Do anti-parasitic medicines used in aquaculture pose a risk to the Norwegian aquatic environment? - Environmental Science & Technology (ACS Publications)

Do anti-parasitic medicines used in aquaculture pose a risk to the Norwegian aquatic environment? - Environmental Science & Technology (ACS Publications) | Aquaculture Directory | Scoop.it

Aquaculture production is an important industry in many countries and there has been a growth in the use of medicines to ensure the health and cost effectiveness of the industry. This study focussed in the inputs of sea lice medication to the marine environment. Diflubenzuron, teflubenzuron, emamectin benzoate, cypermethrin and deltamethrin were measured in water, sediment and biota samples in the vicinity of 5 aquaculture locations along the Norwegian coast. Deltamethrin and cypermethrin were not detected above the limits of detection in any samples. Diflubenzuron, teflubenzuron and emamectin benzoate were detected, and the data was compared the UK Environmental Quality Standards. The concentrations of emamectin benzoate detected in sediments exceed the environmental quality standard (EQS) on 5 occasions in this study. The EQS for teflubenzuron in sediment was exceeded in 67% of the samples and exceeded for diflubenzuron in 40% of the water samples collected. A crude assessment of the levels detected in the shrimp collected from one location and the levels at which chronic effects are seen in shrimp would suggest that there is a potential risk to shrimp. It would also be reasonable to extrapolate this to any species that undergoes moulting during its life cycle.

The significance of these findings will no doubt be disputed, but substantial use of pesticides in the marine environment is not desirable. It was good therefore to see the innovations from Aqua Pharma  in treatment delivery and control.at the recent Aquaculture UK exhibition.

Sustainability | Global Aquaculture Performance Index (GAPI): The First Global Environmental Assessment of Marine Fish Farming

Sustainability | Global Aquaculture Performance Index (GAPI): The First Global Environmental Assessment of Marine Fish Farming | Aquaculture Directory | Scoop.it
“Sustainable” is among the most sought after of all seafood product adjectives. Ironically it is also one of the most poorly defined and understood. The Global Aquaculture Performance Index (GAPI) is the first tool to assess environmental performance of global marine aquaculture production, permitting direct comparison of disparate species, production methods and jurisdictions. Clear patterns emerge from this analysis; significant variation of environmental performance is driven by the species being farmed, significant room for improvement exists across the entire sector, the worst performing players are also the fastest growing, particularly within Asia, and perhaps most importantly, this work highlights the potential trap awaiting policy makers who focus too narrowly on farm production efficiency alone as a solution to diminishing seafood availability.

There are many potential pitfalls and problems in creating an index of this type, but the approach should generate substantive discussion and promote greater understanding and development for everyone who engages with it: Good discussion starter or basis for an assignment for any aquaculture course
