Impaired reproduction, energy reserves and dysbiosis: The overlooked consequences of heatwaves in a bivalve mollusc

Marine Pollution Bulletin, Journal Year: 2023, Volume and Issue: 193, P. 115192 - 115192

Extreme events like Marine Heatwaves (MHWs) are becoming more intense, severe, and frequent, threatening benthic communities, specifically bivalves. However, the consequences of non-lethal MHWs on animals still poorly understood. Here, we exposed Manila clam Ruditapes philippinarum to MHW for 30 days provided an integrative view its effects. Our result indicated that albeit non-lethal, reduced clam's energy reserves (by reducing their hepato-somatic index), triggered antioxidant defenses (particularly in males), impaired reproduction (via production smaller oocytes females), dysbiosis digestive gland microbiota altered animals' behaviour impacting burying capacity) filtration rate. Such effects were seen also at RNA-seq (i.e. many down-regulated genes belonged reproduction) metabolome level. Interestingly, negative pronounced males than females. results show influence animal physiology multiple levels, likely fitness ecosystem services.

Resilience and Social Adaptation to Climate Change Impacts in Small-Scale Fisheries

Frontiers in Marine Science, Journal Year: 2022, Volume and Issue: 9

Published: May 4, 2022

Small-cale fisheries are important for livelihoods, food security, jobs and income worldwide. However, they face major challenges, including the increasing effects of climate change that pose serious risks to coastal ecosystems fishing communities. Although scientific research on impacts has increased in recent years, few studies have explored social small-scale fisheries. Using Galicia (Spain) as a case study, we investigated individual household-level adaptive responses among fishers three guilds (Cambados, Campelo, Redondela). Specifically, estimated economic vulnerability shellfishers assessed diversity used deal with change. fishers’ strongly depends shellfishing all studied areas, our findings show less experience lower engagement fisher associations tend increase fishers.

The Impact of Climate Change on Bivalve Farming: Combined Effect of Temperature and Salinity on Survival and Feeding Behavior of Clams Ruditapes decussatus

Frontiers in Marine Science, Journal Year: 2022, Volume and Issue: 9

Published: July 22, 2022

European clam ( Ruditapes decussatus ) is one of the most relevant emergent bivalve species from aquaculture sector in Europe with high economic value. Climate changes represent a potential limiting factor to this activity, directly interfering survival and behavior bivalves. Severe fluctuations temperature along periods heavy rainfall or drought that significantly change salinity can promote physiological stress bivalves, resulting behavioral responses and, extreme cases, leading mortalities. This study aimed evaluate combined effect on mortality feeding R. . Juveniles adults were exposed ranges (5°C–35°C) (0–40). Mortality registered every 24 h each 120-h trial. A control range was set between 15°C 23°C, where considered as normal scenario. Our data suggested 15 “turning point,” point which occurred distinct patterns behavior. The results evidently indicate abrupt reductions sharp increases will lead decussatus. revealed be more sensitive increase less saline environment, suffer greater faster mortalities, resistant extremely temperatures under conditions. sporadic are predicted occur south due climate contribute compromise recruitment clam, thus threatening production consequently impacting sector.
