Abstract

Fisheries and aquaculture play a pivotal role in food production, nutritional security and employment generation for millions of people. Coastal marine aquaculture is one of the emerging area for marine food fish production, and is mainly performed in the sea and in coastal ponds. Mariculture and coastal aquaculture collectively produced 30.8 million tonnes (USD 106.5 billion) of aquatic animals in 2018, and they are mainly from marine cages, coastal cages and coastal earthen ponds. Increasing marine food fish production through innovative and intensive culture methods has increased demand for marine finfish seeds either from wild collection or hatchery based production. In this context, nursery rearing plays an important role in supplying sufficient number of fingerlings at ready to stockable size in grow-out culture for better survival and faster growth. Larval rearing ends after the larvae achieve full metamorphosis. Fry harvested from larval tanks are often not strong enough for direct stocking in grow-out farms. Thus, nursery rearing of fish larvae is important for production of stockable size fish in grow-out culture system. The concept of nursery rearing system is an age old practice in finfish aquaculture. It was evident that healthy seeds are key to a good healthy grow out culture and subsequent harvest. Maintaining healthy and disease free stock is of prime importance for achieving better production in grow-out system. So, nursery rearing concept gives better opportunity to maintain large numbers of fish fingerlings in small area, which facilitate for effective management. In aquaculture, three tier farming concept is practiced and has been well advocated in commercial farming systems for both fish and shrimp aquaculture. The major steps in farming operations are initial larval rearing, mid nursery rearing and final growout phase. The mid nursery rearing is the crucial phase in farming practices, where properly managed and well nurtured individuals will perform better with high growth, better survival, and reduced culture duration in grow-out period. Nursery rearing practices are classified into two major categories; indoor and outdoor systems; where indoor based culture is performed either by flow through or recirculation based concept in FRP (Fibre Reinforced Nursery rearing of Indian pompano in different culture systems Sekar Megarajan, Shiva Ponnaganti, Narasimhulu Sadhu, Durga Suresh, R. 7 Plastic) /concrete/collapsible tanks, outdoor based system is performed either running or moving waters in hapa erected or installed in earthen ponds, coastal cages and marine cages.
