The American Soybean Association, in collaboration with the Heilongjiang Fisheries Technology Extension Station and the Shenyang Fisheries Research Institute of Liaoning Province, conducted a series of pond breeding experiments to evaluate the economic viability of raising highland herring using high-protein soybean meal. These trials took place in both Heilongjiang and Liaoning Provinces in 2006, aiming to assess the growth performance of second- and third-instar fish as well as the overall efficiency of aquaculture practices among local fishermen in northeastern China, using feed with a 36% crude protein content.
In 2005, similar trials were carried out in Anhui and Heilongjiang provinces using the American Soybean Association-International Project 32/6 soybean meal feed, which was designed for species like salmon, squid, tilapia, and channel catfish. However, the results showed slower fish growth, less efficient feed conversion, and unstable economic returns when used for herring. This prompted researchers to suggest increasing the protein level in future feed formulations to enhance growth rates and feed utilization in herring.
Based on these findings, two additional culture experiments were conducted in 2006 to test the effectiveness of the 32- and 36/7-type feeds from the American Soybean Association-International Project for rearing 2- and 3-year-old herring. The 36/7 feed is typically used for fingerlings up to around 50 grams and contains higher levels of crude protein and fat compared to the 32/6 feed, which is more suitable for adult fish (see Table 1–3).
The 2006 herring cultivation experiments lasted between four to five months, depending on local water temperatures and weather conditions. At harvest, data on survival rate, total yield, net yield, average fish weight, and feed conversion ratio were collected. To ensure accuracy, all fish in each of the three experimental ponds were counted and weighed. Herring and trout were sampled to estimate average body weight. Additionally, all input costs for each trial were documented to calculate the economic benefits of using high-protein soybean-based feed in herring farming.
