Toronto is my home town too but, I ran away over 40 years ago.
The subject of lunar and solar influences on the earth and it's inhabitants is one that has had me fascinated for a long time. Good luck on your research. Observation is the best teacher but, I'm not observant enough to put all the factors together. Give you an idea. A long time ago I wanted to measure the distance to the moon and finally assembled the equipment to do it about fifteen years ago. Did you know that it moves in four directions and each movement varies constantly on long and short cycles? As I said, fascinating.
Most of what I learned about spearing fish is easy to explain.
If you dive today and it's good, you didn't miss a good day. If not you can try again tomorrow. The more you dive the better your chances.
Fish seem easier to catch (hook and line) when currents are strongest but for me, most are speared after they eat, at slack tide and in quiet conditions. Five times I was in calm, very shallow, undisturbed water at low slack tide and saw numerous large fish. Crayfish and lobster did this for me too.
Some places attract fish more than others and the first one there (or the last) has the best chance of shooting them. Watching the fish or other divers and fishermen is the only way to find these spots. Make sure that you can find your way back.
All fishermen are superstitious and it biases their observations.
All fisherpersons are liars, except you and me.
Many people (especially athletes) are good in spite of what they do or how they train, not because of it. If you stumble along and experiment a lot, you'll come up with something that works and it can be fun. If you want to see how good you can be, get some help to come up with a seven year plan. That's how long it takes.

P.S. I like the signature. I first heard it as a he-who.
