In this brief guide, we’ll focus on the search query: “What do mackerels eat?” Also, we’ll explore what mackerels are, where they’re distributed, and what their importance is.
What do mackerels eat?
Mackerels feed on small arthropods, and small mollusks and they prey on other types of smaller fish and their eggs.
Mackerels can grow to measure up to 24 inches long, and their diet may include krill, cuttlefish, squid, shrimp, anchovies, small herrings, sardines, plankton, fish eggs, and smaller arthropods.
Their diet will, of course, depend on where they find themselves at any given moment, and what foods are available.
In their younger stages, while preying on krill and plankton, mackerels may inadvertently become prey to larger animals such as whales and dolphins. They travel in schools, and as a result, draw the attention of predators that can easily consume several of them using social dynamics and hunting skills of their own.
What are mackerels?
Mackerels are bony fish that have long, narrow bodies towards the tail. They are agile swimmers and can be found in temperate waters, as well as some that are mildly balmy.
Mackerels is actually an umbrella term used to allude to fish that are long and have a silver coloring, with dark, longitudinal stripes on their bodies.
They cover vast distances in their schools and can be found in regions where animals that make up their diet are concentrated.
Despite them being abundant, both in number of species and when in schools, not all mackerels are edible. This is because some may have dangerously high concentrations of mercury in their flesh.
Breeding macros is difficult, as they are gregarious and therefore any farm would require a large number of individuals for them to thrive. As a result, many mackerels are overfished in waters where they are found in the wild.
Where are they distributed?
Mackerels can be found in temperate and balmy waters. They can be found in tropical regions and in cooler waters in the oceans. Schools are typically fished near coasts or offshore environments.
The exact distribution of mackerels will depend on the species, size of the school, and the availability of food and school shift to waters where there are more readily available resources to sustain their group.
Mackerels are pelagic. This means that they can be found in many open waters, though they remain close to the surface.
Fittingly, they can be found in both the Atlantic and Pacific oceans, and may also be found as far north as the Baltic Sea.
What is the importance of mackerels?
Mackerels are important intermediate links in the food chain. As intermediate consumers, they concentrate nutrients that they source from smaller species and make them available to larger members of higher tiers in the food chain.
As such, they are an important source of food to other fish, and predatory animals such as whales, sharks, dolphins, seals, sea lions, and on occasion, even humans.
However, in regards to fishing, we must begin to source them sustainably.
To this day mackerels are being over fish to dangerously low levels, coupled with the pressure exerted by other predators who depend on them, a decreased population of mackerels may have serious consequences on oceanic environments, and most notably, in food web dynamics.
As oily fish, mackerels that are deemed fit for consumption can be highly nutritious, due to their omega-3 fatty acid content.
Omega-3 fatty acids have considerable antioxidant activity, which provides many benefits such as helping to reduce the risk of cancer, heart disease, type 2 diabetes, cognitive disorders, and many other benefits.
Depending on the species, some countries may be stellar suppliers of mackerel meat. For example, Atlantic mackerels are supplied by countries such as Norway, the United Kingdom, and Ireland, whereas Chub mackerels are supplied by China, Japan, and China.
As a result, mackerel is an important oceanic project that provides income to many countries, as well as nourishment to their populations.
Many countries need to address the problem of overfishing and authorities need to enforce legislation measures implemented to protect these populations, to avoid environmental consequences that’ll affect more than just economies.
