Abstract The commercial fishery for Atlantic Sturgeon Acipenser oxyrinchus in the Saint John River, New Brunswick, began 1880. early was unregulated, and adult stock depleted by 1886 after landings of 712 metric tons. After a 10‐year closure reopened 1897 with management regulations, varied from 6 to 20 tons/year until 2010. In 2011 an annual quota 350 adults established are now stable at 11.3 ± 1.7 (mean SD) tons/year. Since 2009, fishers have collected biological statistics taken 14–60%...
Abstract As a long‐lived and late‐maturing species, Atlantic Sturgeon Acipenser oxyrinchus are susceptible to overharvest, which makes knowledge concerning their age growth essential sustainable management. The Saint John River, New Brunswick, the St. Lawrence Quebec, support two remaining commercial fisheries for in North America; however, relationship between has not previously been modeled River population. Ages of were estimated by using pectoral fin spine sections collected from 262...
Sea otters, Enhydra lutris (Linnaeus, 1758), forage in a mosaic of habitat types. The relative use heterogeneous environments by sea otters is largely unknown. Here, we examined whether foraging selectively habitats based on substratum grain size and/or prey availability. Use was determined the occurrence activity documented VHF radio-tagged and field collected data types prey. Selection for type comparing currently used vs available locations. We found that rocky to greater extent than soft...
Natural mortality of Atlantic sturgeon (Acipenser oxyrinchus) has been determined to be low (M = 0.07). Reported herein is the by beach stranding 11 in Scot's Bay, part inner Bay Fundy Nova Scotia, Canada on 22 June 2014. Genetic analyses, histological analysis and age determination were performed determine origin, maturity stage stranded sturgeon. Microsatellite mitochondrial DNA analyses indicated that four (2 males 2 females) from Saint John River, NB population, which was designated as...
Controversies remain regarding the periodicity, or seasonality, of otolith growth band formation, which directly influences a correct age determination Atlantic bluefin tuna using this structure. The aim work was to apply marginal increment analysis and edge determine timing deposition. index completion analyzed general additive models evaluate importance variables, such as month, age/size, reader. Results indicate that opaque formation begins in June is completed by end November. From year...
Thunnus thynnus (Atlantic Bluefin Tuna) is an opportunistic generalist predator in the pelagic zone of Atlantic Ocean. In northwest Ocean, Tuna diets are primarily based on small prey. Seabirds often prey same forage fish as tuna, leading to overlap timing and location both seabird foraging activity potential for tuna–seabird interactions. Here, we present first documented evidence consuming a Northwest This second report entire species' range. The this interaction comes from stomach...
