Environmental conditions influence ectotherm performance, resulting in natural intraspecific variation across geographic regions through local adaptation, developmental plasticity, or transgenerational phenotypic plasticity. Notably, blue mussels in particular locations in Nova Scotia (NS) experience elevated summer temperatures and exhibit a higher thermal tolerance relative to mussels from Prince Edward Island (PE), where temperatures are comparatively lower. This study aimed to assess the performance (growth and survival) of <i>Mytilus edulis</i> larvae using a fully factorial design between (1) source (NS vs. PE); (2) ploidy (diploid vs. triploid); and (3) thermal regimes (constant vs. fluctuating). Larvae were reared under a hatchery standard, constant 18°C or a semidiurnal fluctuating thermal regime of 16–20°C. After fertilization, eggs were either subjected to hydrostatic pressure shock to induce triploidy or placed directly into rearing treatments. Triploidy was confirmed using flow cytometry, and survival and growth were measured until settlement. This experiment found that (i) PE larvae had a larger mean length compared to NS larvae at 22 days postfertilization (dpf); (ii) PE larvae exhibited a higher triploid percentage; (iii) triploid treatments had lower survival and comparable mean lengths to diploid treatments; (iv) the fluctuating regime had no effect on survival or growth, but it diminished both the mean shell length advantage and triploid percentage of PE larvae; and (v) triploid percentage decreased under the fluctuating thermal regime. Future studies should investigate the mechanisms that explain differential performance across larval sources and explore effects in other life stages. These insights can serve as the foundation for producing climate-resilient blue mussels, thereby promoting the ecological and economic sustainability of the aquaculture industry.</p>","PeriodicalId":8104,"journal":{"name":"Aquaculture Research","volume":"2026 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/are/5066142","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147615342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, issues, such as farmed fish escape, closed-cycle farming, and nonstandardized breeding, have intensified inbreeding depression and germplasm degradation, necessitating an evaluation of escapement-induced genetic introgression and diversity loss in wild populations. We genotyped two cultured (Fujian [FJ] and Zhejiang [ZHJ]) and four wild (Qingdao [QD], Wendeng [WD], Yantai [YT], and Tianjin [TJ]) populations along China’s coast using a 40K SNP liquid array, obtaining 31,421 high-quality SNPs. Population genetic structure analysis revealed that all samples could be classified into three categories, with relatively distant genetic distances between groups. Genetic diversity assessment showed that all populations were moderately polymorphic, with observed heterozygosity (<i>H</i>_o) and expected heterozygosity (<i>H</i>_e) being relatively close, conforming to Hardy–Weinberg equilibrium (HWE). Notably, wild populations exhibited slightly higher genetic diversity than cultured populations. Population dynamic parameters—inter-population fixation index (Fst) ranging from 0.005 to 0.007, nucleotide diversity (<i>π</i>) from 2.108 × 10⁻⁵ to 2.177 × 10⁻⁵, and Tajima’s D from 2.172 to 2.207—collectively indicated that the populations have experienced genetic bottleneck effects or selective pressures, resulting in a small effective population size. Selective sweep analysis identified 57 core candidate genes from regions under positive selection. Functional enrichment analysis indicated that these genes are primarily involved in nervous system function, substance metabolism, cellular processes, and immune regulation. However, their expression patterns differed among populations, revealing that cultured and wild populations have developed distinct genetic regulatory mechanisms during adaptation to their respective environments.

However, there are several issues related to the environmental sustainability of shrimp CAS, including the widespread use of unsustainable construction materials such as plastic, concrete, and steel. One potential alternative material could be wood, which has been used in the food and construction industries for centuries. However, wood might contain high levels of extractives such as ketones, terpenes, and terpenoids. While some of these extractives may have beneficial properties for aquaculture, adverse effects have also been reported. Given this controversy, the objective of this study was to evaluate the effects of two wood species (i.e., Douglas fir and oak) on survival, growth, and feed conversion characteristics of juvenile PWS compared to a control group (i.e., fiberglass-reinforced plastic [FRP]) in a 42-day controlled randomized trial. Our results show that Douglas fir wood does not significantly alter shrimp performance compared to the FRP control. Conversely, the oak treatment resulted in partly significant inferior outcomes, which we attribute to the substantial leaching of detrimental wood extractives. These findings show that Douglas fir is a viable, eco-friendly alternative for shrimp aquaculture tank construction. Future studies should prioritize assessing the mechanical durability of wood-based systems over extended periods, perfecting pretreatment protocols to manage extractives, and investigating the capacity of shrimp populations to acclimate to natural wood environments. Applying these insights will facilitate the transition toward sustainable aquaculture by decreasing the industry’s reliance on synthetic materials.</p>","PeriodicalId":8104,"journal":{"name":"Aquaculture Research","volume":"2026 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/are/8342238","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147567635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their potential for nutrient utilization is significantly influenced by microalgae species, types of aquaponic plants, and growing conditions. This study determined the feasibility of co-cultivating microalgae species <i>Chlorella vulgaris</i> and <i>Scenedesmus</i> sp. and blue-green alga (cyanobacteria) <i>Spirulina platensis</i> in a Nile tilapia and garlic-based aquaponic system. Four aquaponic setups were operated in parallel for 8 weeks, with each setup replicated three times. Fifty juvenile Nile tilapia (initial weight: 9.94 ± 0.03 g) were assigned to 12 experimental tanks, with integrated floating raft plant beds, biofilter substrates, and continuous recirculation via submersible pumps. In the microalgae co-cultivated aquaponic water samples, key water quality parameters, particularly dissolved oxygen (DO), pH, and chlorophyll-a concentration, significantly improved. The chlorophyll-a concentration, an indicator of microalgal biomass growth, confirmed that the three microalgae species performed consistently well in each of the aquaponic systems. Microalgae co-cultivation significantly reduced the ammonia, nitrite, and nitrate contents compared to the control (ANOVA, <i>p</i>  &lt; 0.05).

In this study, a 500-L tubular photobioreactor (PBR) was evaluated and compared three control strategies—manual control, a programmed standard dilution control, and a proportional–integral (PI) control—for continuous cultivation of <i>R. salina</i> targeting a setpoint of 1 × 10⁶ cells mL⁻¹. A no-control experiment was first conducted to determine the carrying capacity of the PBR and establish the operational setpoint. The growth, cell yield, pigment content, fatty-acid composition, and inorganic nutrients were quantified across experiments. Incident irradiance was held constant (105 µmol m⁻² s⁻¹), while in-reactor irradiance varied with cell density (26–42 µmol m⁻² s⁻¹). Growth rates were comparable across control systems (0.25–0.33 day⁻¹), indicating that automation did not negatively affect microalgal performance. However, daily harvested biomass differed substantially: the PI control system yielded the highest production (1.27 × 10¹¹ cells day⁻¹), significantly exceeding manual control (5.33 × 10¹⁰ cells day⁻¹; <i>p</i>  &lt; 0.05), while standard dilution control produced the lowest yield (3.28 × 10¹⁰ cells day⁻¹). Both automated systems maintained stable cell densities with limited overshoot, though the PI controller exhibited moderate oscillations.

High mortality rates, cannibalism, and deformations continue to limit hatchery output and, by this, the economic efficiency for aquaculture endeavors with this species. Hereby, fatty acids (FAs), particularly polyunsaturated FAs (PUFAs), play a crucial role in larval development by influencing growth and a broad range of developmental processes. This study investigated FA pattern changes throughout key developmental stages from larval to juvenile pike perch. Hereby, a particular focus was placed on associations with growth and spinal deformation, as these are two major challenges in pike perch rearing. Comparing industry reared larval stages during grading, alongside maternal and dietary FA sources, shifts in FA composition were assessed. A consistent decline in long-chain PUFA (LC-PUFA) levels was observed. Shifts in the FA-profiles identified in larvae at 42–43 days post hatch (dph) marked a critical developmental window during metamorphosis. Although feed analyses confirmed a sufficient provisioning of FAs, findings suggests that higher LC-PUFAs intake may be required during this period. Phenotypic comparisons showed that FA-patterns of larger specimens are more closely resembling those of specimens with progressed developmental status. Deformation status, however, showed no significant connection to FA pattern variations, except for a tendency towards decreased saturated FA (SFA) levels during metamorphic stages, potentially reflecting elevated energy demands of deformed specimens. The consistently undetectable levels of mead acid (C20:3<i>n</i>−9) indicated a sufficient supply of essential FAs throughout the rearing period.
