“…Females were predominantly found deeper than 40 m, experiencing lower water temperatures than the males, the latter being commonly found as shallow as 30 m before the first water exchange event (i.e., the 4th of June) and after the deeper parts of the fjord started to cool (i.e., early October). Sexual segregation in RKC has previously been reported (Stiansen et al, 2009;Falk-Petersen et al, 2011), but research data supporting the existence of such behavior is rare (Stone et al, 1993;Taggart et al, 2008;Sundet and Hjelset, 2010). Mating is known to occur in shallow waters during springtime (e.g., Stone et al, 1993;Sundet and Hjelset, 2010).…”

Space and Habitat Utilization of the Red King Crab (Paralithodes camtschaticus) in a Newly Invaded Fjord in Northern Norway

The red king crab (RKC, Paralithodes camtschaticus) was introduced to the southern Barents Sea in the 1960s with the aim to develop a new, commercially attractive stock of the species. In the subsequent decades, the stock has indeed become abundant and widespread, but the species’ presence also implies intense predation on benthic biota and thereby severe degradation of benthic ecosystems. Our capacity to monitor and harvest the species efficiently is therefore imperative. Yet, fishermen report highly variable catches despite little variation in the timing and location of fishing, possibly induced by the species’ migratory behavior, which makes the search for crab aggregations time consuming and expensive. Previous studies have shown that the RKC is capable of conducting long-distance migrations, and suggest that the species conduct seasonal migrations between shallow (winter- and springtime) and deep waters (summer and autumn). Here, we applied telemetry to investigate the migratory behavior and habitat utilization of 37 adult individuals of the RKC in a relatively shallow fjord in northern Norway from late May until early November. Approximately half of the crabs (n = 16) left the study area early during the study period, but some individuals (n = 3) were recaptured between 53 and 147 km away from the study area, confirming that the RKC may conduct long-distance migrations. In contrast to expectations, most of the remaining individuals of RKC (n = 16) stayed for a prolonged summer and autumn period and used a limited portion of the fjord. These crabs responded quickly to changes in ambient water temperature, seeking deeper and colder waters masses when the temperature in shallower waters increased. Several individuals showed nearly identical spatio-temporal distributions, which supports earlier observations of crab aggregations. Our data indicates that the area utilization of the RKC is affected by trade-offs between biotic and abiotic factors, in which sub-optimal water temperatures may be tolerated provided appropriate access to food. Thus, our findings suggest that the current knowledge of RKC seasonal migration patterns may need to be revised, which in turn will have implications for managers and the fishing industry. This study demonstrates the high potential of telemetry studies to yield new, high-resolution data and knowledge of species’ ecology.

“…Recently the interest in movement patterns of commercially valuable species has become a crucial focus for both conservation and fishery management purposes (Gell & Roberts 2003). The efficacy of marine protected areas and restocking initiatives is heavily dependent upon such movement-related aspects of animal ecology and behaviour as home range, habitat use, homing and site fidelity (Taggart et al 2008;Green & Starr 2011;O'Toole et al 2011). In fact, movement patterns deserve major attention because they have an effect on the permanency and distribution of mobile species inside and outside managed areas.…”

This paper presents the results of the application of an ultrasonic telemetry system to the investigation of short‐term movements in the European spiny lobster, Palinurus elephas, in a coastal area of NW Sicily (Central Mediterranean Sea). Ten lobsters were tagged with miniaturized transmitters and released over a favourable habitat and their movements then recorded by means of nine automated receivers with the objective of investigating post‐release displacement, home‐range extension, movement patterns, activity rhythm and the influence of lunar light intensity on lobster activity. Acoustic detection data were used to assess activity and home range using estimates of horizontal and vertical movements and minimum convex polygons, respectively. Continuous wavelet transform (CWT) analysis was applied to time series of position data. Acoustic data from five of 10 lobsters were successfully recorded across a 78‐day study period between April and June 2008. All of them displayed an activity pattern characterized by diurnal sheltering and nocturnal foraging, with higher activity (i.e., longer distances travelled) at night. Their home range measured between 1629 and 8641 m2, and all lobsters relocated every 4.6 days on average, probably in search of unexploited feeding grounds. For this reason we hypothesize a nomadic movement pattern for our tagged lobsters. CWT analyses highlighted a 24‐h periodicity in lobster activity, with higher activity from sunset to sunrise. No clear influence of moon phase on lobster activity was detected.
