“…In the following October, mussels might enter into a new reproduction period again, but no intense as compared to Spring months, which could be named second reproduction season of the same year (Figure 3). Parallel observations are reported in the literature that the maximum meat yield of mussels (Parreysia corrugata) was determined in the reproductive stage (Ramesha and Thippeswamy 2009). The high meat yield and condition index corresponds with gonadal development of Lamellidens corrianus in Vasind, India (Babar et al 2017).…”

The effects of environmental factors and reproductive activities on proximate composition of freshwater mussels, Unio pictorum, was investigated from February 2013 to February 2014 in Sinop, Turkey. Environmental parameters including total particulate matter, inorganic matter and organic matter, chlorophyll-a and temperature were determined monthly during the experimental period. Mean protein, lipid, moisture and meat yield were 56.03±0.79%, 4.42±0.31%, 82.19±0.21% and 21.75±0.91%, respectively. The obtained data indicate that the proximate composition of mussels is highly correlated with environmental factors and reproduction cycle. In conclusion, freshwater mussel based protein should be evaluated an alternative source of protein for the feed industry.

“…The positive allometric pattern (b > 3) considering the total length and total weight of A. edentula conforms to the findings in the study of Degamon and Gamalinda Turra et al, (2018), Elvira and Jumawan (2017), Ramesha and Sophia (2015), Miley et al, (2012) and on the study of Park and Oh (2002). According to Perez and Santelli (2018), this growth pattern is typical to infaunal burrowing bivalves.…”

Bivalves and gastropods are among the most important food resource in coastal communities. The destructive ways of harvesting these mangrove associate fauna may cause a threat to the forest and may alter the physiological condition of these organisms. The length-weight relationship of two bivalves (Anodontia edentula and Saccostrea cuccullata) and 11 gastropods (Littoraria angulifera, Littoraria melanostoma, Littoraria scabra, Chicoreus capunicus, Tenguella musiva, Nerita exuvia, Nerita lineata, Cerithidea decollate, Terebralia palustris, and Terebralia sulcata) species collected from the mangrove forest of Barangay Nabago, Surigao City was assessed in this study. A. edentula exhibits positive allometry (b=3.7002) while S. cuccullata shows negative allometry (b=2.6145). The 11 gastropod species demonstrate a negative allometric pattern (b<3). The negative allometric pattern of these species indicates that the length increased faster than the weight, which could be attributed to the different environmental factors in the area. The data obtained in this study is essential for the monitoring of these organisms and management of the entire mangrove ecosystem in the area.

“…Several studies observed variations in the shell thickness, shell shape, shell sculpture, growth rate, and overall development of freshwater mussels between the same species across different lake-stream habitats, such as A. anatina and U. tumidus in Lake Polvijärvi (the current study) have different shell morphology in comparison to the same species at Lake Viinijärvi (Abdelsaleheen, 2023), and National Nature Reserve, Wicken Lode, United Kingdom (Aldridge, 1999); or between different species at the same habitat, as Pyganodon grandis and Lampsilis radiata siliquoidea in USA ( Keogh et al, 2023); Anodonta cygnea, Pseudanodonta complanate, Anodonta anatina, Unio pictorum and Unio tumidus in National Nature Reserve, Wicken Lode, U. K. (Aldridge, 1999). Likewise, the b value (0.72) of the width-height relationship was higher for A. anatina, the present study, compared to previously studied mussel species, such as A. anatina, P. complanate, U. tumidus, P. corrugate, and P. favidens, and lower than A. cygnea and U. pictorum (Aldridge 1999;Ramesha & Thippeswamy, 2009;Thippeswamy et al, 2014). Similarly, U. tumidus in the present study exhibited a higher b value (0.65) compared to P. complanate, P. corrugate, and P. favidens, and lower than A. anatina, A. cygnea, U. pictorum, and U. tumidus (Aldridge, 1999;Ramesha & Thippeswamy, 2009;Thippeswamy et al, 2014).…”

Freshwater mussels play an important role in aquatic ecosystems and have been the subject of numerous ecological and taxonomical studies. The present study investigated the shell morphology of A. anatina and U. tumidus with focusing on the width-length, height-length, and width-height relationships in Lake Polvijärvi, Finland. Both species revealed distinct external shell morphologies, where A. anatina exhibited an elongated shell shape with a slightly curved dorsal margin and a smooth surface, while U. tumidus had a shorter and flat shell with a more swollen umbo region and a rough surface. The correlation analysis demonstrated strong positive relationships between width-length, height-length, and width-height variables for both species (R 2 ≥ 0.82). Linear regression models accurately described these relationships indicating that shell width and height increased consistently as shell length increased. Both of A. anatina and U. tumidus exhibited positive slopes in the width-length relationship suggesting a widening of shells with increasing length, however, A. anatina had a higher intercept than U. tumidus indicating a wider shell at a given length in comparison to U. tumidus. In the height-length relationship, both species showed positive relationships, but U. tumidus exhibited a steeper slope indicating a faster rate of increasing shell height with increasing length compared to A. anatina. These findings contribute to understand the patterns of shell morphology for both species; and the observed species-specific dependence have implications for their growth, proportions, ecological adaptations, and shedding light on their ecological niches and evolutionary dynamics.
