Abstract The genetic structure of shrimp (Pandalus borealis) in the Northeast Atlantic was examined by RAPD analysis on specimens caught at eight stations in the Barents Sea, three off Svalbard, two off Jan Mayen, and in two northern Norwegian fjords (19 < n > 31 per station). A total of 34 polymorphic markers generated by seven 10-mer arbitrary primers was used to assess the genetic population structure using analysis of molecular variance (AMOVA). There was considerable RAPD diversity (>90%) among shrimp at all stations. The two Norwegian fjords and the Jan Mayen stations were different from all the others, and the Jan Mayen stations also differed from each other. More than 98% of the genetic variation between Barents Sea and Svalbard was ascribed to individual diversity, and there was no significant difference between the two areas, although there seemed to be a subpopulation structure in the Barents Sea. Principal component analysis on the frequency of each RAPD marker on each sampled station confirmed the presence of three populations: Barents Sea and Svalbard, northern Norwegian fjords, and Jan Mayen. We postulate that the large genetic variability found at an individual level may provide the total population with a diverse genetic pool from which traits can be selected to respond to variations in local environmental conditions, and that this local selection may be the cause of the subpopulation structure observed.

Abstract Durán Muñoz, P., Sayago-Gil, M., Cristobo, J., Parra, S., Serrano, A., Díaz del Rio, V., Patrocinio, T., Sacau, M., Murillo, F. J., Palomino, D., and Fernández-Salas, L. M. 2009. Seabed mapping for selecting cold-water coral protection areas on Hatton Bank, Northeast Atlantic. – ICES Journal of Marine Science, 66: 2013–2025. Research into vulnerable marine ecosystems (VMEs) on the high seas and the impacts of bottom fishing and ad hoc management measures are high priority today thanks to UN General Assembly Resolution 61/105. An interdisciplinary methodology (specifically designed for selecting cold-water coral protection areas) and a case study focused on the Hatton Bank (NE Atlantic) are presented. This interdisciplinary approach, developed under the ECOVUL/ARPA project, was based on conventional fisheries science, geomorphology, benthic ecology, and sedimentology. It contributes to defining practical criteria for identifying VMEs, to improving knowledge of their distribution off Europe's continental shelf, and to providing advice on negative fishing impacts and habitat protection. The approach was used to identify the bottom-trawl deep-sea fishery footprint on the western slope of Hatton Bank, to map the main fishing grounds and related deep-sea habitats (1000–1500 m deep), and to study the interactions between fisheries and cold-water corals. The results lead to a proposal to close the outcrop area (4645 km2) located on the western slope of Hatton Bank as a conservation measure for cold-water corals.

Summary The eggs recovered during faecal screening of Asiatic lions (kept at MC Zoological Park, Punjab, India) were delineated as Toxascaris leonina eggs based on morphometric and molecular studies (polymerase chain reaction targeting internal transcribed spacer sequences). Therapeutic management with fenbendazole @10 mg/kg body weight, once daily orally for three consecutive days proved ineffective with maximum faecal egg count reduction (FECR) on day 3 post treatments (69.35 %). But, therapeutic intervention with extended period dose schedule (5 consecutive days) with fenbendazole (@10 mg/kg body weight) proved effective and showed a maximum FECR of 95.34 % at day 7 post treatments. But, when ivermectin (@100μg/kg body weight) was given orally on three alternate days, proved effective as FECR of 95.74 % was recorded at day 7 post treatments. Thus, present study highlights the molecular confi rmation of T. leonina and its management using fenbendazole and ivermectin in Asiatic lions.
