Book Description
Aquaculture is the fastest-growing food production sector in the world. With demand for seafood increasing at astonishing rates, the optimization of production methods is vital. One of the primary restrictions to continued growth is the supply of juveniles from hatcheries. Addressing these constraints, Advances in aquaculture hatchery technology provides a comprehensive, systematic guide to the use of current and emerging technologies in enhancing hatchery production.Part one reviews reproduction and larval rearing. Aquaculture hatchery water supply and treatment systems, principles of finfish broodstock management, genome preservation, and varied aspects of nutrition and feeding are discussed in addition to larval health management and microbial management for bacterial pathogen control. Closing the life-cycle and overcoming challenges in hatchery production for selected invertebrate species are the focus of part two, and advances in hatchery technology for spiny lobsters, shrimp, blue mussel, sea cucumbers and cephalopods are all discussed. Part three concentrates on challenges and successes in closing the life-cycle and hatchery production for selected fish species, including tuna, striped catfish, meagre, and yellowtail kingfish. Finally, part four explores aquaculture hatcheries for conservation and education.With its distinguished editors and international team of expert contributors, Advances in aquaculture hatchery technology is an authoritative review of the field for hatchery operators, scientists, marine conservators and educators. - Provides a comprehensive guide to the use of technologies in enhancing hatchery production - Examines reproduction and larval rearing, including genetic improvement and microdiets - Discusses challenges in hatchery production of specific species

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
* Published in North and Central America by the American Fisheries Society. * Available exclusively from CABI Publishing in all other territories of the world. * Second edition of a leading fish culture manual * Relevant for both private and public fish culture * Vital as a training tool and as a day to day hatchery resource This second edition expands and updates the original Fish Hatchery Management, the preeminent fish culture manual, originally published in 1982, which has been used in universities and training centres to train new generations of culturists. The new edition has been completely rewritten by experts to include major advances in hatchery operation, in practical knowledge about raising high-quality fish, and in optimal use of cultured fishes in management programs. This up-to-date volume is greatly needed as a training tool and day-to-day hatchery resource. Like the first edition, the book includes a great deal of information about particular species, but its focus remains on the requirements and practical operation of culture systems. The new edition covers advances in production, water issues, transportation, stocking, open systems, controlled systems, semi-controlled systems, broodstocks and spawning, nutrition and feeding, fish health, and special considerations. Authors have developed chapters for relevance to both private and public fish culture.

Book Description
This manual is a synthesis of current methodologies pertinent to the intensive hatchery culture of bivalve molluscs. It encompasses both the similarities and differences in approach in rearing clams, oysters and scallops in different climatic zones. All aspects of the culture process are described, together with basic considerations in choosing a site for hatchery development and in the design of a suitable facility. It also includes the post-hatchery handling of larvae in remote setting and also of spat in both land- and sea-based nurseries. This document is intended to assist both technicians entering the field as well as entrepreneurs researching investment opportunities in bivalve culture.

Book Description
Induced Fish Breeding: A Practical Guide for Hatcheries takes a successive approach to explaining the use of breeding technology with proven scientific methods. It provides real-life examples for the purpose of maximizing fish and seed production to support overall sustainability in aquaculture. It is a concise reference to understanding the latest developments in the field, useful for anyone who is involved in fisheries or hatchery management as well as researchers and students who need to understand the technology. A practice originally developed to produce quality seed in captivity, induced breeding has made great strides in fish populations for India. The book offers a practical and succinct overview—from existing methods and operations to recent trends and their impacts on aquaculture for the future. - Provides detailed information about empirical breeding practices like mixed spawning and indiscriminate hybridization - Presents the environmental and hormonal influence on maturation and spawning of fish with real-life fish breeding examples from around the world - Includes step-by-step scientific measures to help solve problems arising from common fish-farming mistakes - Provides real-life examples for the purpose of maximizing fish and seed production to support overall sustainability in aquaculture
