by A. K. Sharma and published by I. K. International Pvt Ltd. This book was released on 2010 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Poverty continues to persist in many countries throughout the world despite improvements in the global trade regime and significant enhancement in agricultural productivity through the green revolution technologies. To achieve the millennium goal of halving poverty by 2015, these people should be provided with alternative production opportunities that can generate new employment and enhance incomes. Data from several countries reviewed in this study confirm that agricultural diversification can contribute to this. In a scenario of shrinking land and depleting water resources, the challenge of the new millennium is to increase biological yields to feed the ever-growing population without destroying the ecological foundation. It is thus important-not to package this challenge as a demand or imposition on farmers, for which they would bear the cost, but as a necessity and methodology to also sustain their welfare. This book deals with different practices in agriculture diversification. Care has been taken to include applied aspects and present scenario of different practices necessary for agriculture to the diversification. The book will be of use to the students, researchers and progressive farmers.
