Aquaculture: an introductory text

This 4th edition covers issues associated with sustainable aquaculture development, culture systems, hatchery methods, nutrition and feeding of aquaculture species, reproductive strategies, harvesting, and many other topics. While its main focus is on the culture of fish, molluscs and crustaceans for food, the book also covers other forms of aquaculture, such as the production of seaweeds, recreational fish and ornamental species, as well as live foods, such as algae and rotifers that are used to feed larval shrimp and marine fish. Thoroughly updated and revised, this essential textbook now includes increased coverage of open-ocean cage culture and sea lice issues with salmon culture, coverage of the significant progress made in nutrition, including the move away from fishmeal as protein and fish oil as lipids in feed, information on biofloc technology uses, predictive impacts of climate change, probiotics, and the impact of COVID-19 on the aquaculture community, and updated aquaculture production statistics and lists of approved anaesthetics. Aquaculture remains one of the most rapidly growing agricultural disciplines, and this book remains an essential resource for all students of aquaculture and related disciplines.

General fisheries commission for the Mediterranean: report of the webinar on the experience of the aquaculture sector through best practices and mitigation measures facing the COVID-19 crisis, 1 July 2020

This report presents the outcomes of the webinar on "the experience of the aquaculture sector through best practices and mitigation measures facing the COVID-19 crisis" which took place on 1 July 2020 and was conducted over the internet and hosted on the Zoom platform for webinars. It was organized by the General Fisheries Commission for the Mediterranean (GFCM) of the Food and Agriculture Organization of the United Nations (FAO) in cooperation with the Regional Commission for Fisheries (RECOFI). The webinar aimed to address the pandemic's effects on aquaculture production as well as on supply chains, demand, local markets and trade, and to identify best practices and mitigation measures adopted by aquaculture farmers and countries. During the first thematic session, the experts highlighted the difficulties the aquaculture sector faced due to the effects of the COVID-19 pandemic. Furthermore, several mitigation approaches were pointed out: (i) specific financial support programmes designed through the European Maritime and Fisheries Fund (EMFF);(ii) a strong national aquaculture strategy guaranteeing self-sufficiency along the entire supply chain of shrimp farming in Saudi Arabia;(iii) the issuing of subsidies and credit loans in a timely manner to help producers in Turkey;(iv) the development of an online platform for fish auctioning to boost fisheries supply chain in Oman;(v) companies opening direct communication channels between the government and the farms in the United Arab Emirates;and (vi) solidarity between the sector and consumers, which allowed for the achievement of 50 percent of the programmed goals in the fish feed and larval industry in Tunisia. Other points addressed during the second thematic session included specific measures adopted and proposed, such as the focus on different aquaculture final products (e.g. frozen fish) and the establishment of local hatcheries and fish feed factories. The Q/A session which followed concluded the webinar.

Optimisation of feed margins: as COVID-19 presents a real crisis for the aquaculture industry, it could also induce improvements in shrimp farming

This article describes the economic impact of COVID-19 to the global aquaculture industry and possible mitigation procedures to improve the supply, breeding and genetics, farming techniques, feed formulation, production costs, marketing and prices. The results of studies regarding the beneficial effects of proteinases on the growth performance and nitrogen digestibility and excretion in fishes and shrimp are also presented.
