Abstract

Inadequate protein intake results in stunting and wasting in children as well as cause health problems at all ages. Proteins from fish excel in promoting children's growth and family health. Consuming catfish has the potential to improve family nutrition because of its affordability, ease of being raised, and dense contents of proteins and beneficial fats. This study aimed to compare the growth of catfish raised in concrete ponds and buckets and also to compare catfish fed with probiotic-fortified and regular feeds. The concrete pond was stocked with 300 juveniles, whereas 80 juveniles each were placed in two buckets. The experiment lasted for 12 weeks. Probiotic feed was given twice a day. After six weeks, probiotic feed in one of the buckets was replaced with regular feed. Body length and weight were assessed once per week with 10-20 % samples of the population. Data were analyzed statistically with two-way ANOVA and post hoc Duncan (α=0.05). Catfish raised in buckets can grow similarly to ones reared in concrete ponds with a suitable ratio of fish to water volume and proper care. Probiotic feed increased catfish growth rate. However, there was no significant difference after replacing probiotic feed with regular feed.
