Freshly caught Peruvian anchovy and mackerel

Did you know that anchoveta and mackerel are like the superstars of the sea? They're super important for the whole ecosystem. These tiny but mighty fish are the favorite food of tons of marine animals, from birds to big fish. Imagine they're like the producers of a huge seafood factory. My point in this case is about their colors! let's see the blue hues!

Both are super important for the ecosystem, but each has its own way of living.

What a beautiful color pattern!

Lower selectivity can help heavily exploited fish populations

Highlights
•Selective pressure-induced negative changes on fish populations can be mitigated with lower selectivity, favouring functionality and population recovery.

•The strong selectivity on individuals of a heavily exploited population can adversely affect the reproductive capacity of the population, the recruitment, the population structure stability, among other key characteristics.

•Within an exploited population the genetically-determined individuals to mature at larger size (and reproduce when they are older), are natural candidates to gradually disappear with the current fishery approach, and within the framework of the classical measures of protection (e.g. the criterion of minimum length of catch).
