What is it about?
Among the leading shrimp diseases that is causing the decrease of shrimp production in the country is the White Spot Disease. Rapid diagnosis and early detection of the virus is one of the most effective strategies to contain the infection (Seibert & Pinto, 2012). However, rapid diagnosis of the disease is not always readily available since a scientist is needed in conducting the diagnostic test using DNA testing. In response to this problem, this study designed a shrimp disease detection tool that can expertly identify the presence of the virus and prevent imprecision in the analysis due to human expertise inadequacies.

Why is it important?
Shrimp farming in the Philippines uses a variety of systems which are affected by the climate, availability of capital, site location, and sources of water supply, the marketing of harvested products and the availability and cost of farm inputs (Corre, 1995). However, shrimp aquaculture industry in the country experience bacterial and viral diseases that leads to major problems among shrimp farmers. Early detection and prevention of spread of WSSV in Penaeid shrimps can be achieved using the capabilities of this study. The researchers believe that this study will have a contribution in the field of aquaculture, as well as to the following: Southeast Asian Fisheries Development Center (SEAFDEC) – This study will contribute to SEAFDEC because the organization focuses on researches related to aquatic resources including the shrimp and shrimp pathogens as well as the improvements in the method of detecting the WSSV. Bureau of Fisheries and Aquatic Resources (BFAR) – rapid detection of the virus can be beneficial for BFAR as it will prevent the spread of the virus, resulting to an improved fisheries productivity. Shrimp Experts/Shrimp Disease Experts – rapid detection of the disease will benefit the shrimp expert and shrimp disease experts because they can easily gather samples of shrimps with diseases for their studies and experiments. Shrimp Farmers/Shrimp Farm Owners – this study will benefit the shrimp farmers and Shrimp Farm Owners of the Philippines because early prevention of the spread of the virus can increase the production of Penaeid shrimps and prevent losses in shrimp productions. Future Researchers – this study is of significance to future researchers who intend to study about the white spot syndrome virus among the shrimps
Perspectives
Early detection of white spot disease on shrimps is a great help in the aquaculture most especially for the shrimp farmers, owners and experts. This study aimed to develop a WSSV detection tool and determine the accuracy and reliability rate of the performance of the system. After conducting careful experimentations and analysis, the researchers were able to formulate the following conclusions: 1. The color of the spots and the location of the white spots are the significant parameters used for the detection of WSSV among shrimps. 2. The size of the spots is insignificant in this study and cannot be measured accurately for the reason that it is fully dependent on the angle and the distance of the camera from the shrimp when the picture was taken. 3. Lighting in the image of the shrimps affects the diagnosis of the system for the reason that the system detects the reflected light on the carapace as white spots. Having obtained the accuracy and reliability rate of the system, the researchers can therefore conclude that the Hybrid ANN and Fuzzy Logic algorithm is an effective and helpful method for the detection of white spot disease among shrimps and other diagnostic problems.
