Summary: This study used acoustic biotelemetry to evaluate the feasibility of restocking hatchery-reared adult dusky groupers in no-take areas of a Portuguese Marine Protected Area. The results showed that none of the tagged groupers settled in the no-take areas, instead leaving mainly at dusk and night. Some individual groupers exhibited extended movements along the Portuguese coast, which is unusual for this species.

Summary: Successful stock enhancement programs aim to maintain economic profit while minimizing negative genetic and ecological effects. In the case of black rockfish, a stock enhancement program in the Liaodong peninsula showed positive economic performance with a resource contribution rate of 39.30%. However, potential genetic introgression from hatchery-reared individuals should be a concern. The hatchery-reared fish showed good adaptability, but exhibited some differences in size and morphology compared to wild individuals.

Summary: The study found that white-winged scoters and surf scoters have declined by over 60% in recent decades. Research indicates that pollutant accumulation has varying impacts on the nutritional status of white-winged scoters and surf scoters. Novel statistical methods reveal that liver mercury and selenium can explain 25% of the variance in nutritional status of white-winged scoters, while Cd, Hg, and Se in tissues can explain 14 to 27% of nutritional status in surf scoters.

Summary: The article "Diversity and Importance of Kelp Species in Puget Sound Waters" discusses the widespread distribution of kelp species in Puget Sound, providing numerous ecosystem services; however, there has been documented loss of bull kelp forests, posing a threat to marine ecosystems and jeopardizing economic activities. Despite the recognition of the need for action in the recently released Kelp Conservation and Recovery Plan, local environmental regulations may complicate restoration efforts and fail to adequately protect kelp. Through content analysis of 45 local Shoreline Master Programs, the assessment reveals generally low levels of kelp protection and support for restoration.

Summary: In complex social-ecological systems, environmental governance involves multiple actors and institutions interacting across scales. This study in the Puget Sound, USA, explores how actors in local collaborative organizations share and utilize scientific information, revealing patterns in horizontal and vertical information sharing, the role of knowledge brokers, and scale mismatches. The use of scientific findings by local collaborative organizations depends on the biophysical and political context, with tension between scientific rigor and local applicability.

Summary: Temperate rocky reefs support diverse habitats including macroalgal forests, algal turfs, and sea urchin barrens. The composition of epilithic microbial biofilms (EMBs) plays a crucial role in macroalgal recruitment, but their role in regulating the stability of alternative habitats remains unknown. A study on shallow rocky reefs in the Mediterranean compared EMB structure in different habitats under ambient and enhanced nutrient levels. Results showed distinct microbial communities in different habitats, with moderate nutrient enhancement having minimal effects on EMBs. Understanding the role of EMBs in habitat stability and reverse shifts is important.

Summary: This study aimed to investigate the relationship between microbial community profiles and gill pathology during a production cycle of Atlantic salmon in two commercial hatcheries. The relationships between gill histology, environmental conditions, and microbiome were determined using high-throughput data, and it was found that the commensal community of gill bacteria was related to melanin prevalence under commercial conditions.

Summary: Many salmonids are threatened or endangered, with habitat loss likely responsible. Hatcheries have been used to mitigate wild population loss, but differences between hatchery-origin and wild fish can confound research results. The Wild Fish Surrogate Program aims to produce juvenile fish more like wild Chinook Salmon for research through alternative rearing tactics. The program successfully generated target wild fish phenotypes, including smoltification and movement, with similar body shape, larger and more symmetrical fins, and less aversive behavior compared to hatchery fish. The program can be extended to other systems with endangered populations and help improve mitigation efforts or hatchery programs.

Summary: This study describes the shell color polymorphism and its corresponding metabolic activities in hatchery-reared Pinctada maxima juveniles. Yellow-colored shells exhibited higher enzymatic activity and showed less similarity to other colors of shells. Green-colored shells had comparatively higher levels of enzymes known to promote fast growth.

Summary: This study evaluates the capability of bivalves to reflect compositional variation in infaunal macroinvertebrate fauna. The results show that bivalves are effective surrogates for the entire fauna, with genus- and family-level data consistently strong substitutes for species-level data. The congruence between death assemblages and living bivalves is encouraging for using bivalve dead-shell assemblages in complementing monitoring data.

Summary: The study explores the relationship between feeding rate and relative competitive ability of 1-year-old and 2-year-old steelhead in hatchery tanks, finding that ration directly affects feeding rate and that ration and relative competitive ability interact to influence feeding rate. Older steelhead are more likely to be detected at a single feeding location, while younger fish are more likely to be detected at both locations.

Summary: Steelhead Oncorhynchus mykiss smolts face multiple survival threats during their migration from freshwater to the ocean, with predation by harbor seals being a significant factor. Increases in Puget Sound water temperature and the Northeast Pacific marine heat wave led to higher smolt survival probabilities, while ecological changes in the system also influenced smolt survival rates.

Summary: Claywater can effectively substitute for algae as a turbidity agent in the feeding of larval sablefish, reducing costs and improving growth. Both gradual and sudden transitions from greenwater to claywater had different impacts on feeding rates and body weights, but resulted in higher body weight and biomass by the end of the larval period. Transitioning at day 8 minimized algae costs, while transitioning at day 18 maximized biomass, offering potential benefits for sablefish aquaculture.
