  • A Study on Measuring the Educational Effectiveness of an Aquaponics STEAM Program Using Food Residues

    Project Period (FY): 2022/04  -  2025/03  Investigator(s): 佐々木 剛

  • Studies on the development of non-fishmeal/non-fish oil feed for sustainable aquaculture

    Project Period (FY): 2019/04  -  2023/03  Investigator(s): Satoh Shuichi

    Grant-in-Aid for Scientific Research(B)  Co-Investigator  19H03047 

    Basical research for development of non-fish meal/non-fish oil feed for marine fish was conducted to develop the sustainable aquafeed. Marine fish require EPA and/or DHA as essential fatty acids. Therefore, non-fish meal/non-fish oil feed for marine fish was developed by using the dried powder of Schizochitrium which is micro algae rich in DHA. Firstly, a feeding experiment was conducted by using the experimental diet formulated with Schizochitrim powder at the level of DHA requirement. After a feeding trial, identical result was obtained between fish meal/fish oil based diet and non-fish meal/non-fish oil diet with Schizochitrium. A similar kind of experiment was conducted with yellowtail, however, palatability of the diet was too weak to grow. Thefore feed stimulant supplementation improved the feeding activity and resulted a similar growth as fish oil diet.

  • Studies on the development of aquafeed with consideraton of rearing condition and low load to environment

    Project Period (FY): 2014/04  -  2019/03  Investigator(s): Satoh Shuichi

    Grant-in-Aid for Scientific Research(A)  Co-Investigator  26252034 

    The project was conducted to decrease the load from aquaculture site by developing the non-fish meal and non-fish oil feed for fish, and surveyed the optimal condition for rearing. As protein sources, soybean meal, corn gluten meal, and soy protein concentrate which contain low phosphorus are considered to suitable. As lipid source, schizochytrium meal is considered to be suitable because of high docosahexaenoic acid contents. It was succeeded to develop the non-fish meal and non-fish oil feed for red sea brea by formulate plant protein sources and schizochytrium meal.
