The ICES has released its advice on fishing opportunities, catch and effort for 2022 for pelagic stocks of herring and sprat

The ICES has released its advice on fishing opportunities catch and effort for 2022 for the Irish Sea, Celtic Sea, North Sea, West of Scotland and English Channel.

Below is a summary of the ICES advice on fishing opportunities for 2022 for pelagic stocks of herring and sprat along with a link to the full advice.

EU standing request on catch scenarios for zero TAC stocks 2021; herring (Clupea harengus) in divisions 7.a South of 52°30’N, 7.g–h, and 7.j–k (Irish Sea, Celtic Sea, and southwest of Ireland)

ICES has provided forecasts on the development of herring (Clupea harengus) in divisions 7.a South of 52°30’N, 7.g–h, and 7.j–k (Irish Sea, Celtic Sea, and southwest of Ireland). All scenarios assumed full uptake of the monitoring TAC in the intermediate year (2021), although the 2021 TAC has not yet been agreed and the full monitoring TAC was not taken in 2020. There are no catch scenarios that will rebuild the stock above Blim by 2023. ICES, therefore, advises zero catch in 2022. ICES has also provided a catch scenario consistent with the monitoring TAC (869 tonnes [t]) in the single-stock advice sheet.

EU standing request on catch scenarios for zero TAC stocks 2021; herring (Clupea harengus) in divisions 6.a and 7.b–c (West of Scotland, West of Ireland)

ICES has provided forecasts on the development of herring (Clupea harengus) in divisions 6.a and 7.b–c (West of Scotland, West of Ireland), with zero-catch TAC, with partial (1540 tonnes), and with full (4840 tonnes) uptake of the current monitoring TAC, under two different uptake scenarios for the monitoring TAC in 2021. All scenarios show an increase in spawning-stock biomass (SSB) in 2022 (17% and 21%), and a small (4% and 5%) decrease in SSB in 2023.

Herring (Clupea harengus) in divisions 6.a and 7.b–c (West of Scotland, West of Ireland)

ICES advises that when the precautionary approach is applied, there should be zero catch in 2022.

Sprat (Sprattus sprattus) in Subarea 6 and divisions 7.a–c and 7.f–k (West of Scotland, southern Celtic Seas)

ICES advises that when the precautionary approach is applied, catches should be no more than 2240 tonnes in each of the years 2022 and 2023.

Sprat (Sprattus sprattus) in divisions 7.d and 7.e (English Channel)

ICES advises that when the MSY approach is applied, catches in 2022 should be no more than 2897 tonnes.

Herring (Clupea harengus) in divisions 7.a South of 52°30’N, 7.g–h, and 7.j–k (Irish Sea, Celtic Sea, and southwest of Ireland)

ICES advises that when the MSY approach and precautionary considerations are applied, there should be zero catch in 2022.

“Now that there is a lack of quota agreement on mackerel, and Norway will not have access to fish the stock in the British zone, there will probably be extra focus and interest this summer from mackerel fishermen etc. on the mackerel’s distribution in the Norwegian Sea,” says Nøttestad.

“We at the Institute of Marine Research will try to keep relatively frequent updates about especially the spread of mackerel during the mackerel ecosystem cruise with “Eros” and “Vendla” on our  websites www.hi.no,” he says.

In the first part of the survey, Eros will take a more westerly route while Vendla follows the coast. If possible, an attempt should also be made to map the mackerel within the fjord lines in Lofoten. It has been in demand from the fisheries organisations.

This year, equipment from Deep Vision will also be tested, which has a camera and software that will be able to measure length and identify the fish without taking it on board. Read more about the technology at TEKFISK here:

The survey equipment also registers several other fish species with echo sounders, mainly Norwegian spring-spawning herring and blue whiting. These indices will be six years old after this year’s cruise. Then the time series are long enough for ICES to evaluate them, and consider including them as a knowledge base in the stock advice for Norwegian spring-spawning herring and blue whiting.

“While we are still on such an extensive voyage, we use the hay, as long as we have the time and opportunity, to monitor a number of conditions in the ecosystem. There are herring and blue whiting, horse mackerel, roe biscuits, Atlantic salmon, quail and zooplankton. From binoculars to a microscope, in other words,” says Nøttestad who will also keep an eye out for mackerel sturgeon on the cruise.

“There are many research orders both nationally and internationally that we are asked to carry out during this cruise. This year, as last year, we will notice a total of 200 roe biscuits on board “Eros” and “Vendla” to study the migrations of this exciting species.”

Furthermore, this year the focus will be on collecting otoliths (ear stones) and genetic samples for new methods to separate different herring populations, own investigations of the parasite Kudoa thyrsites which gives “jelly mackerel” and quality of mackerel, and collection of mackerel in the Norwegian Sea for genetic identification of the stomach contents of the mackerel.

In addition, there are extensive studies of sea temperature, currents and other environmental conditions.
