“…In contrast, Young and Williams (1984), as well as Young et al (1987), found no mortalities or growth retardation in glochidia-infected trout. Similar data were obtained from experimental infestation of Atlantic salmon parr (Treasurer et al, 2006). Such differences can be explained by the occurrence of different host fish strains or different environmental conditions (e.g., temperature), which can all affect host-parasite interaction.…”

-The decline of freshwater pearl mussel (Margaritifera margaritifera L.) populations is globally well documented, but there is a lack of knowledge concerning the status of the species and its interaction with host fishes in the rivers of the White and Baltic Seas. This study aimed to identify the host fish of pearl mussel in four rivers of Karelia (Northwest Russia), to analyse the duration of the parasitic phase, and the susceptibility of fish hosts to the infestation. Juvenile sea-migrating and land-locked Atlantic salmon (Salmo salar L.) were identified as the most important hosts. In the Keret' River, reduced numbers of juvenile Atlantic salmon are likely to result in a decline of pearl mussel. This problem does not appear to be present for the other three studied rivers. Pearl mussel glochidia were mostly found in yearlings (0+), whereas older fish were infected less, suggesting a more complex pattern of host use than commonly expected. The remote location of Karelian pearl mussel rivers, the high number of pearl mussels in them, and their rather pristine state all suggest that these rivers have a high conservation priority. The importance of Atlantic salmon as a host fish and the emerging declines of Atlantic salmon populations, e.g., in the Keret' River, suggest that the sustaining of this host species should have a high conservation priority.

Le déclin des populations de la moule perlière (Margaritifera margaritifera L.) est globalement bien documenté, mais il y a un manque de connaissances concernant le statut de l'espèce et son interaction avec les poissons hôtes dans les rivières des mers Blanche et Baltique. Cette étude visait à identifier les poissons hôtes de la moule perlière dans quatre rivières de la Carélie (Ouest de la Russie), pour analyser la durée de la phase parasitaire, et la sensibilité des poissons hôtes à l'infestation. Les juvéniles de saumon atlantique migrants ou land-locked (Salmo salar L.) ont été identifiés comme les hôtes les plus importants. Dans la rivière Keret', la réduction du nombre de saumons atlantiques juvéniles est susceptible d'entraîner une baisse de la moule perlière. Ce problème ne semble pas être présent pour les trois autres rivières étudiées. Les glochidies de moule perlière ont été principalement trouvés dans les poissons de l'année (0+), tandis que les poissons plus âgés ont été moins infectés, ce qui suggère un modèle de l'utilisation des hôtes plus complexe que généralement prévu. L'éloignement des rivières de Carélie à moules perlières, le nombre élevé de moules perlières présentes, leur état plutôt vierge suggèrent que ces rivières ont une haute priorité de conservation.

“…Perhaps the simplest way to achieve host encystment of glochidia is by making gravid mussels cohabit with juvenile salmonids in hatchery troughs (Treasurer et al 2006). Typically 0+ salmonid fry are used (either Atlantic salmon or brown trout) to maximise encystment, as older salmonid parr may show acquired immunity from previous exposures (Treasurer et al 2006).…”

“…Typically 0+ salmonid fry are used (either Atlantic salmon or brown trout) to maximise encystment, as older salmonid parr may show acquired immunity from previous exposures (Treasurer et al 2006). Rearing salmonids and mussels together appears to result in high encystment rates (Treasurer et al 2006), and it is possible that the release of glochidia in Margaritifera margaritifera is facilitated by the close proximity of suitable fish hosts, as shown in other freshwater mussels (Haag & Warren 2000). Research on the role of fish hosts in triggering M. margaritifera spatting would seem warranted in order to optimise captive breeding programmes.…”

“…This is expected to offer greater control over the survival and growth of mussels (Treasurer et al 2006, Preston et al 2007), but it represents a long-term programme that requires a committed facility and staff, as several years will pass between infecting the fish hosts and the production of juvenile mussels for restoration.…”

Captive breeding of the endangered freshwater pearl mussel Margaritifera margaritifera

Freshwater pearl mussels (Unionidae: Bivalvia) rank among the most endangered aquatic invertebrates, and this has recently prompted a number of initiatives designed to propagate the species through captive breeding. Yet there are few guidelines to aid in freshwater mussel culture for conservation, and few or no results on the fate of released juveniles. We reviewed various ex situ strategies for freshwater mussel conservation with emphasis on the freshwater pearl mussel Margaritifera margaritifera (L.), one of the most critically endangered unionids. Captive breeding could help safeguard critically endangered populations, but current rearing methods need to be optimised. Areas in particular need of research include the collection and storage of viable glochidia, the development of efficient rearing systems, and the formulation of algal diets. Likewise, the degree of host specificity warrants further investigation, as this will largely dictate the success of reintroduction programmes. Finally, we note that more information is needed on the degree of genetic structuring and post-release survival before translocation programmes can be recommended. As with other conservation projects, captive breeding of the freshwater pearl mussel cannot compensate for loss of critical habitats and is likely to be most efficient in combination with in situ conservation, not in isolation.

“…The development of culture techniques suitable for this species has been on-going for many years in countries such as Malaysia, Thailand, Australia, and Canada (Rosenlund and Skretting, 2006;Treasurer et al, 2006). Larvae and juveniles are typically produced and reared in land-based facilities where conditions can be controlled.…”

Abstract:In this study we aimed to analyze the effects of water temperature and diet on the length-weight relationship and condition of juvenile Malabar blood snapper Lutjanus malabaricus over a 30-d experimental period. The experiment was conducted in the laboratory using a flow-through-sea-water system. The fish were subjected to four different temperatures (22, 26, 30, and 34 °C) and two diets (commercial pellet and natural shrimp). Fish were fed twice daily. L. malabaricus exhibited negative allometric growth (b<3) at the beginning of the experiment (Day 0) at all temperatures and both diets except for 22 °C fed with shrimp, which showed isometric growth (b=3). Conversely, at the end of the experiment (Day 30) fish showed isometric growth (b=3) at 30 °C fed with the pellet diet, indicating that the shape of the fish did not change with increasing weight and length, and a positive allometric growth (b>3) at 30 °C fed with shrimp diet, which indicated that fish weight increases faster than their length. The rest of the temperatures represented negative allometric growth (b<3) on both diet, meaning that fish became lighter with increasing size. The condition factors in the initial and final measurements were greater than 1, indicating the state of health of the fish, except for those fed on a pellet diet at 34 °C. However, the best condition was obtained at 30 °C on both diets. Nevertheless, diets did not have a significant effect on growth and condition of juvenile L. malabaricus. The data obtained from this study suggested culturing L. malabaricus at 30 °C and feeding on the pellet or shrimp diet, which will optimize the overall production and condition of this commercially important fish species.
