Pacific oysters () are a valuable aquaculture product that provides important ecosystem benefits. Among other threats, climate-driven changes in ocean temperature can impact oyster metabolism, survivorship, and immune function. We investigated how elevated temperature impacts larval oysters during settlement (19-33 days post-fertilization), using shotgun proteomics with data-independent acquisition to identify proteins present in the oysters after 2 weeks of exposure to 23 °C or 29 °C.

- Tanner crab is important for the economy but is facing threats from ocean warming and a disease caused by the dinoflagellate Hematodinium, leading to concerns about its survival.
- Researchers created RNA-seq libraries from crab samples with different infection statuses and temperatures to study gene expression, revealing that temperature affects genes related to lipid storage, oxidative stress, and morphogenesis.
- The findings suggest that the effects of temperature on gene expression may influence the crab's energy allocation and immune response, shedding light on how the disease could impact crab physiology as ocean temperatures rise.
Geoduck clams (Panopea generosa) are an increasingly important fishery and aquaculture product along the eastern Pacific coast from Baja California, Mexico, to Alaska. These long-lived clams are highly fecund, although sustainable hatchery production of genetically diverse larvae is hindered by the lack of sexual dimorphism, resulting in asynchronous spawning of broodstock, unequal sex ratios, and low numbers of breeders. The development of assays of gonad physiology could indicate sex and maturation stage as well as be used to assess the status of natural populations.
