Estimating blue mussel (Mytilus edulis) connectivity and settlement capacity in mid-latitude fjord regions

Communications Biology, Год журнала: 2024, Номер 7(1)

Опубликована: Фев. 9, 2024

Abstract The mussel industry faces challenges such as low and inconsistent levels of larvae settlement poor-quality spat, leading to variable production. However, farming remains a vital sustainable environmentally responsible method for producing protein, fostering ecological responsibility in the aquaculture sector. We investigate population connectivity larval dispersion blue mussels ( Mytilus edulis ) Scottish waters, case study, using multidisciplinary approach that combined genetic data particle modelling. This research allows us develop thorough understanding dynamics mid-latitude fjord regions, infer gene-flow patterns, estimate divergence. Our findings reveal primary south-to-north transport direction presence five clusters. discover significant continuous material exchange among populations within study area, with our biophysical model’s outcomes aligning observations. Additionally, model reveals robust connection between southwest coast rest west coast. will guide preservation ensuring contribute marine ecosystem health resilience.

A common garden experiment supports a genetic component underlying the increased resilience of common cockle (Cerastoderma edule) to the parasite Marteilia cochillia

Abstract The common cockle is a valuable bivalve species inhabiting the Atlantic European coasts. parasite Marteilia cochillia has devastated beds in southern Galician (NW Spain) rias since 2012. Previous data suggested that cockles from Ría de Arousa acquired some resilience to this through natural selection after consecutive annual marteiliosis outbreaks and candidate markers associated with were identified using population genomics transcriptomics approaches. Here, garden experiment was performed naïve stock (from Muros‐Noia) an affected Arousa) test hypothesis. Breeders both stocks used produce seed cohorts at hatchery, which pre‐grown raft (outdoor nursery stage) deployed two shellfish by (growing‐out stage). In beds, showed high prevalence fully depleted short period, while barely evidence of marteiliosis. A set 45 SNPs putatively fitted for MassARRAY genotyping check their role differential detected between stocks. Though no significant differentiation found neutral markers, 28 divergence them, suggesting these involved directional during eight generations (to most) pressure (long‐term selection). Furthermore, signals also along outbreak growing‐out stage (short‐term selection) six SNPs, all shared long‐term evaluation, consistent according infection severity. Some located within immune genes pertaining families such as proteasome, ubiquitin, tumor necrosis factor, glutathione S‐transferase. These resilience‐associated will be useful recover production Galicia.

Well-founded and supposed negative effects of cockle dredging on tidal-flat sediment and fauna: A review of contributions of ecological research

Journal of Sea Research, Год журнала: 2023, Номер 194, С. 102408 - 102408

Published studies on effects of mechanical dredging tidal flats for cockles (Cerastoderma edule) are critically reviewed, with special emphasis in the Dutch Wadden Sea. The evidence fishery-caused changes sediment composition is contradictory, but some loss silt and coarsening was found part fished areas. However, touched annually Sea invariably small (mostly only a few percent) recovery rapid. Generally, negative bivalve recruitment following fishing were not established. Negative non-target fauna always present variable. Recovery generally stocks adult thinned, high proportions caught minority years when cockle abundance low. Food supply shellfish-eating birds flats, notably Oystercatchers, reduced areas, seriously so most years. Evidence bird condition survival present, scarce. Such depended availability alternative food, particularly mussels (Mytilus edulis). Overall-negative reports consequences fishery published by group ecologists. These judged questionable. Though appear to be all bad as sometimes supposed reasons close this partly open question, resumption (since two decades forbidden) recommended.
