“…Such slow growth may be the trade-off for slower aging and stable or increased reproductive output in later life, as documented for fish (e.g. Atlantic cod, Olsen et al 2005; for a review see Pauly et al 2002) and for long-lived turtles (Congdon et al 2003). In both cases, older females increase reproductive output (egg production, clutch size or reproductive frequency) with age.…”

The ocean quahog Arctica islandica is one of the longest-living and slowest-growing marine bivalves. The oldest specimens obtained for the present study approached 200 yr. To achieve such a long lifespan, accumulation of oxidative damage markers in tissues must ideally be maintained at low levels over time, because the accumulating debris disturbs cellular functions. We investigated shell growth and cellular aging in an Icelandic population of A. islandica. Specifically, we analyzed protein carbonyl concentration as a marker for the oxidative deterioration of tissue proteins, and the accumulation of the fluorescent age pigment lipofuscin over quahog lifetime in gill, mantle and adductor muscle. The very slow growth rates of A. islandica correlate with very efficient maintenance of body proteins compared to other, faster aging bivalves. Lipofuscin granules accumulated mainly in connective tissues of gill and mantle. Lowest lipofuscin accumulation was found in the adductor muscle, and there, only outside the myofibrils. Consistent with the pleiotropic theory of aging, A. islandica seems to trade slow growth and late onset of reproduction for a very efficient autophagic potential that mitigates oxidative damage accumulation and supports long lifetime and presumably reproduction in very old ocean quahog.

Age at maturity is a key life‐history trait of most organisms. In anadromous salmonid fishes such as Atlantic Salmon (Salmo salar), age at sexual maturity is associated with sea age, the number of years spent at sea before the spawning migration. For the first time, we investigated the presence of two nonsynonymous vgll3 polymorphisms in North American Atlantic Salmon populations that relate to sea age in European salmon and quantified the natural variation at these and two additional candidate SNPs from two other genes. A targeted resequencing assay was developed and 1,505 returning adult individuals of size‐inferred sea age and sex from four populations were genotyped. Across three of four populations sampled in Québec, Canada, the late‐maturing component (MSW) of the population of a given sex exhibited higher proportions of SNP genotypes 54Thrvgll3 and 323Lysvgll3 compared to early‐maturing fish (1SW), for example, 85% versus 53% of females from Trinité River carried 323Lysvgll3 (n MSW = 205 vs. n 1SW = 30; p < .001). However, the association between vgll3 polymorphism and sea age was more pronounced in females than in males in the rivers we studied. Logistic regression analysis of vgll3 SNP genotypes revealed increased probabilities of exhibiting higher sea age for 54Thrvgll3 and 323Lysvgll3 genotypes compared to alternative genotypes, depending on population and sex. Moreover, individuals carrying the heterozygous vgll3 SNP genotypes were more likely (>66%) to be female. In summary, two nonsynonymous vgll3 polymorphisms were confirmed in North American populations of Atlantic Salmon and our results suggest that variation at those loci correlates with sea age and sex. Our results also suggest that this correlation varies among populations. Future work would benefit from a more balanced sampling and from adding data on juvenile riverine life stages to contrast our data.

“…Local effects include discharge of untreated effluents, spreading of aquatic animal pathogens and invasive species, and habitat alteration and related loss of ecosystem services. More global impacts involve release of greenhouse gases, unsustainable fishing behaviors in response to growing demand for fishmeal and fish oil, and, possibly also from an ethical and global resource management perspective, transformation of fish resources from human food to animal feeds (Naylor et al 2000;Pauly et al 2002;Klinger and Naylor 2012). Table 1 summarizes key environmental impacts of aquaculture production.…”

Eco-certification of Farmed Seafood: Will it Make a Difference?

Eco-certification is widely considered a tool for reducing environmental impacts of aquaculture, but what are the likely environmental outcomes for the world's fastest growing animal-food production sector? This article analyzes a number of eco-certification schemes based on species choice, anticipated share of the global seafood market, size of eligible producers, and targeted environmental impacts. The potential of eco-certification to reduce the negative environmental impacts of aquaculture at scale presently appears uncertain as: (a) certification schemes currently focus on species predominantly consumed in the EU and US, with limited coverage of Asian markets; (b) the share of certified products in the market as currently projected is too low; (c) there is an inequitable and nonuniform applicability of certification across the sector; (d) mechanisms or incentives for improvement among the worst performers are lacking; and (e) there is incomplete coverage of environmental impacts, with biophysical sustainability and ecosystem perspectives generally lacking.
