VIMBA VIMBA, SCALES, FORMATION, GROWTH, BODY-SCALE RELATIONSHIP
Abstract
Body-scale relationship was analyzed for two groups of vimba juveniles: fed with nauplii (AN group), and with decapsulated cysts of brine shrimp (Artemia sp.) (AC group), at 25°C. A curvilinear body-scale relationship was developed and described with an exponential function. Fish lengths at the beginning of scale formation were 24.34mmand 23.12mminANand AC groups, respectively. Formation of scales in vimba was related to the growth conditions of fish. Body growth and scale growth were unequal (allometric), and related to stadial type of development.
