Temperature a Big Factor in Vibriosis, Photobacteriosis Outbreaks in Greek Sea Bass
European sea bass, commonly known as 'sea bass' in Mediterranean and European Union countries, is one of the most commercially important seawater fish species. This study, led by Georgios Bellos from the Agricultural University of Athens, looked at some...
Climate Change Vulnerability in Fisheries and Aquaculture
This report from the United Nations' Food and Agriculture Organisation (FAO) looks at six case studies of fisheries from around the world, and asks, how vulnerable are these regional industries to the effects of climate change?...
How to Maintain Good Water Quality on Your Tilapia Farm
Good water quality on tilapia farms depends on a suitable environment to promote growth. Such an environment can be achieved by maintaining the correct balance between feed input and the assimilative capacity of the water. However, the more fish that...
Water Quality a Priority for Successful Aquaculture
Water quality is very important in fish farming as poor quality water can effect the health and growth of the fish. It is important that farmers pay attention to the water's chemical and physical factors....
Polystyrene Nanoparticles Affect Fish Behaviour and Metabolism
Fish fed polystyrene nanoparticles are less active and show changes to their brains and metabolism, according to a study by Swedish and Danish researchers. The findings suggest that nanoparticles in the environment could have a major impact on fish...
Coastal, Fishing Lights Found to Alter Marine Ecosystems
Marine ecosystem composition can be changed by night-time artificial lighting from coastal communities, shipping and offshore infrastructure, according to new research....
World Governments Must Take Action to Protect Ocean Economy
Governments around the world must take action to safeguard the contributions of the oceans to the global economy, which are valued at $24 trillion, according to this report from the WWF: 'Reviving the Ocean Economy - The Case for Action - 2015'....

Can Natural Strategies Effectively Combat EMS?
Each year the shrimp industry suffers losses of more than US$1 billion due to early mortality syndrome or acute hepatopancreatic necrosis (EMS/AHPND), an emerging disease caused by the bacterium Vibrio parahaemolyticus. Pedro Encarnaçao, PhD and Jutta...
The Impact of Costal Acidification to the Aquaculture Industry
The aquaculture industry is undergoing a significant change, and one that presents a tough challenge to overcome. In Canada, fisheries along the west coast have been losing millions of pounds worth of stock and revenue due to the rising acidity of the...
How to Achieve Good Water Quality Management in Aquaculture
Water quality is the most important factor affecting fish health and performance in aquaculture production systems. Good water quality refers to what the fish wants and not what the farmer thinks the fish wants. This means that farmers must understand...
Water Quality Parameter Analysis for the Feasibility of Shrimp Culture
Muhammad Kasnir et al, Indonesia Moeslim University, Indonesia, carried out physicochemical studies to asses water resource in Mangara Bombang District, South Sulawesi in relation to their potential for shrimp aquaculture use....
Effects of Nitrite Exposure on Rabbitfish
Nitrite is toxic to fishes and is often encountered in recirculation aquaculture systems. Accordingly, the nitrite tolerance of potential aquaculture candidates needs to be assessed before the fish can be farmed in land-based recirculation systems. In...
Chronic Exposure to High Nitrate Concentration Reduces Growth and Affects Health of Juvenile Nile Tilapia in RAS
Due to nitrate accumulation during nitrification and low water-exchange rates in recirculating aquaculture systems (RAS), nitrate levels can build up. Hendrik Monsees has therefore investigated the effect that exposose to high nitrate concentration has...
Effects of Temperature, Digestion on the Swimming Performance of Juvenile Chinese Bream
To test whether digestion affected swimming performance in an active forager and whether the possible effects varied with temperature, Jing Peng et al, Chongqing Normal University, investigated the critical swimming speed (Ucrit) and the resting and active...
