“…A study by Islam et al (2015) in the same country indicates that the integrated farming system of rice and fish increases both the farm income and the frequency of fish consumption. Alawode and Oluwatayo (2019) assess the outcome of the Fadama program in Nigeria on bridging the gap between the supply and demand of protein and find that the program has a positive impact. Results from Amankwah and Quagrainie (2019) indicate that the adoption of improved fish feed technology in Ghana increases aquaculture income and reduces poverty.…”

Polyculture of fish is a common pond-based aquaculture system practiced by small-scale producers in developing countries to improve input use efficiency, and increase productivity and profits. We conduct a cross-country comparison to examine whether the economic and productivity benefits are seen in data of 1,651 ponds from 1,307 fish farming households in three countries: Bangladesh, Egypt, and Myanmar. Among these ponds, polyculture is the prevailing system, as it is practiced in 66% of them. The surveys of these households were completed in 2019. We use propensity score matching to match the ponds based on household and pond characteristics, so that ponds are compared with other similar ponds. Results indicate that the aquaculture revenue and profit of polyculture ponds are higher than those of monoculture ponds by US$4,993 and US$6,985, respectively, per hectare per cycle. The increase is also observed in the systems of tilapia polyculture and rohu polyculture, which are the two most common systems among the sampled farmers. The increase for rohu polyculture at US$7,992 in revenue and US$9,366 in profit per hectare per cycle is higher than the increase for tilapia polyculture at US$4,649 and US$6,649, respectively. However, tilapia polyculture farmers save more harvested fish for household consumption, by 72 kg per cycle, than farmers of other systems. The higher profits for general polyculture, tilapia polyculture, and rohu polyculture are statistically significant after controlling for country-level factors and have high critical value of gamma in the Rosenbaum sensitivity analysis, indicating that these results are robust. This analysis from fish farming households complements the results from pond experiments and can help to inform decision-making in aquaculture policy and training.

“…Although the aquaculture technology of saline-alkaline waters has achieved great development, a large amount of saline-alkali water resources cannot realize economic sh farming and be fully used. 11,12 As an economically important sh that lives in freshwater and one of the main edible sh species in China, crucian belongs to the Carassius genus in Perciformes: Sciaenidae. It is characterized by fast growth rate, good resistance to stress, strong tolerance to salt and alkali, and certain saline-alkali aquaculture potential.…”

“…This could be an indication of limited economic incentives for group participation as a result of the institutional malfunctioning and inconsistent objectives of the existing fisher group structure (Adetoyinbo and Otter 2020; AUC/OECD 2019). Consequently, the sector remains relatively underdeveloped and non-commercialized and is still barely connected to profitable, high-value markets (Alawode and Oluwatayo 2019;Belhabib et al 2018;Kobayashi et al 2015).…”

It is widely recognized that participation in producer groups is advantageous for smallholders who must deal with complex production and marketing constraints and dynamic business environments. However, available data on this process are scarce in the fishery sector, while existing evidence is limited by smallholders’ potential self-selection into producer groups. This study, therefore, examined the selectivity-corrected role of fisher groups in improving shrimpers’ technological and technical efficiency. Using the latest primary data from artisan shrimpers in Nigeria, we applied propensity score matching and Greene’s selectivity stochastic production frontier model to control for selection bias from both observable and unobservable factors. Empirical results from our metafrontier approach show that technical efficiency scores for members tend to be overestimated if selectivity is not properly controlled. However, the technical efficiencies and productivities of members were significantly higher regardless of how biases were corrected, implying that participation in fisher groups is positively related to increases in shrimpers’ capture and technical efficiency. Further findings suggest that current artisanal fisher groups are “production-oriented” as they ensure that members access vital shrimping inputs at lower costs. With declining returns to scale for members, the study concludes that without public and private support for collective action in the fishery sector, membership in artisanal fisher groups may not lead to significant improvement in shrimpers’ productivity. The study discusses several recommendations on how collective action can be further encouraged and developed among artisan fishers.
