 note = {Phototactic behaviour of milkfish larvae and juveniles was observed in the sea and
laboratory, and their retinae were observed histologically. Larvae collection by using a
lamp at night and tank experiments revealed that the larvae have strong positive
phototaxis. Throughout their growth, there were three shifts in phototactic behaviour
in a tank. The photopositive behaviour of the larvae became weak by degrees through
a metamorphic stage, and juveniles showed photonegative behaviour. On the 39th day
from capture, their behaviour became photopositive again. After they were transfered into a larger tkank, on the 139th day, any significant photopositive or photonegative behaviour could not be observed. The larvae on capture, have duplex retinae. The rods were found to be a few in number, and a clear retinomotor response was observed on the day of capture. The first change in behaviour from photopositive to photonegative seemed to relate with the development of the rods.},
