Chlorophyll Imagery

[Mithras]

Hi all

I've been slowly learning more and more about fishing the open ocean. How do I read the Chlorophyll imagery? How does this affect where the fish is?

My understanding is that Chlorophyll is the result of plankton, and areas with higher levels of Chlorophyll means there is more food, and more likely to hold the fish due to the food chain being more relevant in that area

Am I far off the mark?

What is the benefit then of very clean water with low Chlorophyll levels? Would one not want to stay away from this water?

Thanks in advance

My understanding is that Chlorophyll is the result of plankton,

Not quite. Chlorophyll is a constituent part of phytoplankton. ( plant like) It allows them to use sunlight to create food.

This just makes up part of all plankton with zoo plankton ( tiny animals) and other types making up the rest.

They are the base building block for the food chain.

Depends what you are chasing when I am chasing tuna I look for low chlorophyll, but when chasing Marlin I prefer high chlorophyll.

Tuna seem to dislike dirty water.

Yes chlorophyll is an indication of what is termed primary productivity as the carbon fixation by phytoplankton is the basis of the food chain. It can be measured by sampling or sattelite imagery and can be used to compare the productivity of different ocean regions.

Great. appreciate the help guys.

i've paid for a premium sst site, so getting more information that i'm not sure what to do with.
