“…The intensity of the effect of this parasite is variable, being milder in France, despite the high prevalence (up to 100%) (Dang et al, 2010) and in Spain. Strong effect is observed in Portugal (Ruano et al, 2015), South Korea (Choi and Park, 2010) where mortalities were associated with stress of high seawater temperature (Nam et al, 2018), and Japan where high prevalence (100%) and intensity were associated with declining R. philippinarum populations (Waki et al, 2018).…”

Bivalves were long thought to be "symptomless carriers" of marine microalgal toxins to human seafood consumers. In the past three decades, science has come to recognize that harmful algae and their toxins can be harmful to grazers, including bivalves. Indeed, studies have shown conclusively that some microalgal toxins function as active grazing deterrents. When responding to marine Harmful Algal Bloom (HAB) events, bivalves can reject toxic cells to minimize toxin and bioactive extracellular compound (BEC) exposure, or ingest and digest cells, incorporating nutritional components and toxins. Several studies have reported modulation of bivalve hemocyte variables in response to HAB exposure. Hemocytes are specialized cells involved in many functions in bivalves, particularly in immunological defense mechanisms. Hemocytes protect tissues by engulfing or encapsulating living pathogens and repair tissue damage caused by injury, poisoning, and infections through inflammatory processes. The effects of HAB exposure observed on bivalve cellular immune variables have raised the question of possible effects on susceptibility to infectious disease. As science has described a previously unrecognized diversity in microalgal bioactive substances, and also found a growing list of infectious diseases in bivalves, episodic reports of interactions between harmful algae and disease in bivalves have been published. Only recently, studies directed to understand the physiological and metabolic bases of these interactions have been undertaken. This review compiles evidence from studies of harmful algal Highlights  Review of the main studies on effects of marine harmful algae on bivalve immune cells (hemocytes) and on infectious disease  Harmful algae can modulate host-pathogen interactions in bivalves on various way (increase or decrease the infection)  Some experimental studies report the involvement of cellular immunity and global physiological weakness in the modulations  Other mechanisms possibly involved: HAB effects on bivalve filtration; direct

The Manila clam, Ruditapes philippinarum, introduced in the Venice lagoons in 1983 and rapidly spread to the nearby coastal lagoons represents one of the most important commercially-exploited resources of this area. Abundance, size-class and biomass distribution of the wild population living in the Pialassa Baiona lagoon were assessed and related to the hydrological and sediment characteristics. Despite the lagoon being affected by eutrophication, chemical and thermal pollution, the clams were harvested by about thirty professional fishermen until 2003. The commercially available stock was estimated at 36.8 10 3 kg in July 2002, 29.3 10 3 kg in April 2003, and 10.3 10 3 kg in October 2003. Stock estimations and observed mortality were in good accordance with the fishermen data. The decline of the available stock could be due to both overfishing and the extraordinary summer heat wave occurred in 2003, which may have reduced larval recruitment and increased the mortality. Overall, the juvenile recruitment appeared insufficient to annually restore the natural stock. Although the national and regional high relevance of clams market, local harvesting of wild populations appeared marginal and inadequate to support a remunerative commercial activity, due to the variability and unpredictability of the annual yield and the lack of a sustainable management based on a production chain’s approach.

1The Manila clam Ruditapes philippinarum -synonym Venerupis philippinarum (Adams and Reeve, 2 1850) is now one of the top 5 most commercially valuable bivalve species worldwide. Originally 3 from the Indo-Pacific region, it has been introduced in many countries for fisheries and aquaculture, 4 including estuarine environments along Atlantic and Mediterranean European coasts. Yet despite its 5 commercial value and widespread distribution, the precise origins of stocks remain speculative and 6 the genetic diversity of introduced populations is poorly known. Thus, the aim of this work was to
