Abstract

Development of appropriate feeding management strategies are necessary for the optimization of feed efficiency by reducing feed wastage, deterioration of water quality and thereby ensure profitability. Different fish feeding regimes are being practiced to develop feeding protocols that are economically sustainable and cause less environmental damage by minimizing fish feed and total operational costs. Restricted feeding without growth suppression is advantageous for economic and environmental reason; result in better final product quality (Reigh et al., 2006). Moreover, such feeding schedule could improve management of personnel time and water quality, with reducing feed and labour costs. A feeding strategy resulted in compensatory growth can be one of the most effective fish culture methods to overcome unfavourable environmental condition, by improving feeding activity and accelerating growth rate of fish, by reducing feed and labour costs (Cho et al., 2006). The growth parameters especially low FCR can be obtained by adopting suitable feeding strategies. The amount of daily feed ration, frequency and timing of the feeding and presentation of predetermined ration are the major factors of feed management strategies which affects growth and feed conversion (De Silva and Anderson, 1995). Indian pompano (Trachinotus mookalee) belonging to family Carangidae is a new candidate species for mariculture in India. This fish holds immense potential for the marine finfish aquaculture sector due to its fast growth rate, easy adaptability to culture environment, fast growth rate, quick acceptance to artificial feed, pleasant appearance, good meat quality and high consumer preference and high market demand. Breeding technology for the species was developed by Visakhapatnam Regional Centre of ICAR-CMFRI in 2016 and since then seeds were consistently produced with good survival (Ritesh et al., 2018). Indian pompano has been identified as potential candidate species with its excellent growth characters, reproductive potential and nutritional qualities (Sekar et al., 2021). Starvation study on Indian pompano juveniles resulted with compensatory growth and significant growth performance (Xavier et al., 2023). The present study aimed to investigate the effect of restricted and full-feeding regimes on growth performance, feed utilization and body composition of Indian pompano (Trachinotus mookalee) fingerlings.
