Chile algal bloom kills 170,000 salmon, raising concern

SANTIAGO, Feb 9 (Reuters) - An algal bloom killed some 170,000 salmon in recent days in Chile, the world’s second-biggest exporter of the fish after Norway, as they were being transported by boat, raising concern about an industry that was devastated by an outbreak last year.

The current algal outbreak is not located near any of the salmon farms that dot southern Chile’s coastline but has infested sections of the shipping lanes used by producers, the government’s fisheries Sernapesca body told Reuters on Thursday.

Harmful algal blooms happen when the normally occurring aquatic plants grow out of control and produce toxic effects on fish.

Live fish being transported by local producers Australis Seafoods and Nova Austral were infected and killed earlier this month. The boats, which recirculate ocean water into the tanks to keep the fish alive as they are transported, inadvertently passed through the infested waters, Sernapesca said.

“Warm weather and little rain were some of the reasons for the algae bloom last year, and Chile has experienced some of the same weather this year,” broker Pareto said.

Last year, an algal bloom killed up to 20 percent of Chile’s farmed salmon, some 25 million fish, pushing prices higher globally.

Part of the fish being transported were headed for harvest and others were tiny smelts that were going from fresh water to cages in the ocean.

A flyover on Wednesday by Chile’s navy and Sernapesca could not visually locate the algal bloom, which has a distinctive color, the government body said. (Reporting by Anthony Esposito; Additional reporting by Ole Petter Skonnord in Oslo; Editing by Cynthia Osterman)
