Abstract A specific study has been carried out for the first time to investigate the homing capability and daily home range of the spiny lobster Palinurus elephas by means of ultrasonic telemetry. Nine lobsters collected in the Capo Gallo — Isola delle Femmine marine protected area (northwestern Sicily, central Mediterranean) were tagged with miniaturized transmitters and released at a single site inside the protected area. The lobsters were monitored with the purpose of calculating their horizontal and vertical positions, analysing their movement patterns to assess their homing capability, and calculating their daily home range. Five lobsters moved back close to the capture sites within the first 20 hours after release (‘homed’). The remaining four lobsters ‘relocated’ to a different refuge. Homed lobsters had a larger home range than relocated lobsters. This study provides the first description of a homing pattern with high spatial resolution in the wild European spiny lobster as inferred by ultrasonic telemetry.

Despite efforts to protect the resident Atlantic cod (Gadus morhua) population in Gilbert Bay, Labrador, its abundance has decreased since the area was designated a Marine Protected Area (MPA). As part of an effort to understand the reasons for the decline, tracking of cod tagged with surgically implanted ultrasonic transmitters was conducted to determine the migratory behavior of cod in relation to MPA boundaries. Acoustic tracking used a network of data-logging receivers deployed in Gilbert Bay and contiguous marine waters, permitting year-round monitoring of fish movements over several years. Acoustic tracking indicated that 93% of mature migratory cod >55 cm total length homed to the overwintering area where they were initially tagged. During summer months some individuals moved to the mouth of the bay and marine waters outside the MPA. Collectively, the home range of the Gilbert Bay cod encompassed an area within about 40 km of their overwintering and spawning site, but included a large area (∼270 km2) outside the MPA. Eleven percent of tagged cod released outside their home range returned to the capture site within 1 year after tagging. In contrast, fish transplanted 15 or 25 km from the capture site, but still within their home range, exhibited 100% success in homing, suggesting the importance of prior experience with the migration route for successful homing. This study documents the importance of knowledge concerning the migratory and homing behavior of resident fish populations for their conservation and management.

Abstract Ardron, J. A. 2008. Three initial OSPAR tests of ecological coherence: heuristics in a data-limited situation. – ICES Journal of Marine Science, 65: 1527–1533. As marine protected area (MPA) networks become established worldwide, it will be necessary to track the progress made in meeting the networks’ underlying ecological goals. The 12 coastal European nations of the OSPAR Convention have agreed to establish an “ecologically coherent” network of MPAs within the waters of the Northeast Atlantic by 2010. However, the meaning of ecological coherence has not been explicitly defined, and it has not been explained how it can be assessed. OSPAR’s work on this topic over the past 4 years is summarized here. As the 2010 deadline approaches, the urgency to assess ecological coherence increases. Proper scientific assessment is hampered by the current lack of detailed ecological data, and policy-makers are concerned that collecting data for indicators will tax already limited resources. Unconventional approaches that can make do with what little information is available are being developed, and three initial spatial tests are presented here. A personal perspective of lessons learnt is provided.
