Octopus are one of the most intelligent invertebrates and they also have two hearts. They live in the pacific but lately there has been more octopus then there normally are due to predator scarcity and climate change.
Many cultures eat octopus regularly mostly in Asia but there is never really a big demand for octopus around the world. Lately it is considered to be sustainable to eat octopus because of their over population.
This Statistic shows that octopuses are third level carnivore consumers. Sharks eat octopus as well as dolphins and sea lions and those animals grow at a slow rate and if there is not many of them then there will be more population for the octopus.
Behavior of the mimic octopus is extremely significant in how they adapt to predators and how their strategies are to survive. Aquariums are decreasing the population of the Mimic octopus. For certain species it may good to use them for aquariums to help decrease the population.
This article exemplifies how octopuses are very adaptable to overfishing and climate change unlike other species in the ocean. Octopuses have a rapid reproduction rate and without other predators like sea lions and sharks to help maintain the population there becomes octopus blooms.
This boom started in 1997-2000 when El Nino occurred. Then the octopus, squid, and cuttlefish migrated to the pacific coasts. Octopus produce a lot of eggs and whatever environmental challenge that the parents went through they put a protective coat on embryonic mucus on the eggs then those traits enable the cephalopods to adapt rapidly to the environment.
SUMMARY: Shark population because of bycatch (the accidental fishing of some fish in hopes to get big portions of other fish they can sell). Sharks grow very slowly and if we take them out of the ecosystems it makes other populations of animals much bigger and makes it unhealthy for the ocean. SUSTAINABILITY: The news is unsustainable for sharks and the ocean in general. It is unsustainable for humans when sharks are apart of bycatch when they aren't the main fish source they need to sell. CAUSE AND CONNECTIONS: The cause of this is humans and bycatch is huge in declining many populations of other fish that have slow growing populations.
SUMMARY: How climate change and overfishing are the causes of these blooms. Octopus are like the weeds of the ocean in how fast they grow and adapt. If there's a large number of octopus then they consume a lot which isnt good for the other species. SUSTAINABILITY: It is sustainable for octopus short term without predators because food can become scare in the future and they basically live care free. CAUSES AND CONNECTIONS: Humans are the cause of this problem in overfishing of first level carnivore predators.
One solution could be to find other ways to harvest our resources without killing other unintentional preys. There will never be a complete abolishment of bycatch but there is other intelligent ways we can choose to fish without hurting the environment.
Another solution can be organized hunting to keep that top predator category if there is scarcity of sharks. A free for all hunting spree is not what could be sustainable but if people have licenses to hunt octopus then it can reduce the population explosions. If there are licenses for octopus then maybe we can reincorporate them into our diets.
In conclusion there is an increased population of octopus because of climate change, bycatch of predators, and overfishing. Octopus are not ever going to be doomed there is hope in restoring the ecosystem if we maintain the shark populations in reducing bycatch.
