1. Prevalence and Intensity of Ectoparasitic Infections in Osphronemus goramy from the Agusan River Basin  in Barangay San Teodoro  

2. Introduction

3. Giant gourami is one of the most in demand freshwater fish species for consumption because it has a delicious taste and a high nutritional content, such as fat 2.20-2.79%, protein 10.67-18.71%, carbohydrate 8.05% and fiber 3.3% ( Azrita , 2020). Giant gourami ( Osphronemus goramy ) is a vital species for aquaculture in Southeast Asia, prized for its rapid growth, hardiness, and high market demand (FAO, 2023). However, they are still susceptible to parasitic disease with a potential for the zoonotic transmission of these parasites to humans ( Eissa , 2020).

4. This study aims to provide a crucial baseline data on the prevalence and intensity of ectoparasitic infections affecting Osphronemus goramy in the Agusan River Basin, a key freshwater ecosystem in the Philippines.

5. Objectives To determine the prevalence of ectoparasite infections in Osphronemus goramy populations inhabiting the Agusan River Basin in barangay San Teodoro . To assess the intensity of ectoparasite infections in Osphronemus goramy populations inhabiting the Agusan River Basin in barangay San Teodoro . To identify the species of ectoparasites infesting Osphronemus goramy in the Agusan River Basin in barangay San Teodoro .

6. Materials and Methods A total of 30 Osphronemus goramy specimens were obtained using purposive random sampling. Fish were captured alive using cage traps. The specimens were immediately transferred to the laboratory in aerated plastic containers. Samples were classified within the three groups based on their body weight, 300g and below are small, 300-400g are medium, and above 400g are large.

8. Conclusion The prevalence and intensity of ectoparasitic infections in Osphronemus goramy from the Agusan River Basin in barangay San Teodoro is 46.7% and 1.21, indicating a general level of infection and a very low intensity respectively. Only one ectoparasite species, Lernaea cyprinacea , was identified and was exclusively located on the fins of the infected fish. These findings suggest that while ectoparasite exposure is common in the population, the health burden per individual fish remains minimal.

9. Recommendation It is recommended to conduct future research involving a larger number of specimens collected across different seasons and multiple sites within the Agusan River Basin to capture the full spectrum of ectoparasitic diversity and seasonal dynamics.
