Book Description
Striped catfish (Pangasianodon hypophthalmus) farming in the Mekong Delta, Vietnam, is considered as a major, aquaculture development both in Vietnam and globally. One of the main drivers responsible for the explosive growth of the sector is considered to be the development and commercialisation of techniques for artificial propagation of the species. This chapter looks first at the life-cycle of the striped catfish and historical developments in hatchery technology before going on to discuss induced breeding of catfish in hatcheries together with larval and fry nursing. Finally, harvesting and transportation are described and possible future directions in the sector.

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
Good water quality is of major importance to production results in a hatchery, particularly in those which work more intensively. A low cost water transfer system is also important economically, affecting both investment and running costs. The low cost, however, should not be allowed to compromise the efficacy of the system, leading to operating problems or a lower water quality, for example. This chapter will take a brief look at some important factors in the location of hatcheries, before progressing to assess different water supply systems, encompassing both fresh water and sea water. Before the water entersthe production unit, it hasto be treated to fulfill the requirement of the aquatic organism as closely as possible. A description of different water treatment equipment/methods is also included in the chapter.

Book Description
This chapter provides an update on the most common zooplankton live feed species used in hatchery rearing of fish and shellfish larvae, namely rotifers, Artemia and copepods. Each section starts with a summary of the biology and ecology of these species. An overview of the most common techniques to culture, feed, harvest, disinfect and preserve these organisms is provided. Special attention is given to nutritional and microbiological aspects. Furthermore, new trends and developments are discussed.

Book Description
This chapter deals with the different methods used in the world to produce hatchery-reared juveniles of Octopus vulgaris, including capture and transport methods, broodstock conditioning and paralarval rearing technology. First, a review is made of the different systems used for hatchery production of the various Cephalopod species in which there is the greatest commercial interest. Then, specifically for Octopus vulgaris, conclusions and standardized methods related to the spawning process, the control of embryonic development and, finally, a protocol for paralarval rearing are also given. The main bottlenecks and future research trends are pointed out, and important sources of further information and advice are referenced. A brief review of the state-of-the-art on larvae and juvenile rearing of other cephalopods species is also included in this chapter.

Book Description
To date, European mussel culture has relied entirely on wild seed from suspended collectors or mussel beds. One problem faced by blue mussel producers is the unpredictability of seed supply, the amounts of wild seed available being extremely variable from year to year. A second problem is that recently spawned mussels cannot be sold due to insufficient meat. Hatcheries can complement wild seed supply. Hatcheries also allow triploid induction that produces non-maturing mussels. In this chapter, the different steps in hatchery production of mussel seed are described. A final section addresses future trends.

Book Description
Sea cucumber fisheries have existed for centuries, driven primarily by the Chinese markets. In recent decades, overfishing has severely depleted commercial sea cucumber populations worldwide. Consequently, a growing number of countries are becoming interested in developing aquaculture programs. Every year billions of larvae and millions of juveniles are successfully grown in aquaculture facilities and new initiatives are booming. Here we introduce briefly the main species that have so far been successfully cultivated: Apostichopus japonicus, Holothuria scabra and Isostichopus fuscus. We describe common techniques for the culture of larvae and juveniles and outline some of the main challenges of this industry.

Book Description
Meagre (Argyrosomus regius) have good potential for aquaculture. Culture characteristics include controlled spawning in captivity, relatively easy larval rearing, fast growth, good feed conversion ratios and no maturation during ongrowing. Whilst characteristics of the final product include good processing yield, low fat content, good taste and firm texture. This chapter details the present knowledge on the biology of the species, the culture protocols being used through the entire production cycle (broodstock management, larval rearing, pre-ongrowing and ongrowing), product quality, market and economics of production. Finally future prospects and challenges to achieve mass production are examined.

Book Description
Global shrimp farming more than tripled production over the last decade. The major driver of that expansion was the introduction, adoption and expansion of farming P. vannamei as the shrimp species of choice. A key element determining farmers’ preference for P. vannamei was widespread availability of High Health post-larvae (PL) produced from specific pathogen free (SPF) broodstock that outperformed other shrimp species in reliability and profitability. Production of High Health PL requires use of SPF broodstock in hatcheries using biosecurity. This chapter reviews key management practices of securing SPF broodstock and biosecurity in P. vannamei shrimp hatchery systems.

Book Description
The hands-on nature of the hatchery setting is a natural supplement to curriculum units for students of all ages and experience levels. This chapter addresses the benefits of experiential education and provides descriptions of its use for a variety of aquaculture-based learning experiences pertinent to a number of subject areas. Recommendations for implementing such programs are presented for each grade level and discipline. The chapter provides a number of examples and resources to aid the reader in developing or enhancing instruction in the hatchery or classroom.
