| The stable supply of genetically and physiologically high quality seeds of aquatic organisms is one of the most important issues for the aquaculture industry. The Aquaculture Biology Division takes charge of research on the biology of aquatic animals and plants, aiming to develop techniques of breeding and stable seed production for aquaculture | ||
 Normal |
 Short trunk |
 To provide the strains which have good performance of growth and disease tolerance, we investigate the breeding technology such as selective breeding, hybridization, chromosome manipulation, and DNA recombination of aquatic organisms. This group also takes the role of the center bank of the Fisheries Research Agency (FRA) Gene Bank. |
 Pale color |
 Mirror inversion (situs inversus) |

| Japanese flounder strains which show different appearances. | ||
 High temperature （30-35℃） tolerant strain of micro- algae Chaetoceros gracilis. |
 Researches are focused on maturation and its artificial control of aquatic animals for which eggs and sperms are difficult to obtain. Our research is also focused on the elucidation of normal embryonic and larval development of various species, to produce healthy seed for aquaculture. |

 First success to rear eel larvae to the glass-eel through the leptocephalus stage (Numerals show days after hatching). |
 Juvenile eels which were obtained under completely artificial conditions. |
