Feed is one of the mjor inputs in quculture system nd constitutes 60%–80% of totl production costs of tilpi. Inpproprite selection of feed qulity nd the feeding strtegy fects the feed utiliztion resulting in high food conversion rtio (FCR). A 60 dys experiment ws conducted to evlute the growth performnce nd immuno•physiologicl responses of GIFT tilpi, (Oreo• chromis niloticus) by pulsed feeding under biofoc culture system in inlnd sline wter. For the experiment, feeding pttern in pulsed ws followed viz., in situ biofoc with dily feeding (T1), in situ biofoc with lternte dy feeding (T2), insitu biofoc with every third dy feeding (T3), insitu biofoc with no feeding (T4), nd cler wter control with dily feeding (C) ech in triplictes. Biofoc bsed tretment receiving dily feeding (T1) resulted in signifcntly (P < 0.05) higher verge body weight, weight gin, nd specifc growth rte (SGR) compred to control. T1 nd C showed  signifcntly similr feed conversion rtio (FCR) nd protein efciency rtio (PER). Fish mintined in T4 grew the lest nd survivl ws lowest (85%). Te immunologicl prmeters showed  signifcnt diference (P < 0.05) for nitroblue tetrzolium (NBT) nd myeloperoxidse content wheres no signifcnt diference (P > 0.05) for lysozyme ctivity ws observed. Higher NBTctivity ws observed in biofoc bsed tretments compred to control. Activity of superoxide dismutse (SOD), ctlse (CAT), nd glutthione peroxidse (GPx) ctivity were considerbly higher (P < 0.05) in biofoc bsed tretments thn control. Among biofoc bsed tretments the ntioxidnt ctivities were lower in T1. Te crbohydrte metbolism enzymes lctte dehydrogense (LDH) nd mlte dehydrogense (MDH) were lower in T1,T2, nd T3 compred to control nd T4. In conclusion, in•situ biofoc with dily feeding is found to be efective in growth im• provement nd to elicit immune•physiologicl responses in GIFT tilpi under pulsed feeding using biofoc bsed system. 1.Introduction In Indi, round 8.621 million h of lnd hs been bdly fected with the problem of soil slinity nd 1.93 million km 2 res is under lden with ground sline wter [1]. Agriculturl frmers bndon these lnds s brren felds due to poor griculture productivity [2], but these lnds prove to be  vluble sset for quculture [3]. Aquculture cn be the right strtegy to reduce the slt content in un• derground wter tbles nd to generte income through enhnced production of euryhline nd mrine fshes with high growth potentil [3, 4]. However, its expnsion is limited due to scrcity of wter sources nd competition with other wter users such s griculture nd urbn c• tivities [5]. Also, intensifction in this sector in ecologiclly sensitive res nd frgile lnds led to environmentl degrdtion, if efuents re not treted before dischrge [6]. So lternte nd sustinble use of vilble wter resources hs become  necessity for production of food especilly qulity protein to feed the growing popultion [7]. Biofoc technology (BFT) would be  remunertive nd sustinble mens to reclim slt•fected resources for food Hindawi Aquaculture Research Volume 2023, Article ID 6079177, 11 pages https://doi.org/10.1155/2023/6079177
