The number of dead seals found along the coast of Namibia has risen to more than 7,000, non-profit group Ocean Conservation Namibia said on Friday.
OCN said last week thousands of dead seal pups had washed ashore at Pelican Point peninsula, a tourist destination known for its colony of seals and shoal of dolphins.
Naude Dreyer, a marine biologist at OCN, said researchers in the past week had detected a spike in the number of dead female adults.
“What we have been observing is less freshly dead seal pups and a lot of dead female adults,” he said
He said investigations had mainly centred on the Pelican Point Beach, so the overall number of dead seals could be higher.
The Ministry of Fisheries and Marine Resources said last week it would send samples to South Africa to determine the cause of death. Dreyer said this had not yet been done because of the need to observe strict guidelines on shipping dangerous animal products.
“We are trying our best to find answers given the complex nature of the investigations where we don’t even know what we are looking for,” he said.
OCN said last week starvation was the most probable cause because fish, the seals’ main source of food, have moved from Pelican Point, but other reasons could be toxins or disease and no explanation could be ruled out without a full study.
The ministry was not immediately available for comment.

UK's plans to cut net migration
Under the UK government’s proposals, migrants will have to spend 10 years in the UK before being able to apply for citizenship.
Skilled worker visas will require a university degree, and there will be tighter restrictions on recruitment for jobs with skills shortages.
But what are described as "high-contributing" individuals such as doctors and nurses could be fast-tracked through the system.
Language requirements will be increased for all immigration routes to ensure a higher level of English.
Rules will also be laid out for adult dependants, meaning they will have to demonstrate a basic understanding of the language.
The plans also call for stricter tests for colleges and universities offering places to foreign students and a reduction in the time graduates can remain in the UK after their studies from two years to 18 months.

'THE WORST THING YOU CAN EAT'
Trans fat is typically found in fried and baked goods, but you may be consuming more than you think.
Powdered coffee creamer, microwave popcorn and virtually anything processed with a crust is likely to contain it, as this guide from Mayo Clinic outlines:
Baked goods - Most cakes, cookies, pie crusts and crackers contain shortening, which is usually made from partially hydrogenated vegetable oil. Ready-made frosting is another source of trans fat.
Snacks - Potato, corn and tortilla chips often contain trans fat. And while popcorn can be a healthy snack, many types of packaged or microwave popcorn use trans fat to help cook or flavour the popcorn.
Fried food - Foods that require deep frying — french fries, doughnuts and fried chicken — can contain trans fat from the oil used in the cooking process.
Refrigerator dough - Products such as canned biscuits and cinnamon rolls often contain trans fat, as do frozen pizza crusts.
Creamer and margarine - Nondairy coffee creamer and stick margarines also may contain partially hydrogenated vegetable oils.
