Abstract Life history parameters were determined for stranded and bycaught harbor porpoises ( Phocoena phocoena ) from Scottish UK waters (1992–2005). Fetal growth rate was 84.4 mm/mo mean size at birth 76.4 cm (range 65–88 cm). Males females had a similar range of body lengths (65–170 66–173 cm, respectively), although asymptotic higher in than males (approximately 158 147 respectively). Nonpregnant significantly lighter, relation to their length males. Maximum estimated age 20 yr both...
This study deals with important methodology issues that affect age estimates of eastern Atlantic bluefin tuna Thunnus thynnus using dorsal fin spines. Nearly 3800 spine sections were used from fish caught in the north‐east Ocean and western Mediterranean Sea over a 21 year period. Edge type marginal increment analyses indicated yearly periodicity annulus formation translucent bands (50% occurrence) appearing October to May. Nucleus vascularization seriously affected specimens older than 6...
Killer whale (Orcinus orca) encounters from commercial pelagic trawlers as well other types of vessels have been documented in several regions the northeast Atlantic; however, very little published information is available regarding such mackerel (Scomber scombrus) and herring (Clupea harengus) fisheries, waters between northern Scotland Norway. Mackerel are two main fish species targeted by Scottish fleet, primarily during October to March June September, respectively. Encounters with...
Abstract The blackfin tuna, Thunnus atlanticus , is a small tropical tuna exploited by recreational and commercial fisheries in various parts of its range. Information on stock structure needed to develop management plans for this species but currently lacking. In work, 470 from nine geographic populations were assayed at 13 homologous microsatellite markers provide first assessment across the overall divergence among locality samples was very low (overall FST = 0.0004) indicating high...
Abstract Age estimation in odontocetes is based on counts of growth layer groups (GLGs) deposited recording structures such as teeth. Generally, tooth sections are obtained using a cryostat microtome. However, some researchers prefer obtaining thin traditional paraffin Little information available the application this technique to dolphin Our main aim was investigate if can be viable alternative. We considered whether estimated age would affected by preparation technique, staining method,...
We examined the tooth ultra-structure of harbour porpoises ( Phocoena phocoena ) from Scottish waters to determine whether incidence mineralization anomalies could be related certain life history events (e.g. achievement sexual maturation) as well other factors that affect general health individual persistent organic pollutant (POP) concentrations in blubber). Five distinct types were recorded: accessory lines, marker dentinal resorption, cemental disturbance and pulp stones occurrence these...
Abstract The tooth histology of a total 22 and 95 short‐beaked common dolphins ( D elphinus delphis ) from S cottish UK G alician pain) waters, respectively, was examined to determine whether the incidence mineralization anomalies could be related certain stressful conditions linked with life‐history events or exposure anthropogenic pollutants (i.e. Polychlorinated biphenyls Dichlorodiphenyltrichloroethanes). Overall, five categories increased age. Model results indicated that presence...
The mineral component of fish otoliths (ear bones), which is aragonitic calcium carbonate (CaCO3), makes this structure the preferred sample choice for measuring biological carbon and oxygen-stable isotopes in order to address fundamental questions ecology fisheries science. main drawback that removal requires sacrificing specimen, particularly impractical endangered commercially valuable species such as Atlantic bluefin tuna (Thunnus thynnus) (ABFT). This study explores suitability using...
Twenty homologous microsatellite markers, or simple sequence repeats (SSRs), were developed for blackfin tuna (Thunnus atlanticus) through the use of a direct Seq-to-SSR approach.The number alleles per locus ranged between 5 and 26, expected heterozygosity 0.640 0.969.Three loci displayed significant departure from Hardy-Weinberg equilibrium expectations, likely reflecting occurrence null alleles.Another showed consecutive that differed by one base pair only.Consequently, this may be prone...
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...
Background Micromilled fish otoliths ( ear bones ) have been widely used for stable oxygen (δ 18 O) and carbon 13 C) isotope analysis. The first dorsal fin spine is routinely ageing in the eastern Atlantic bluefin tuna (ABFT) population; however, analysis remains unapplied this hard structure. objective of present protocol to achieve a sequential sampling growth layers ABFT at high spatial resolution along trajectory Methods We micromilling micro-powder collecting technique sequentially...
Marine wildlife and aquaculture species can accumulate large amounts of marine microplastic debris (MMD) (<1 mm) carrying pathogens, thus threatening the health ecosystems posing a risk to food safety human health. Here, we outline theoretical three-perspective approach for studying relationship between MMD disease. First, provide framework retrospective analysis pathogen loads in animal tissues assess these other environmental variables order decide whether compound or should be...
