The impact and control of biofouling in marine aquaculture: a review
The continued rise and expansion of the aquaculture industry and the increasingly stringent legislation for biocides in food production necessitates the development of innovative antifouling strategies which must meet environmental, societal, and economic benchmarks while effectively preventing the settlement and growth of resilient multi-species consortia of biofouling organisms.

To pre- vent escapes of juvenile and adult fish as sea-cage aquaculture industries develop, it is recommended that policy-makers implement a 5 component strategy.

It is suggested that coastal sea-cage fish farms may act as small (up to 160 000 m 2 ), pelagic marine protected areas (MPAs) at farms where wild fish are abundant and ecolog- ical interactions that may influence both wild fish stocks and the impact of farms must be considered.
Fish aggregation device (FAD) research: gaps in current knowledge and future directions for ecological studies
It is recommended that greater emphasis be placed by fisheries scientists and funding agencies on researching drifting FADs to provide better information for management of large-scale FAD-based industrial fisheries.
Salmon lice (Lepeophtheirus salmonis) development times, body size, and reproductive outputs follow universal models of temperature dependence

Water temperatures had a negative relationship with development times, adult body size, and reproductive outputs, except at 3 °C, where larvae failed to reach the infective stage and all parameter...
Coastal salmon farms attract large and persistent aggregations of wild fish: an ecosystem effect
Estimates indicate that salmon farms attract and aggregate over 12 000 t of wild fish into a total of just 750 ha of coastal waters on any given day in Norway, with possible consequences of these persistent, substan- tial aggregations of wild fishes at farms.
Network analysis reveals strong seasonality in the dispersal of a marine parasite and identifies areas for coordinated management

Seasonal variations in lice development times, oceanographic processes and the topological arrangement of salmon farms affect lice dispersal patterns, and a biologically meaningful and politically tractable alliance structure for sea lice management consisting of closely-associated clusters of farms is identified.
Seasonal patterns and diets of wild fish assemblages associated with Mediterranean coastal fish farms

Regional monitoring of farm-associated wild fish assemblages could aid management of the interaction of aquaculture and wild fish resources, because changes in feeding behaviour may have consequences for fish populations and local fisheries.
Aquaculture’s struggle for space: the need for coastal spatial planning and the potential benefits of Allocated Zones for Aquaculture (AZAs) to avoid conflict and promote sustainability
The need for coastal spatial planning, emphasis on the establishment of suitable areas for the development of marine aquaculture, is assessed, termed Allo- cated Zones for Aquaculture (AZAs), in which aquacculture has secured use and priority over other activities, and where potential adverse environmental impacts and negative interactions with other users are minimised or avoided.
