There is growing worldwide concern about bias in the enforcement of competition law in favour of domestic firms. Even seemingly neutral antitrust laws can lead discrimination if they are enforced selectively. - Authors investigate the distortions that national competition authorities generate when they pursue non-competition goals in favour of domestic firms, and discuss ways to address this negative policy development in a globalised world. - The distortions identified in the paper would dissipate if governments agreed that the sole objective of competition law ought to be the protection of consumer welfare that competition-law institutions ought to be protected against capture. - A realistic and effective way to prompt international convergence towards independent enforcement of competition laws is through the inclusion of competition clauses in bilateral trade agreements and the development of dispute-resolution mechanisms.

The influence of salinity, temperature and prey availability on the marine migration of anadromous fishes was determined by describing the movements, habitat use and feeding behaviours of Arctic char (Salvelinus alpinus). The objectives were to determine whether char are restricted to the upper water column of the inter-/subtidal zones due to warmer temperatures. Twenty-seven char were tracked with acoustic temperature/pressure (depth) transmitters from June to September, 2008/2009, in inner Frobisher Bay, Canada. Most detections were in surface waters (0-3 m). Inter-/subtidal movements and consecutive repetitive dives (maximum 52.8 m) resulted in extreme body temperature shifts (-0.2-18.1 °C). Approximately half of intertidal and subtidal detections were between 9-13 °C and 1-3 °C, respectively. Stomach contents and deep diving suggested feeding in both inter-/subtidal zones. We suggest that char tolerate cold water at depth to capture prey in the subtidal zone, then seek warmer water to enhance feeding/digestion physiology.
