| 内容記述 | Oyster farming is one of the oldest forms of aquaculture and one of the largest markets in the world. Oysters are sessile organisms whose shell morphologies are highly variable, and strongly adhere on host substrates. The relationship between shell morphology and soft body mass in oysters is poorly understood because of the difficulty in the morphological analysis of complex-shaped shells. The “ideal” shell shape for aquaculture production has not been determined for more than 2,000 years. In this study, we tried to develop a new analytical approach to estimate the soft body mass from the shell morphology in Pacific oyster, Crassostrea gigas. We assumed that the whole shell morphology should be translated into numerical values that characterize the soft body mass, rather than traditional indices comprised of a limited number of linear distances such as shell length and width. We first collected the overhead photographic data from the shells. These data were transformed into numerical values that represent the morphological components using elliptic Fourier analysis. Then, we screened the morphological components that could affect the relative soft-body mass using a generalized linear model. Using these analytical results, we developed a numerical model suitable for evaluation of the oyster meat production by the shell morphology. Our results will help establish a new criterion for assessing the quality of oysters as seafood and promote oyster farming. | |||||||||||||||||||||||||
