Growth modelling and forecasting of common carp and silver carp in culture ponds: A re-parametrisation approach

Abstract

The available forecasting models for growth pattern in fish are based on either classical approach or a particular growth model. In the present study, reparamerisation methodologies were attempted for forecasting growth of fish cultured in cemented ponds of plain areas. Forecasting methodology is not readily available for any other types of ponds for uplands of India. So, other appropriate growth curves (Logistic, Gompertz and von-Bertalanffy) were considered while developing the most suitable model for forecasting fish (common carp Cyprinus carpio var communis and silver carp Hypophthalmichthys molitrix) production from cemented ponds. Gompertz-1 and Logistic-1 models gave the best fit as well as fish yield forecasting, two months ahead from various ponds
