Live fish close to shore not strange: MFMR

SWAKOPMUND, 09 FEB (NAMPA) – The Ministry of Fisheries and Marine Resources (MFMR) clarified that the recent event in which thousands of horse mackerel were trapped on a rock at Swakopmund’s Mile 8 was not alarming.
This comes after a video of a group of people collecting large numbers of live horse mackerel fish along the Mile 8 rocky reef at the beginning of the week emerged on social media.
A media statement issued by the ministry on Friday indicated that it is not a strange phenomenon to observe marine organisms, particularly fish, on the beach or alive in pools on the shore and that fish can go wherever and whenever the conditions in the sea allow or force them to go.
The ministry nonetheless highlighted that suspected conditions which could lead to this occurrence include local environmental changes in the chemistry of the seawater to levels intolerable to the fish, such as sulphur eruptions and/or anoxia (oxygen deficiency) or simple fish behaviour.
“From results from observatory scientific findings, it was evident that there were no indications in the course of the past few days, that environmental conditions affecting fish species negatively occurred,” it noted.
The statement added that phenomena of this nature are very common and many may occur unnoticed as there are very few inhabited areas/settlements along the coast.
“The parameters that were monitored are temperature, oxygen and sulphur concentration in the water and none of these parameters called for any concern,” said the ministry.
