A trout is a predator.

Recent studies have documented the rapid decline of large predatory fish species such as billfish, sharks and tuna.

And then we have a lower biomass of carnivores, and a lower biomass of top head, or the sharks, the large snappers, the large groupers.

(v) Consumption of a small amount of fish or meat, in addition to vegetable protein, will be encouraged.

So how are these fish, these predators going to help?

And some of those whale meat samples were whale meat.

407. Compared to 1992 there was a decrease in consumption of meat products (51.8 per cent), meat and poultry (49.6 per cent), fish and fish products (46.1 per cent), confectionery products (44.4 per cent), fruit and fruit products (39.9 per cent) and butter (33.5 per cent).

This is whale meat that I photographed in a grocery store in Tokyo or is it?

In the Pacific, the biomass of large predatory fish caught by longline fishing, for example, has declined by 90 percent since 1950.

Meat or fish?

It's fish souffle.

Targeting highly migratory predatory fish species including tuna and swordfish, industrial longlines also catch or kill as many as 4.4 million sea turtles, billfish, sharks, marine mammals and seabirds.

He doesn't like fish.

Eat not only fish, but also meat.

Cats like fish more than they like meat.

Dried fish and miso soup again?

There's fish soup and roast chicken.

Remember those nice, juicy cuts of beef?

The weak are food for the strong.

The surimi sticks of crabmeat, or is being sold as crab meat, is white fish that's being dyed with cochineal.

But back to animals and junk food.

They shared a full catered meal of chicken and fish.

We could much better change from meat, from beef, to insects.

Even though they were labeled whale meat, they were dolphin meat.

Less meat, less junk, more plants.

What shall they eat?

Is there some reason you want to let that brigand keep throwing his weight around?

Here's an octopus. Sometimes they don't want to be seen when they move because predators can see them.

Most of the biomass is low on the food chain, the herbivores, the parrotfish, the surgeonfish that eat the algae.

As awareness grows, levels of consumption of large predatory fish such as tuna and swordfish are dropping.

But some of them were not whale meat at all.

Do you want the chicken patty with the cream sauce or fillet of sole?

They have sorts of ingredients that you brush on a piece of chicken or fish, and it turns it to look like beef.

A big treat, with sirloin meat, fish loaf, green onions and prawns.

You will see that my piranha fish get very hungry.

I remember sitting at my desk being about the only person in the world who knew that whale meat being sold in these markets was really dolphin meat, and it was toxic.

Another scientific study showed that in the Atlantic large predatory fish biomass today is only about 10 percent of pre industrial levels.

Who needed it though? Meat was everywhere.

They used to use the flesh as well for fertilizer and also would fin the sharks.

So the key now is to make it behave like tuna.

Prey to these cursed creatures, these horrors, these gorgons.

That animal feeds on flesh.

Always leave the lights on.

The predator smells the bait, sneaks up... and he's caught!

First I get fish, then chicken, then comes lamb.
