What we DO

Threats in the ocean

A rapid increase in the world’s population, as well as industrial and technological innovations, has caused the demand for marine products to rise since the 1950s, a demand that even the rapidly expanding aquaculture sector cannot meet.


Our Vision

Provide migratory marine species of the Eastern Pacific with a threat-free environment to guarantee the health of their populations over time.

Human activity, such as fishing, is the greatest direct threat to the migratory marine species in this region of the ocean. However, there are other threats that affect them indirectly and that are generally of anthropogenic origin.


More than 50% of the involuntary mortality of marine species has to do with the fishing interaction.


A low rate of reproduction and late sexual maturity make some species very vulnerable to overfishing.


Species are caught unintentionally when they become entangled in fishing gear, such as nets and lines, used to catch commercial species.

Artisanal fishing

Sometimes, due to cultural traditions, local communities hold rights to catch endangered species

Habitat degradation

The accumulation of plastics has generated 5 large islands two in the Pacific, two in the Atlantic and one in the Indian.


The dumping of plastics and waste is one of the major causes of the deterioration of marine ecosystems.

Loss of breeding areas

Urban development contributes to the disappearance of beaches and mangroves which are used as nesting and breeding sites for turtles, sharks and other fish.

Invasive species

The arrival of species from other ecosystems very often displaces the native species of an area.

Climate change

Since around 1850, the oceans have absorbed between a third and a half of the CO2 emitted to the atmosphere.

Redistribution of species

Changes in water temperature may cause changes in the geographical distribution of different species.

Influence of El Niño

This atmospheric phenomenon has its origin in the Pacif- ic area and its effects are especially noticeable in this region.

Migration routes

Changes in oceanic currents may alter the migration patterns of different species, as well as availability of food (prey).

Illegal actions

Without rules, we cannot protect biodiversity and marine life.


Cutting the fins off live sharks in order to sell them on the Asian market is one of the major threats.


Taking turtle eggs for food makes recovery of these populations more difficult.

Illegal fishing

The difficulties involved in the control of a marine reserve make it easy for some fisher- men to illegally enter protected areas to catch fish.

By understanding the consequences that the decrease or even disappearance of marine species can bring, helps us maintain healthy aquatic ecosystems, reduce their threats and therefore maintain the human activities that depend on them.

The need of reliable scientific information There is a critical need for reliable scientific information for conservation and management policies. Generating sustainable forms for economic activities that depend on the oceans as well as ensuring the well-being of marine ecosystems is necessary; only by working together and breaking national barriers, we would effectively protect these species.

Migramar as well as providing information referring to the migratory pattern of species such as sharks, sea turtles, manta rays, bone fishes, etc. Is a source of scientific information which permits the assessment and prediction of the state of their population in the future. Migramar divides its work into two areas:
