Fishery access benefits early childhood development through fish consumption and fishing income pathways
Bibliographic record
Abstract
• Fishery access benefits early childhood development through fishing income and fish consumption pathways. • Fish species shape the benefits of fish consumption. • Fishing income benefits early childhood development through its effect on child growth. Within many global communities, access to natural resources benefits nutrition through provision of both food and livelihoods. In fishing communities, fish provide a rich source of essential nutrients, and fishing represents a critical income source. While evidence for the beneficial nutrients in fish abounds, fisheries’ integrated influence on nutrition outcomes through provisioning both fish for consumption and fishing income has not been examined. To address the full value of fishery resources’ contributions to food systems, within fishing communities around Lake Victoria, Kenya, we examined the effects of fish consumption and fishing income pathways on child gross motor, personal-social, and communication development as measured through the parent-reported Ages and Stages Questionnaire: Inventory across 210 households surveyed at nine time points over two years. We used mediation analyses to determine whether fishing income operates through or independently of child growth to affect early childhood development. Consumption of only one of two predominant fish species significantly benefited all three child development outcomes. Fishing income, through its effects on child growth, also significantly increased gross motor and personal-social development. Notably, the magnitude of effects of fishing income are comparable to those of fish consumption (ranging from 0.10 [90% CI 0.03–0.18] to 0.18 [90% CI 0.09–0.28]). Natural resources play a complex role in provisioning wild food, affecting nutrition outcomes through both diets and income. Disentangling these pathways and appreciating their relative magnitude are critical to advancing programs and policies to improve nutrition, early childhood development, and nature conservation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
