Mud crabs are a primary source of livelihood of a community in Ilog, Negros Occidental. Inside a shaded structure located in Ilog, mud crabs grow in rows of individual plastic cages, allowing a continuous safe harvesting of crabs even in times of bad weather.
The Ilog Entrepreneurs Association (IEA) first entered the mud crab fattening industry in 2024, relying only on bamboo-and-wood cages placed directly in brackish river water, yet much of the business remained in the hands of the environment. The initial project was stopped due to high risk factors affecting the crabsโ condition and the harvesting process, such as the weather and the physical weight of the cages.
โWe had a difficult time before because we were using traditional cages made of bamboo and wood. It was difficult to harvest the crabs whenever the weather changed, because the cages were heavy. Some crabs would die," IEA president Trinidad Diamante said in Hiligaynon.
Seeking a solution, the association partnered with the Central Philippines State University (CPSU)-Ilog, the university that introduced Crab Vertical Farming Technology (CVFT). This CVFT system places mud crabs in individual cages made from recycled plastic containers. These cages are then arranged inside a shaded structure, away from the full exposure of the river.
A submersible pump keeps water, along with specially formulated components, moving through the system. The water quality and temperature can be monitored more closely by the farmers, paving the way to maintain a sustainable growing environment for the crabs and allowing control over their development.
Diamante testified that it can increase the weight of mud crabs; from an initial weight of 200 grams, CVFTs can add at least another 100 grams in two weeks' time. With the IEA now using CVFTs, members were able to resume crab fattening. Results were not just observed in the crabs but also in members returning to the enterprise.
These modified cages promote green technology, an innovation that contributes not only to the people but also to advancements in society while keeping the environment in mind. The CVFT system is far more than just a cage project for the community in Ilog; it may be a vital tool to combat the struggles in times of harsh weather and maintain resilience in their entrepreneurial journey.
