Edible marine mollusks including clams, oysters, mussels, as well as several gastropods are considered as a significant resource as seafood, therefore; they have become a vital socio-economic entity for coastal communities. Considering these facts, investigations are being carried out in many parts of the world in order to understand nutritive value of these creatures.
The biochemical constituents, the percentage edibility as well as the condition index differ seasonally among bivalves. It is reported that both exogenous and endogenous factors like food availability, water temperature and the gametogenic cycle are responsible for these variations.
Percentage edibility as well as the condition index, both are being extensively used in bivalve aquaculture practices to identify the spawning season and to evaluate the best harvesting season1. Moreover, the condition index also describes the health index and physiological processes2.
Some scientists have reported the oxygen consumption investigations regarding the psammobiid Soletellina diphos3. But to date, there is no data available about the biochemical composition, percentage edibility as well as condition index of this species.
Therefore, a new study was carried out to investigate the seasonal fluctuations of the biochemical constituents in different parts of the body of the psammobiid Soletellina diphos and the percentage edibility as well as condition index4.
This study showed that biochemical components and physical fitness fluctuate with the seasons. Therefore, scientists suggested that the harvesting of S. diphos should be done in the post-monsoon season (September-October) when the seafood is at its maximum nutritive value. Conversely, the winter (November-January) and summer (April-May) seasons are not best for such harvesting because these seasons possess low biochemical status of these clams as well as low percentage edibility and condition index.
The information regarding biochemical composition, the percentage edibility and the condition index of S. diphos is very important since they reflect on the physiological fitness, reproductive output and nutritive value of the clams. A good condition index is a symbol of the high accumulation of nutrient, particularly of proteins, glycogen as well as lipids. Conclusively, precise and sufficient information about these aspects of S. diphos will ultimately promote the development of sustainable management practices in bivalve aqua farming.
