Abstract: The shrimp industry in the Philippines plays a vital role in the local and national economy through exports to markets abroad such as South Korea, Japan, the USA, and others. In this study, we aimed to describe the various cultural and operational characteristics of smallholder and commercial shrimp ( P. vannamei ) farms in the Davao region. We also evaluated the current risks and challenges faced by the shrimp farmers. A semi-structured questionnaire that focused on shrimp farmers and operators in the region was used to collect data from N = 41 farmers and operators. The results showed that respondents who were engaged in smallholder farming activities had an average yield of 10 tons/ha. The commercial farms that operate intensively had an average yield of 24 tons/ha. Most smallholder operators used electric generator machines to conduct aeration in their farms using paddlewheels and blowers. More paddlewheels and blowers were employed per pond in the commercial farms compared to smallholder farms. Generally, the income of a farm was related to their yield or the number of fries rather than social factors or their size. In terms of input costs, feeds were found to have the highest cost, followed by the fry, fuel, labor, and others (fertilizers and water treatment chemicals). Most of the farmers mentioned that their shrimp are affected by diseases such as white spot syndrome (60%), black gills (35%), and red tail (5%). They perceived that the main contamination comes from the water source (31%). The main threats mentioned were declining shrimp prices in the market, source of fry, water disposal, overstocking, and water quality. This study shows that small-holding fish farmers should be supported by the government so that they can make use of the more advanced technology employed by commercial shrimp farmers in order to increase their economic productivity and lower their environmental footprint.
