Why can't we catch many Barramundis in September?
In the case of our land based fishing
Around the east region of Darwin City

We can catch many Barramundis in July around here.
We can catch many Barramundis after the second half of October.
But we can't catch many Barramundis in September around here every year.

Why?

There should be two reasons.

The reason 1:
The temperatures are developing.  But those conditions are very unstable in the day time and the night time and there is a big difference, especially the second half of August and early September.  It produces some different waters around here.
This phenomenon of different waters is caused by the land shape patterns and the submarine topography patterns.
There is a very big tidal movement in Darwin and so you probably hardly agree with me.
It is thought that Barramundis are staying in their more comfortable water now.
Therefore, its population itself is much smaller than the other season around here in September.

The reason 2:
It is thought that there is an influence of the water through the tidal flats in this season.
Even if we see a Barramundi in the water, Barramundi doesn't take a lure.
It is thought that Barramundi isn't hungry.

When you walk on the tidal flats around the east region of Darwin city.
You can see the different conditions of mud in every season.

Rainy season: No mud on the shore (Washed out - Muddy water)

Dry season: Not thick mud on the shore (Clear water)

September: Very thick mud on the shore (Unstable waters)

Wet season: Some rains (More stable waters)

Rainy season, Dry season and Wet season are very good for our land based Barramundi fishing.
Muddy water itself is very good for catching Barramundi.
This muddy water means that the water colour is more likely muddy.
It doesn't means the quality of the water.
We shouldn't misunderstand that mud itself is a negative factor for our land based fishing.

The temperature is getting hotter day by day in September.
And you can see a very interesting condition of mud on the tidal flats in September.
The mud expands with heat in outgoing tide on the tidal flats in the day time.
It comes to approx. 50mm thick.
It smells something decomposing.

It is thought that the water through the tidal flats with this negative organic matter diminishes Barramundi's appetite.
Barramundi doesn't want to take lures under the condition of the influence of this water in September.

It is thought that these factors of the water temperature, something positive or negative organic matter and their life cycle of Barramundi are a combination of many separate factors, each of which is related to, and affected by, the others.

There is no validation of this.

In my conclusion,

It is thought that we can catch many Barramundis even in September if we find the water without the influence of this negative organic factor.  However, the water should be more stable condition in water temperature there.




Probably, something negative organic matter should be too much for Barramundi in the water on the shore in September.  Some rains will break the spell of this negative organic matter.  And we will have some fish bites when we have had no rainy for 24 hours.
