Assessment of Tilapia–Freshwater Prawn Co-Culture Schemes in Tanks and Lake-Based Cages for Increased Farm Production

Abstract: The technical viability of tilapia (I-ExCEL strain Nile or red) and giant freshwater prawn (GFP) co-culture in cages-within-tanks was evaluated while appropriate feeding protocols for tilapia-GFP co-culture in cages in a eutrophic lake were determined. Specifically, production parameters in all test species grown for five months in tank co-culture (where only tilapias were fed) were compared, while the best feeding protocol from among the following treatments: (a) Tfed—fed tilapias; (b) GFPfed—fed prawns and (… Show more

“…Its large-scale production is being established [188] and is worth more than USD 10 billion in economic benefits annually [189]. Polyculture is also referred to as co-culture [190]. There are at best three common types, including direct, pond-cum-cage, and spatially sequential polyculture (Figure 5) [48,73].…”

“…This is interesting because this topic is still debated in research, with some scholars suggesting there can be up to 40% higher fish yields through implementing polyculture and others proposing that is has no effect on fish yields [18,19]. Exploring optimal combinations of fish species beyond the ones analyzed in this study [46], considering ecological compatibility and market demand, could further enhance the income potential of aquaculture farms. Future research efforts could focus on identifying suitable species combinations and assessing their economic viability, offering valuable insights for fish farmers.…”

“…The model includes variables related to fish consumption, such as the distance to the nearest fish market [24,38,44], the frequency of fish consumption [14,22,24], the types of fish consumed (to explore whether the consumption of local fish is associated with higher levels of food security) [3,45], and the utilization of the entire fish for nutritional intake. Demographic and socio-economic variables, including age, household size, gender dynamics, education, and wealth, were also employed as control variables [22,[46][47][48]. The variables and their expected effects are summarized in Table A2 in Appendix A.…”

“…When skipping feeding versus daily feeding were assessed in cages in selected lakes in the Philippines, no statistically significant differences were noted, especially when tried on tilapia farmed in Laguna de Bay cages (Cuvin-Aralar et al, 2012). Cost-effective feeding management schemes have likewise been tried on tilapia reared together with prawns for co-culture in Laguna de Bay net cages (Romana-Eguia et al, 2021), where daily feeding favored better growth in the farmed tilapias reared either alone or in co-culture, especially during the wet season. In this present study, it appears that daily feeding using floating feeds and following a sliding scheme ration for the entire tilapia cage rearing operations were both technically and economically feasible.…”

“…Feed management-related data were analyzed with the growth parameters to determine the technical and economic feasibility of adopting the supplemental feeding protocols. In general, a feeding efficiency financial analysis can explain how fish growth and feed input costs are analyzed to identify optimal practical feeding management protocols in fish culture (Romana-Eguia et al, 2021).…”
