The present invention relates to the technical field of farming aquatic animals, such as bivalve mollusks, for example, oysters or scallops. In particular, the present invention provides a device, system and method for farming mollusks. This invention improves production efficiency in the farming of mollusks, mainly bivalve mollusks, by handling the movement of said mollusks and defining a specific area for each individual. This entails an improvement in individual survival, improving farming density and reducing loss caused by death.

This invention relates to the field of food nutritional quality assessment technology, and discloses a method for predicting the lipid nutritional quality of bivalve mollusks based on climate change driving factors. The method includes: determining the family to which the bivalve mollusks to be predicted belong and their geographical region; obtaining the change values ​​of climate change driving factors in the region, including temperature, aragonite saturation, salinity, and dissolved oxygen; determining the lipid nutritional quality indicators to be assessed, and constructing a prediction model based on the correlation between the lipid nutritional quality indicators corresponding to different geographical regions and different bivalve mollusks and the change values ​​of climate change driving factors; substituting the obtained change values ​​of climate change driving factors into the prediction model to calculate the predicted values; and assessing the lipid nutritional quality indicators of the bivalve mollusks to be predicted based on the predicted values ​​and outputting the results. This invention reveals the response mechanism of mollusks' lipid metabolism to climate factors, providing objective data support for the site selection assessment and suitable species screening for bivalve mollusks.

The invention provides a bivalve shell opening and closing behavior identification method. A to-be-recognized image is acquired, the to-be-recognized image is input into a trained bivalve shell detector, and whether at least one target bivalve shell exists in the to-be-recognized image or not is detected according to the bivalve shell detector. And if not, returning to execute acquisition of the to-be-identified image, and if yes, acquiring a target bivalve mollusk set. And inputting a to-be-recognized image into the trained open bivalve mollusk instance divider, detecting the to-be-recognized image according to the open bivalve mollusk instance divider, and obtaining an initial open bivalve mollusk set. And carrying out matching processing on the target bivalve mollusk set and the initial open bivalve mollusk set, and obtaining a shell opening and closing behavior identification result of the to-be-identified image. Therefore, on the basis of the bivalve detection result, the bivalve shell opening and closing behavior recognition is realized in combination with the open bivalve shell instance segmentation result, and the accuracy of bivalve shell opening and closing behavior recognition is improved.
