By comparison with the vast sums of money involved in high-tech salmon farming the battle against parasites might seem like small fry, yet sea lice continue to elude modern eradication methods. Adam Anson, reporting for TheFishSite, finds out where the war is …
Saving water is an environmentally responsible goal, especially in the southeastern parts of the country, where droughts are fairly frequent, writes Sharon Durham, Agricultural Research Service Information Staff.
Born from the abstract philosophy of ecocentric ideals, aquaponics has emerged at the very frontier of agricultural technology. Yet, many years after the modern concept was first realised it has yet to receive the commercial recognition that might unlock its t…
Marine and large lake fisheries depend on the coastalarea in many different ways. A fisherys success is based uponcontinuing stocks of fish, which require healthy habitats for theirown food supplies and life cycles, reports the Food and Agriculture Organisatio…

As a second wave of Infectious Salmon Anaemia washes up on Scottish shores, the industry holds its breath. Only time will tell what gets upturned in its wake, but on a global scale the severity of the problem is already showing its true face, writes Adam Anson…
From the dark depths of the open oceans vast blooms of jellyfish are descending unforseen upon coastal waters worldwide, reports Adam Anson for TheFishSite. As the frequency of these invasions increases, the threat to both tourism and fisheries alike becomes e…

This guide from LaDon Swann, IIlinois-Indiana Sea Grant Program, Purdue University, helps fish farmers better understand the properties of water and how water quality effects fish culture.
By Michael P. Masser, Auburn University and published by SRAC, Oklahoma Cooperative Extension. In the US the majority of cage culture is practiced in ponds or quarries.
By Louisiana Department of Environmental Quality - Chapter 7 of the Louisiana Crawfish Production Manual. Poor water quality that persists for days and weeks isdetrimental to crawfish production.
By Fiskeriforskning - Water quality can be a limiting factor in achieving optimal growth and welfare of farmedcod. Fiskeriforskning has set focus on how water quality can affect cod in the larval and fry stages.
By Ruth Francis-Floyd and Craig Watson, University of Florida - Ammonia is a major metabolic waste product from fish. It is excreted across the gill membranes and in the urine. The primary source of ammonia in aquaculture systems is fish feed.
Tilapia is native to Africa and the Middle East. A decade ago, few people knew much about tilapia. Today, it has emerged to become the second biggest aquatic species group after the carp group, with a worldwide harvest of over 2 million metric tons (MT), about…
By Craig Tucker, Mississippi State University and published by the Southern Regional Agricultural Center and the Texas Aquaculture Extension Service - Fish, like all animals, must obtain oxygen from the environment for respiration. Oxygen is far less available…
By Sintef - Land-based aquaculture systems release water with high values of nutrients. Marine algae use most of these to produce biomass. This principle can be used to clean the water using chosen arts of algae and macro-algea in the effluent.
By John A. Hargreaves and Craig S. Tucker, Mississippi State University and published by the Southern Regional Agricultural Center and the Texas Aquaculture Extension Service - Dissolved oxygen concentration(DO) is considered the most important water quality v…

Low oxygen zones in coastal and open ocean ecosystems have expanded in recent decades, a trend that will accelerate with climatic warming. Christopher J. Gobler et al, Stony Brook University, US, experimentally assessed the consequences of hypoxic and acidifie…
Increases in atmospheric carbon dioxide drive accompanying changes in the marine carbonate system as carbon dioxide enters seawater and alters ocean pH. As such changes do not occur in isolation, and other environmental factors have the potential to modulate t…
