In period no. 2 of the calender of the year in Keiti we have:

 

 

There are three fishes: the shark and then two 'ordinary' fishes. All have their heads upwards. I think this idicates ascending from the deep. If the year (or in general: the period) starts at the bottom, at sun solstice (or at new moon etc), then things will go upwards.

 

The two birds at left are interesting: they do not have the usual 'splendid bird' beak, but a beak without hook. In that respect they agree with the two birds in period no. 4, the same powers up above I presume. And possibly this type of bird represents the Moon, as it appears in the place of moon in Keiti's planetary calendar.

 

There are fins in Eb2-17 and Eb2-19, which I read as flames. The sun is ascending, thats what the flames indicate, I think.

 

Fishes probably are those lights that come up from the sea, sun, moon, planets, stars.
