Spawning Areas

Protecting an area from fishing by establishing a sanctuary is one possible management strategy that could protect adults during spawning, potentially enhancing recruitment in freshwater systems. From 2001-2006, Briery Creek Lake (342 ha), Virginia was characterized by high fishing pressure in spring when adults were spawning and low abundance of age-0 Largemouth BassMicropterus salmoides. Therefore, we created two sanctuaries in 2006 in Briery Creek Lake that were closed to angling and boats; these areas provided protection for nest-guarding male Largemouth Bass. However, the nest-success rate did not differ significantly between open areas and sanctuaries (30-40% nest success). Catch per unit effort of age-0 Largemouth Bass did not differ between areas open to angling (28.8/h and 39.0/h in 2006 and 2007, respectively) and sanctuaries (14.6/h and 22.2/h in 2006 and 2007, respectively). Similarly, mean length-at-capture was not different for age-0 Largemouth Bass between sanctuaries and open areas. Closing spawning areas to fishing may not be an effective management option to increase Largemouth Bass recruitment success in Briery Creek Lake.

Per Se

AbstractAdults of Microtus agrestis, M. arvalis and Clethrionomys glareolus were offered the opportunity to explore an experimental alley, a section of which contained male odours of either of the three species. Neither of the species explored one of the sections of the alley more than the other one if the choice was between a section with conspecific odour and a non-odorous section. Both M. agrestis and C. glareolus preferred the non-odorous section when the choice was between M. arvalis odour and a non-odorous section. If an encounter with another vole was arranged in the alley before the opportunity was given to explore the partly odorous alley, then some additional avoiding responses to odours were assessed. M. agrestis now avoided both alien male conspecific odours and its own home cage odours. M. arvalis now avoided both the odours of C. glareolus and M. agrestis. Other responses to odours were not affected by an encounter. An encounter per se did not lead a vole to avoid the place where it had taken place. The survival value and the possible role of the avoiding tendencies in intra- and interspecific competition for space are discussed. Probably, odour avoidance is only an additional way in the communication between voles.

Hard Substrata

This work conducted during two seasons (May–October 1969, 1970) was designed to study the dynamic aspects of the settlement of benthic epifauna on hard substrata. The stations were distributed on a 200-km distance, the salinity gradient ranging from 15 to 27‰. Although over 60 species were identified on the plates, the analysis shows that only three of these are abundant: Polydora ciliata, Balanus balanoides, and Balanus crenatus. In general, the settlement period of the species is very short and most of the settling processes are concentrated in June, July, and August. The populations reached a peak of abundance during settlement and decreased regularly afterwards. This decrease is due mainly to intraspecific and interspecific competition for space, accumulation of sediment, and hydrodynamic factors in autumn. The marked physical seasonality of this subarctic environment, more than true biotic succession, is reflected in the development of the community: during the summer, the community is biologically accommodated, whereas in autumn and winter it is physically controlled.

Spatio Temporal

Pacific capelin Mallotus catervarius are planktivorous small pelagic fish that serve an intermediate trophic role in marine food webs. Due to the lack of a directed fishery or monitoring of capelin in the Northeast Pacific, limited information is available on their distribution and abundance, and how spatio-temporal fluctuations in capelin density affect their availability as prey. To provide information on life history, spatial patterns, and population dynamics of capelin in the Gulf of Alaska (GOA), we modeled distributions of spawning habitat and larval dispersal, and synthesized spatially indexed data from multiple independent sources from 1996 to 2016. Potential capelin spawning areas were broadly distributed across the GOA. Models of larval drift show the GOA’s advective circulation patterns disperse capelin larvae over the continental shelf and upper slope, indicating potential connections between spawning areas and observed offshore distributions that are influenced by the location and timing of spawning. Spatial overlap in composite distributions of larval and age-1+ fish was used to identify core areas where capelin consistently occur and concentrate. Capelin primarily occupy shelf waters near the Kodiak Archipelago, and are patchily distributed across the GOA shelf and inshore waters. Interannual variations in abundance along with spatio-temporal differences in density indicate that the availability of capelin to predators and monitoring surveys is highly variable in the GOA. We demonstrate that the limitations of individual data series can be compensated for by integrating multiple data sources to monitor fluctuations in distributions and abundance trends of an ecologically important species across a large marine ecosystem.
