Attraction and repulsion of mobile wild organisms to finfish and shellfish aquaculture: a review ArchiMer
Callier, Myriam; Byron, Carrie J.; Bengtson, David A.; Cranford, Peter J.; Cross, Stephen F.; Focken, Ulfert; Jansen, Henrice M.; Kamermans, Pauline; Kiessling, Anders; Landry, Thomas; O'Beirn, Francis; Petersson, Erik; Rheault, Robert B.; Strand, Oivind; Sundell, Kristina; Svasand, Terje; Wikfors, Gary H.; Mckindsey, Christopher W..
Knowledge of aquaculture–environment interactions is essential for the development of a sustainable aquaculture industry and efficient marine spatial planning. The effects of fish and shellfish farming on sessile wild populations, particularly infauna, have been studied intensively. Mobile fauna, including crustaceans, fish, birds and marine mammals, also interact with aquaculture operations, but the interactions are more complex and these animals may be attracted to (attraction) or show an aversion to (repulsion) farm operations with various degrees of effects. This review outlines the main mechanisms and effects of attraction and repulsion of wild animals to/from marine finfish cage and bivalve aquaculture, with a focus on effects on fisheries-related...

Analysis of Soil Nutrients and Organic Matter in organic and conventional Marine Shrimp ponds at Guaraíra Lagoon, Rio Grande do Norte State, Brazil Organic Eprints
Schober Lima, Juliana; Focken, Ulfert.
This study compares the soil nutrients from an intensive and semi-intensive and an organic marine shrimp farm located in Guaraíra Lagoon, Rio Grande do Norte State, Brazil. The organic system showed significant lower levels of organic matter and phosphorus when compared to the two conventional systems. The results indicate that the conventional systems release large amount of nutrients into the environment and the organic system is a sink of nutrients from the Guaraira Lagoon ecosystem.
Tipo: Conference paper, poster, etc. Palavras-chave: Farm nutrient management.
