Keri's+Third+Visit

I went on Sunday, November 9, at 1:00 pm.

On my third visit, I went during high tide and I saw more species of fish in the water that were different from last time. I saw aholehole, weke, mamo, papio, and kole. I think that these fish come inside the inlet during high tide and go back out to sea during low tide. It was very windy; the winds were blowing about fifteen to twenty miles an hour. The water was very choppy and there were bigger waves than the last visit. As I mentioned before, it was high tide and the depth of the water was about five to ten feet deep. The temperature of the water was about the same: cold.

In the last journal, I mentioned that the fish were noticeable and wondered why they were. I infer that the fish don’t have major predators because there’s a lot of brightly colored fish in the inlet, swimming peacefully and happily.

I also wondered why the fish preferred living in the high currents, which is at the mouth of the inlet, rather than the low currents. I infer that the fish need the high current to breathe because the rapid water would flow right through the gills of the fish and there’s probably more dissolved oxygen in the rough water. The high current also helps the fish to find food because the rough water stirs up the bottom and there is more organic matter floating in the water for the fish to easily eat.

Why are the fish generally small? I infer that the small fish live in the inlet, where they can eat and hide in the rocks, and when they are too big to hide, they eventually move to the ocean.

I asked why all the fish swam along the sides of the inlet and none in the middle. I infer that there is more food for them to eat along the sides than in the middle because there’s only sand and no plant life in the middle and along the sides there’s plenty of reef and plant life. Also, I think there’s more protection for the fish along the sides because they can hide in the rocks; there’s no protection for the fish in the open area in the middle.

I also asked why the fish swam on the bottom only and not in the middle or the top of the water. I infer that the fish go where the food goes and the food is on the bottom.

Hypothesis: If it is high tide, then there will be more various species of fish in the inlet.
