Adopting Indigenous Method and Teaching People to Fish


— DRC SSC Project Export Group Supports Local Fisheries Development

Recently, the China-Democratic Republic of the Congo (DRC) South-South Cooperation (SSC) Project Expert Group combing local realities, overcoming difficulties, and adopting indigenous method to trial-produce fish pellet feed machine and constructed net fish cage successfully. The birth of these two kinds of production machine has filled the gap of Lubumbashi and made positive efforts to promote the development of local fisheries.

With the increasing market demand of aquatic product, there are about 40 small and medium-sized fishing grounds newly built in Lubumbashi, with the number and scale rising. Since there are no feed processing plants in the region, the feed needed is imported from neighboring Zambia, making it the major cost of fisheries production. In addition, the fishing pounds are constructed by digging the ground with long construction cycle and high cost while the abundant river and lake resources in this area are not utilized. Guided by the problem, the export group organized forces efficiently to take actions to solve problems in local fishery production.

1. Trial-produce Fish Pellet Feed Machine

Against the heat and ignoring mosquito bites, Expert Zou Deliang led a group to carry out trial production of fish feed machine in the farmer machinery workshop located in Huayou Demonstration Park. They removed the cylinder from an abandoned engine and used it as a pressure vessel for storing raw feed materials through processing the bottom of the cylinder into honeycomb templates with different apertures to press the feed materials within the cylinder by jack. This raw feed material is extruded into granular product through the template and dried into pellet feed. Although the processing technology seems simple, only template specifications, feed ingredients and viscosity and pressure to match each other, qualified pellet feed could be produced. Under this condition, Zou Deliang together with the group tested the formwork specifications, feed formulation, viscosity and pressure again and again and constantly explored and improved the essentials to make the quality of the pellet feed better and better.

After a prototype of the feed machine was launched, trial production was carried out by the expert group. Overall, this feed machine adopted with indigenous method has the features of non-electricity, easy operation and maintenance, sturdy and durable with low cost (about $180 per unit, the main cost is jacks). An ordinary worker can produce more than 150kgs of pellet feed per day after training.

During the trial production, Mr. Marcel, Director of FAO’s Office in Lubumbashi and partners of the DRC side organized around farmers to observe the demonstration park many times. This feed machine and its pellet feed have been gradually recognized by everyone. According to the request of KIPOPO National Fisheries Research Institute, the expert group has carried out regular, fixed-point and quantitative feeding experiments in the fish ponds of KIPOPO to improve feed utilization. Except the more than 400kgs of pellet feed provided, more than 50 breeding workers were trained. At present, the expert group is working on a new feed machine for their cooperation partners (the jack is provided by the other side). The expert group has applied for project funds and plans to remanufacture 5 feed machines for the surrounding farmers.

2. Build fish cage

In order to support the export group in building cages and start the Fish Cage Culture as soon as possible, Zhang Shengguan, General Manager of Huayou Demonstration Park purchased a batch of cage construction materials from China which will arrive in May.

The first step of building fish cage is to build a working ship. Under the guidance of the expert group, the staff of the demonstration park took 13 days to build a 6-meter-long and 1.1-meter-wide vessel with two sealed boxes inside. Expert Zou Deliang painted “China Fisheries” on the hull.

On June 28, the “Chinese Fisheries” ship was launched and completed the construction of four cages (4*3*2m) and two seeding cages (2 of the 4 grids are recyclable, in fact there are 6 cages) within two days. During the construction, the expert group used bamboo as the frame to simplify the project and reduce cost. At the same time, 14 local experts and aquaculture workers were trained. The Chinese technicians taught hand-in-hand the knowledge about the thickness and length of the bamboo, the size of the bamboo joint, the occlusion of the tenon and the occlusal fixation and the determination of the net cage distance as well as the knot of net track, and explained patiently and carefully until everyone is familiar with it. Engineer Anasta is interested in aquaculture, especially the Fish Cage Culture and said excitedly:” I have learned to build cages and I’m looking forward the opportunities to learn the Fish Cage Culture from Chinese technicians. In the future, during my favorite fish-farming career I will help to develop the regional aquaculture.”

On July 4, the Expert Group introduced the whole process of building cages on the worksite to the experts of the first phase evaluation group and received unanimous praise.
