The river shrimp fishing season nationwide will be extended exceptionally until January 2, 2018 based on the recommendation of Instituto del Mar de ​Peru (IMPARPE), informed the Ministry of Production (PRODUCE).

The ministry recalls that the fishing season of this shrimp (Cryphiops caementarius) takes place in the period between April 1 and December 19 of each year, but the date can be modified based on IMARPE recommendation, as it is the present case.

According to Ministerial Resolution N° 616-2017-PRODUCE, published in the official newspaper El Peruano, as of January 3, 2018, the catch, processing, transportation, commercialization, use and consumption of the river shrimp will be banned in the national area.

IMARPE report was based on the results of the "Analysis on the reproductive condition of the adult population of the 'shrimp' Cryphiops caementarius in Arequipa rivers", which concluded that, for example, the period of maximum reproductive activity of shrimp has not yet started in these rivers.

Likewise, it indicated that assuming what is defined in the shrimp reproductive pattern in the rivers of Arequipa region, there is evidence of a slight delay in the process of gonadal maturation of the resource.

Therefore, the report recommends that according to this small delay in gonadal maturation, it can be considered to establish the reproductive ban of river shrimp at the beginning of January of next year.

IMARPE points out that the river shrimp is the only hydrobiological resource of the Peruvian coastal rivers that supports a commercial fishery. The fishing activity on this resource has been increasing in such a way that it gives it an exceptional socioeconomic importance in the area of ​​its influence.

At present, the populations of the resource are diminishing in the smaller basins of the western slope, among other factors due to the intense catch that it supports. This excessive catch, besides physical alterations of the channels and chemical changes of the water, does not allow an adequate stock renewal.

The measures adopted to administer this crustacean have focused, mainly, on the annual establishment of closures during the period of greatest reproductive activity. These measures are based on the performance of captures to verify the reproductive condition in the rivers of the department of Arequipa.
