“…Roe & Hoeh, 2003;Campbell et al, 2005;Graf & Cummings, 2007). From the middle of the 2000s, the efforts to refine captive propagation methods for mussels resulted in the near perfection of these techniques and the feasibility of their use on a large scale (e.g., Henley et al, 2001;Barnhart, 2006;Gum et al, 2011). At the present, the exponential growth on freshwater bivalves' research, both in the field of basic biology, ecology and physiology but also on applied conservation such as habitats rehabilitation and propagation, needs to be integrated and available to all ecologists, conservation biologists and freshwater malacologists.…”

Freshwater bivalves have been highly threatened by human activities, and recently their global decline has been causing conservational and social concern. In this paper, we review the most important research events in freshwater bivalve biology calling attention to the main scientific achievements. A great bias exists in the research effort, with much more information available for bivalve species belonging to the Unionida in comparison to other groups. The same is true for the origin of these studies, since the publishing pattern does not always correspond to the hotspots of biodiversity but is concentrated in the northern hemisphere mainly in North America, Europe and Russia, with regions such as Africa and Southeast Asia being quite understudied. We also summarize information about past, present and future perspectives concerning the most important research topics that include taxonomy, systematics, anatomy, physiology, ecology and conservation of freshwater bivalves. Finally, we introduce the articles published in this Hydrobiologia special issue related with the International Meeting on Biology and Conservation of Freshwater Bivalves held in 2012 in Bragança, Portugal.

“…In summary, algal species have been incorporated, in several works, into the design of direct or recirculating systems of juvenile cultures as the primary food source, due to their apparent significance in the diet of unionoids (Hudson and Isom, 1984;Gatenby et al, 1996Gatenby et al, , 1997O'Beirn et al, 1998;Tankersley and Butz, 2000;Henley et al, 2001;Kovitvadhi et al, 2008).…”

The knowledge on diet composition of the freshwater mussel Diplodon enno (Ortmann) would aid in its culture and propagation allowing, this way, the replacement of natural endangered populations in Brazil. Microalgae are the main food source for captive mussels and unionids have displayed an ability to sort algae based on the cellular characteristics prior to ingestion. The main objective of the present work is to analyze the phytoplankton composition of the water from and of the gastrointestinal contents of the mussel D. enno, as an initial step for development of a suitable rearing diet. Therefore, water samples and bivalve specimens were collected from S. Francisco River, city of Paulo Afonso, Bahia, Brazil. The microalgal composition found in water and stomach/gut content samples was very diverse being represented by the following divisions: Cyanophyta, Chlorophyta, Dinophyta and Heterokontophyta (Diatoms). Concerning the relative abundance of microalgae divisions, it is possible to state, for the water and gastrointestinal contents, that Cyanophyta represents 15% and 14%, Chlorophyta 54% in both, Heterokontophyta 31% and 27% and Dinophyta 0% and 5%, respectively. According to the Brazilian CETESB criteria for phytoplankton species classification, 50% of Cyanophyta and 15% of Chlorophyta species observed in the water samples were classified as "very frequent", as were 68% of Heterokontophyta and 33% of Chlorophyta species in the gut/stomach tract samples. Focusing at a species level, although in the water only Coelastrum sp. and Chroococcus sp. were observed in 100% and 75% of the samples, respectively, in the gastrointestinal tract the species Staurastrum sp., Aulacoseira sp., Scenedesmus sp. and Fragilaria crotonensis occurred in 80% to 100% of the samples. The present results showed that D. enno feeds not only on small chlorophytes microalgae, due to their convenient size that facilitates higher feeding rates, but also on large size diatoms, due to a possible nutritional advantage for the bivalves. Thus, a diet composed by large diatoms and small chlorophytes microalgae may be considered as the most reasonable for the maintenance of D. enno populations.Keywords: phytoplankton, gastrointestinal tract, Diplodon enno, São Francisco River.

“…Indian freshwater mussel is traditional food for the rural human population in the Indian subcontinent and it is an ingredient of artificial feed for fish and poultry (Chakraborty et al 2008). In North America the techniques of conservation aquaculture for freshwater fish species have been effectively transferred in bivalve conservation strategies (Neves 1999b;Henley et al 2001;Bogan 2008;Bogan and Roe 2008). North American native bivalves are in decline and seriously threatened by the presence of non-native invasive species, Asian clam (Corbicula fluminea) and zebra mussel (Williams et al 1993;Lydeard et al 2004;Parker et al 1998;Karatayev et al 2007;Neves 2004;Lydeard et al 2004).…”

Freshwater bivalves farming is principally focused on freshwater pearl production in Asia and conservation aquaculture in USA while in Europe is almost completely unknown. High larval mortality is considered the bottleneck in freshwater bivalve larval rearing and methods currently used in marine bivalve larval rearing can be transferred in freshwater mussels. It is likely that probiotics and aquatic microbiology will play a key role also in freshwater bivalves larval rearing. Alternative applications of freshwater mussel rearing should be studied in deep in the future as integrated productions, bioindication projects and utilization of freshwater mussel meal as potential source for fish feeds. The aim of this review is to give a description of potential applications for freshwater bivalve rearing and possible future perspectives.
