“…This focus often includes species, production systems and markets that may be neglected when all sector development is left to the private sector. (iii) Supporting land, water and sea tenure arrangements that enable a range of producers to engage in the sector, including the landless poor who may be able to access waterways (e.g., Adivasi Bangladesh; Pant et al, 2014), communities or cooperatives that can organize to meet local demand (e.g., Cambodia, Lao; Phomsouvanh et al, 2015) and contract-farming arrangements (e.g., India; Umesh et al, 2010) that can compete with private firms in terms of scale of production and access to input and output markets.…”

Does Aquaculture Support the Needs of Nutritionally Vulnerable Nations?

Aquaculture now supplies half of the fish consumed directly by humans. We evaluate whether aquaculture, given current patterns of production and distribution, supports the needs of poor and food-insecure populations throughout the world. We begin by identifying 41 seafood-reliant nutritionally vulnerable nations (NVNs), and ask whether aquaculture meets human nutritional demand directly via domestic production or trade, or indirectly via purchase of nutritionally rich dietary substitutes. We find that a limited number of NVNs have domestically farmed seafood, and of those, only specific aquaculture approaches (e.g., freshwater) in some locations have the potential to benefit nutritionally vulnerable populations. While assessment of aquaculture's direct contribution via trade is constrained by data limitations, we find that it is unlikely to contribute substantially to human nutrition in vulnerable groups, as most exported aquaculture consists of high-value species for international markets. We also determine that subpopulations who benefit from aquaculture profits are likely not the same subpopulations who are nutritionally vulnerable, and more research is needed to understand the impacts of aquaculture income gains. Finally, we discuss the relationship of aquaculture to existing trends in capture fisheries in NVNs, and suggest strategies to create lasting solutions to nutritional security, without exacerbating existing challenges in access to food and land resources.

“…The importance of inland fish production to closing the gap between food fish needs and supply in the coming years and to overall global food security has been emphasised in the recent past (Beard et al, ; Běně et al, ; De Silva, ). Culture‐based fisheries (CBFs), an extensive form of aquaculture that involves a stock and recapture strategy (De Silva, ), are practiced widely in lakes and reservoirs in Asian countries (Chandrasoma, Pushpalatha, & Fernando, ; De Silva, ; Phomsouvanh, Saphakdy, & De Silva, ). CBFs also contribute significantly to inland fish production in China (Wang, Cheng, et al, ).…”

The culture‐based fishery of Liangzi Lake, Yangtze River Basin, established in 1992, yielded 2,652 t/year (±167) between 2005 and 2015, dominated by stocked carps [Hypophthalmichthys molitrix (Val.) and Hypophthalmichthys nobilis (Richardson)] and mitten crab Eriocheir sinensis (Milne Edwards), accounting for 53% and 23% of the production and 20% and 52% in value, respectively. The lake had a macrophyte cover dominated by Vallisneria natans (Lour.) Hara with a cumulative biomass of 10,647 g/m2 that disappeared after a major flood in 2010 and changed its ecology. Management changes in stocking strategies introduced in the post‐flood period enabled the culture‐based fishery to maintain viability and sustainability to combat the major ecological change in the lake. The stocked species contributed significantly to nutrient removal of 24.71 ± 5.12 t/yr and 6.29 ± 0.87 t/yr of total nitrogen and total phosphorus, respectively.

“…Lao PDR has also embarked on CBF development in small water bodies in rural areas (Saphakdy et al., 2009). In Lao PDR, these water bodies are managed under different management regimes decided upon by each community, where the overall gross CBF production levels ranged from 1,350–2,844, 650–4,662 and 2,750–8,759 kg per cycle under the three management regimes adopted (Phomsouvanh, Saphakdy, & De Silva, 2015).

Culture‐based fisheries (CBF) are increasingly accepted as strategies for enhancing inland fisheries, especially in tropical Asia. In Sri Lanka, CBF development in irrigation reservoirs has gained momentum due to concerted efforts of government fisheries authorities for inland fisheries enhancement. In the present study, production trends of five irrigation reservoirs of Sri Lanka before and after the introduction of CBF were investigated and apparently optimal CBF yields were not realised. Hence, the stochastic frontier production function (SFPF) was employed to quantify technical efficiencies (TE) of CBF. For each reservoir, annual averages of input data from 2005 to 2018 (14 years) were used in the TE analysis. Hence, total sample size for estimation of SFPF was 70. Although CBF production gradually increased in all five reservoirs from 2005 to 2018, there were substantial variations of total fish production across the reservoirs. The SFPF indicated that CBF production could be further increased through more efficient management of inputs (i.e. number of fishers, mean number of fishing days per year and stocking density).
