The choice of bait directly impacts the breeding and growth of clams. Whether or not scientific feeding can be implemented is a crucial technological factor that determines the growth rate and quality of seedlings. To this end, we will introduce a scientifically structured feeding strategy tailored for seedling cultivation. Like other aquatic organisms, feeding should follow four key principles: qualitative, quantitative, timing, and positioning. However, each of these aspects in seedling cultivation has its own unique characteristics.
First, the qualitative aspect of feeding.
Seedlings require more than just energy to increase their body weight—they also need various nutrients and energy to support the development of different functional organs in their bodies. As a result, the quality of feed is especially important. While there are many commercial feeds available on the market, they are often processed through multiple mechanical steps, which can lead to the loss of some highly active nutrients. Therefore, it’s essential to supplement commercial feed with additional nutrients that are vital for the growth and development of seedlings. These can include fresh carrots, eggs, calcium milk powder, fresh fish, and red worms, among others. The added amount should be between 5% to 10% of the daily dry feed. Before adding, these ingredients should be blended into a pulp or crushed and mixed thoroughly into the commercial feed to form pellets before being given to the seedlings.
Second, the quantitative aspect of feeding.
Seedlings should be fed in a way that ensures they eat well without overfeeding. It’s not about filling them up completely, but rather maintaining an optimal feeding rate. A bait rate of 5% is generally recommended. Although this may seem high, the actual quantity remains manageable, minimizing waste and water pollution. For example, if a pond covers 20 square meters and the average weight of each seedling is 4 grams, totaling 2000 grams, a 5% feeding rate would equate to 100 grams. Even if some is wasted, it only amounts to 100 grams. At this stage, the goal is to encourage a strong appetite in the seedlings. The actual feeding amount should be adjusted by ±5% depending on how much the seedlings actually consume at each meal.
Third, the timing of feeding.
Timing refers to both the frequency and the schedule of feeding. Due to the delicate nature of seedlings, it's best to feed them frequently in small portions. Ideally, feeding should occur four times a day—around 5 a.m., 10 a.m., 3 p.m., and 8 p.m. Each feeding session should last approximately one hour, during which time you should observe how much the seedlings eat to determine the next feeding time.
Fourth, the positioning of feeding.
Positioning refers to where the food is placed. Currently, 1.8x1 corrugated high-quality cement tiles are used as feeding plates. To help the seedlings collect food efficiently, it’s recommended to place one cement tile per 200 seedlings. When feeding, the food should be spread evenly and accurately onto the feeding plate to ensure accessibility and minimize waste.
In addition to serving as feeding stations, these cement tiles also provide a suitable habitat for the seedlings, helping to maintain a clean and organized environment for their growth.
