Book Description
The book, "Practical Manual of Fisheries" is contemplated to fulfil the long standing needs to guide the fisheries work in field studies. The book starts with the standard statistical methods required to conduct fish culture experiments for testing a hypothesis and for presentation and interpretation of data. As a pre-requisite, evaluation and assessment of aquatic communities in a body of water, whether for experiment or for commercial fish culture is described in details, both for plant and animal communities, group wise as to the sample collection, preservation and quantitative and qualitative assessment. The fish, the ultimate end product is dealt in a separate chapter, highlighting the assessment of population, their behavior, method of collection and the bioassay techniques together with it application. The basic knowledge of fish anatomy and other physiological systems and their inventory is narrated in a chapter with the exception of fish embryology and reproduction of fish. Reproduction of different groups of fish and commercial fish breeding, methods of cultivation for optimum production is dealt in details. The knowledge on food and feeding habits of fish, various methods of analysis of their gut contents, determination of age and growth rate by examining scale and hard parts is given special emphasis in this regard. Investigations on the pollution of water bodies, the cause of fish diseases, their symptoms and prevention and control is discussed. The field study of fish population census, biological investigations of water bodies with regard to evaluation of their fish productive capacities, impoundment surveys and the creation of new fishing waters are described in details. Chemical water analysis essential for fish production together with the significance of each parameter is also mentioned in the book as a ready reconer. Special importance on the methodology on brackish water shrimp farming is given in the last chapter of the book. The manual will be useful to students, researchers and teachers in field studies.

Book Description
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.

Book Description
The cultivation of fish and shellfish larvae under controlled hatchery conditions requires not only the development of specific culture techniques, but in most cases also the production and use of live food organisms as feed for the developing larvae. The present manual describes the major production techniques currently employed for the cultivation of the major types of live food commonly used in larviculture, as well as their application potential in terms of their nutritional and physical properties and feeding methods. The manual is divided into different sections according to the major groups of live food organisms used in aquaculture, namely micro-algae, rotifers, Artemia, natural zooplankton, and copepods, nematodes and trochophores.
