UNAIR NEWS – Faculty of Fisheries and Marine(FPK) once again contributes a research to increase the publications of Universitas Airlangga (UNAIR). This time, Muhammad Browijoyo Santanumurti S.Pi., M.Sc and his colleagues in Universitas Airlangga conducted a research on improving the quality of sperm cells in Sutchi catfish with the addition of honey.

“Our results showed that the use of 0.6% honey can be used in the cryopreservation process to support the availability of Siamese catfish seeds and encourage the advancement of Indonesian fisheries,” explained the lecturer of FPK UNAIR.

Browijoyo explained, cryopreservation is a process of preserving cells and tissues using liquid nitrogen at a temperature of -196 0 C for a long period of time without reducing biological function. The process is used to store fish sperm cells in optimal conditions so they can be used at any time for artificial spawning.

Meanwhile, honey can be used to improve the quality of conjoined catfish sperm cells in the cryopreservation process because honey contains 41% fructose and 35% glucose, and they can be used as an energy source for sperm cells.

“Furthermore, honey also contains salt ions which can be used to maintain cells during the cryopreservation process so that they are not easily damaged,” he continued.

However, the interesting thing in this study is that the addition of excess honey can reduce the quality of sperm cells during the cryopreservation process. The reason is, because too much honey can provide toxic effects on sperm cells. Thus, the most ideal use of honey for improving the quality of Sutchi catfish sperm cells is 0.6 percent.
