Sea temperatures may seem bracing for swimmers, but shoals of warm water anchovies have appeared in large numbers off the south-west coast.
“Astonishing” is how Kerry-based fish expert Dr Kevin Flannery describes the volume of tiny oily fish, widely used in Mediterranean cooking.
Flannery estimates that at least 1,000 tonnes of anchovies has been landed into south-west harbours over the past week by a number of Irish vessels fishing in Dingle Bay and off the Cork coast.

Small numbers of anchovies have been identified in Irish waters before, with the first record being off Ventry, Co Kerry, in 1870. The fish also appeared off Crookhaven, Co Cork last January.
“We thought of them as vagrants, whereas this past week has seen astonishing numbers,” Flannery said.
“There is an urgent need for the Marine Institute to analyse this and establish if it is a permanent trend, where perhaps the anchovies are displacing herring,” he said.
“There is also an urgent need for Bord Bia to develop markets for Irish boats catching these fish because at the moment there is no market and trucks are taking them for fishmeal,” he said.
Peru has one of the world’s largest anchovy fisheries, and the popularity of the fish as a pizza topping, in salads and with olives has increased the value of the catch.
EU quotas for anchovies have been set for Atlantic areas, mainly in the Bay of Biscay and west of Portugal, and there is no quota in Irish waters –making it an open fishery, according to the State’s Sea Fisheries Protection Authority (SFPA).
“The SFPA is aware of the presence of these vessels in the Dingle area and is monitoring their activities in line with relevant regulations,” it said.
The Marine Institute said that it was aware of anchovies appearing in these waters in small numbers since 2003, and picked them up as part of its periodic groundfish surveys.
However, it said there was no evidence to date of abundance, or of spawning in Irish waters.
The Irish Whale and Dolphin Group noted that sending the catches for fish meal was a “poor use of forage fish”.
The Irish South and West Fish Producers’ Organisation said it was “wonderful to see these fish returning to our shores, and will give a big needed boost to our fishermen after the terrible year they have suffered from storms and collapsing markets due to the Covid pandemic”.
Anchovy are a species with a “low vulnerability and high resilience and as such can sustain high levels of fishing pressure,” according to the Marine Conservation Society.
“Recruitment of young fish to the stock is affected by environmental factors including climatic fluctuations. If recruitment is low and fishing pressure too high the stock becomes vulnerable to collapse,” it says.
“Anchovy are also a species at or near the base of the food chain and the impact of their large-scale removal on the marine ecosystem is poorly understood,” it says.
