Hundreds of striped mantas they approached this Wednesday the shore of Biscayne Bay (Biscayne Bay) of Miami reportedly looking for oxygen, according to the environmental organization Miami Waterkeeper a day after thousands of dead fish were found floating.

“Today, the Pelican Harbor seabird station reported an agglomeration of stingrays just offshore. Scientists believe that (…) may be due to low oxygen levels in the water, which makes it difficult for the stingrays to breathe, “the NGO said on its Facebook portal.

“(State) agencies are working on a quick response to avoid streak extinction in this area, “he added.

Dead marine animals and fish

The environmental organization, which is compiling citizen reports on dead fish “to understand the scope of the problem,” says “since the beginning of this week.” dead fish and other marine animals have been seen from north of Miami to Virginia Key, an islet near the port of Miami.

Pending the Florida Fish and Wildlife Conservation Commission (FWC) this weekend to release the laboratory results of the samples that Miami Waterkeeper has sent you, this NGO continues to alert that “nutrient contamination” may be the cause of massive death of marine species.

“This fish death is likely caused by a low dissolved oxygen event, although we are still investigating. Dissolved oxygen is the amount of oxygen available to all living things in the water, both plants and animals,” he said Miami Waterkeeper in a statement.

Algal blooms can lead to low oxygen conditions (…). These blooms can be caused by too many nutrients like phosphorus and nitrogen in the water. Nutrients like these can be found in sewage, septic tank tributaries, fertilizers, pet waste and storm water runoff, “he added.

Our researchers do not know the cause of the death of marine animals but they suspect the low oxygen level

FWC, the highest state environmental authority, said yesterday in a statement that “our investigators currently do not know the cause of death; they suspect low dissolved oxygen. We are working with the Miami Waterkeeper team to collect water samples and obtain more information. “.

The bad smell emanating from the water has been a widespread complaint of the residents of areas near the bay. Meanwhile, FWC has asked users to use an available app to submit information such as water discoloration, affected species and other environmental conditions, as well as photos.
