“…Different studies around the world have shown that R. philippinarum has various spawning periods, depending on location. In other studies, the spawning period was June-September in British Columbia (Bourne 1982), April-August and late summer in Ile Tudy, South Brittany, France (Beninger and Lucas 1984), autumn-summer in Arcachon Bay (Robert et al 1993;Dang et al 2010), June-November in Ria de Vigo, Spain (Rodriguez-Moscoso et al 1992), summer in Vostok Bay, Russia (Ponurovsky and Yakovlev 1992), May-September in the Lagoon of Venice, Italy (Meneghetti et al 2004) and summer-autumn in Tokyo Bay, Japan (Toba et al 2007). These different spawning seasons are probably related to the seawater temperature (Dang et al 2010) and variations in seasonal seawater temperature during the spawning season, especially in the neighbourhood of intertidal zone, which may also explain the high variability in spawning patterns.…”

Ruditapes philippinarum, a venerid clam, is a dominant species in the sandy and muddy areas in the coastal waters of the Marmara Sea. Intensive commercial harvesting of this species is conducted in these regions. We studied the population dynamics of R. philippinarum on the southern coast of the Marmara Sea (Bandırma). Samples were collected on a monthly basis between September 2012 and August 2013. Seasonal von Bertalanffy growth parameters using the length-frequency distribution of R. philippinarum were estimated at L ? = 67.50 mm and K = 0.33 year -1 , and the seasonal oscillation in growth rate was 0.53. The slowest growth period was in January. The growth performance index and potential lifespan were 3.182 and 8.06 years, respectively. The growth relationship was confirmed to have a positive allometric pattern. The average total mortality rate was estimated to be 0.777 year -1 , whereas the natural and fishing mortality rates were 0.539 and 0.238 year -1 , respectively. The current exploitation rate of R. philippinarum was 0.306. The recruitment pattern peaked during June-August, and spawning occurred between May and August. The results of this study provide valuable information on the status of R. philippinarum stocks.

“…Growth rates were measured as dry tissue and dry shell mass in grams over time for six individuals per species per treatment. These same individuals were then immediately used for determination of overall condition using the following equation: condition index=(dry tissue mass/dry shell mass)×100 (Beninger and Lucas, 1984).…”

Freshwater mussels, aquatic keystone species, are in global decline. Long life spans, sedentary lifestyles, and unique reproductive strategies involving obligate parasitic stages make unionid freshwater mussels particularly sensitive to environmental perturbations resulting from global climate change. A greater understanding of the mechanisms by which closely related species differ in their response to thermal challenge is critical for successful conservation and management practices. As such, both an acute heat shock and a chronic warming simulation were conducted in order to evaluate responses between hypothesized thermally tolerant (Villosa lienosa) and thermally sensitive (Villosa nebulosa) freshwater mussels in response to predicted thermal warming. Multiple biological responses were quantified, including mortality, condition index, growth rates, glycogen and triglyceride content, and candidate gene expression. During acute heat shock, both species upregulated HSP90 and HSP70, although V. lienosa showed consistently greater transcript levels during upregulation. This pattern was consistent during the chronic warming simulation, with V. nebulosa showing greater induction of HSP60. Chronic warming stimulated increases in condition index for V. nebulosa; however, declines in growth rates during a recovery period were observed with no concurrent change in tissue glycogen levels. This contrasts with V. lienosa, where tissue glycogen significantly increased during chronic warming, although no response was observed for condition index or growth rates. These biological differences might indicate disparate thermal stress response mechanisms correlated with metabolic demands and resource utilization, and could thus be a factor influencing current ranges of these two species and their ability to cope with future persistent warming in their native habitats.

“…Therefore, this quantity is frequently used to characterize the health of an organism given the local environmental conditions (Beninger et al Lucas, 1984). The weak association between the filtration rates and either CI and body size indicated that the individuals belonging to the studied size class (>15 mm), regardless of their size, could provide similar impacts through their filtration activities.…”
