“…Yet, the consequences of multiple, interacting environmental threats for parasite transmission remain unclear: when they co-occur temporally and spatially, their combined effects may be additive, antagonistic or synergistic [ 150 , 151 ]. For example, while elevated seawater temperatures increase mortality rates of oyster larvae, this can be offset by simultaneous water acidification, which reduces the growth of pathogenic bacterial infections [ 152 ]. On coral reefs, the interaction between ocean acidification and warming contributes to coral bleaching and reduced disease resistance, leading to increased pathogenicity of existing pathogens and the emergence of new diseases [ 153 ].…”

Parasitic infections are ubiquitous in wildlife, livestock and human populations, and healthy ecosystems are often parasite rich. Yet, their negative impacts can be extreme. Understanding how both anticipated and cryptic changes in a system might affect parasite transmission at an individual, local and global level is critical for sustainable control in humans and livestock. Here we highlight and synthesize evidence regarding potential effects of ‘system changes’ (both climatic and anthropogenic) on parasite transmission from wild host–parasite systems. Such information could inform more efficient and sustainable parasite control programmes in domestic animals or humans. Many examples from diverse terrestrial and aquatic natural systems show how abiotic and biotic factors affected by system changes can interact additively, multiplicatively or antagonistically to influence parasite transmission, including through altered habitat structure, biodiversity, host demographics and evolution. Despite this, few studies of managed systems explicitly consider these higher-order interactions, or the subsequent effects of parasite evolution, which can conceal or exaggerate measured impacts of control actions. We call for a more integrated approach to investigating transmission dynamics, which recognizes these complexities and makes use of new technologies for data capture and monitoring, and to support robust predictions of altered parasite dynamics in a rapidly changing world.This article is part of the themed issue ‘Opening the black box: re-examining the ecology and evolution of parasite transmission’.

“…The presence of Vibrio species observed in bivalve populations appears to be strongly associated to environmental characteristics such as high summer water temperatures and low salinity across geographical areas (Paillard et al, 2004;Garnier et al, 2008), as well as to the physiological condition of the host (Pruzzo et al, 2005). Hence, the enhanced ubiquity of Vibrio species as etiological agents has been related to climate change and increasing ocean temperatures (Paillard et al, 2004), although a palliative effect of acidification in cases of bacterial infection has also been proposed for bivalve cultures (Prado et al, 2016). Further, physiological stress due to nutritional imbalances, inappropriate food size or other dietary features may also arise in stabled animals, thus impairing host condition and increasing the risk of developing associated pathologies (Pettersen et al, 2010;Ragg et al, 2010).…”

“…The appearance of this new structure called dissoconch represents the turning point at which individuals reach the juvenile phase and acquire all adult characteristics such as the typical "pen" shape of the Pinnidae. In our case, the mortality rates observed at this pediveliger phase were possibly associated to bacterial pathologies which are widespread in hatcheries of commercial species, as well as in regular experimental activities in the laboratory (Andersen et al, 2000;Prado et al, 2016). The infection of larval cultures may be caused by external or horizontal factors such as bacteria escaping the mechanisms of water filtration or other broodstock individuals (Fontanez and Cavanaugh, 2014).…”

The development of aquaculture activities has posed an alternative solution for the preservation of some overexploited shellfish fisheries worldwide. In the same way, endemic Mediterranean bivalves such as Pinna nobilis, highly threatened by habitat loss and coastal pollution, could found in aquaculture a solution for preserving the continuity of the species. Given the endangered status of the species, the biological and ecological processes regulating natural populations have been well studied, but there are still important knowledge gaps preventing the development of viable artificial cultures. This study describes for the first time the larval development of P. nobilis (from fertilization until pediveliger larval stages) in captivity conditions. Moreover, different rearing tanks of 5, 16 and 80 L, larvae density from 1 to 600 larvae mL −1 , light conditions, food doses, were tested in order to establish the bases for the optimal rearing of the species and provide a source of individuals for restoring field populations. Results showed that 16 L tanks with a concentration of 2 larvae mL −1 , constant temperature of 21 °C, 12/12 h photoperiod and fed with an "optimal" mixture of 25 cells per μL of Chaetoceros calcitrans + 33.3 cells per μL ofPavlova lutheri + 100 cells per μL of Isochrysis galbana" appear to be the best conditions to rear larvae of P. nobilis. Different captivity conditions such as lower or higher tank volume, larvae density, or food doses; light privation did not report better results for larval development.
