The treasure found on the beach!

The question was; "What do you think this is, what treasure is inside it"?

Well here I will give you the answer!
But first a few more clues!

This gull also finds great benefit from a part of the treasure as they love to eat the scraps!

Another clue this stinky slippery mass below had top parts of it cut open to remove it's treasures!

Let's have a look at how they remove the treasure.

First a deft cut with a knife by this lady!

Phew! The smell can make weaker souls faint!

And here it is. This stuff in the picture below is called "Red Bait" some call it "Red Gold" and it is used by anglers to catch South Africa's prime National fish!

But what is "Red Bait"?

"Sea squirt, also called ascidian, any member of the invertebrate class Ascidiacea (subphylum Urochordata, also called Tunicata), marine animals with some primitive vertebrate features. Sea squirts are primarily sessile (permanently fixed to a surface), potato-shaped organisms found in all seas, from the intertidal zone to the greatest depths. They commonly reside on pier pilings, ships’ hulls, rocks, large seashells, and the backs of large crabs. Some species live individually; others live in groups or colonies".

Can you believe that some of the 3000 species have anti-cancer properties?
They are used in bio-medicines!

The fish here below is a "Galjoen" our national symbol and they are only found on the southern coastline of South Africa.

Here in the link below you can read all about this famous fish that can change its colors.

"What is a galjoen anyway?
Galjoen are a mid-sized fish, with oval-shaped, flattened bodies with symmetrical dorsal and anal fins giving them a distinctive "Snapchat logo" shape, especially when they raise their spines in defence. Although usually a dark near-black, they are able to change colour. Most are nearly-black, helping them to blend into the rocky coastlines they prefer, but they can change to pale bronze when around the coast. Occasionally, they are also able to display vertical stripes. They are known to grow to about 7kg and over half a metre in length, but this large size is rarely reached due to fishing pressures".

There is also another treasure on the beach to catch Galjoen!

See this differently colored pod below?

Turn it over and split off the colored part!

This below is called "Black Bait"

When it is squeezed it releases a liquid cloud in the sea water that attracts the Galjoen fish!

In the bucket below you can see the difference in color between the Red Bait, left, and the Black Bait, right!

This is the cast off, waiting for a sea bird to collect it!

The life of a fisherman is to know the sea, its tides and its secrets. To live and breathe the sea!

The little guy here will maybe become a fisherman just like his father who is preparing his bait here for the evening high tide fishing event.

I was also going to put a video in here that details the baiting of a hook with the "Red Bait" as it is done in a special way, but this post is already too long.
I prepared 10 photos for each of the Red Bait and Black Bait sections, but then decided to cut it only to the basics.

Unfortunately we didn't have a winner of the offered 2 Hive here, but the next time that I do this, I will make the question easier.

Note: All photos, except the cited "Galjoen" picture are my own, unedited and cropped for uploading purposes.
All sections of words in ("") inverted commas are not my own and were duly source cited!
