In long walk to water why do the fishermen not share their food?

In "A Long Walk to Water," the fishermen do not share their food with Salva and the other travelers because they are focused on their own survival amidst the harsh conditions of the Sudanese civil war. The scarcity of resources leads them to prioritize their needs over the plight of others, reflecting the desperation and self-preservation instincts that arise in times of crisis. Their refusal to share highlights the broader themes of hardship and the struggle for survival faced by many during this period.
