Proposed Marine Planning Zones Extension (0-12 nautical miles). 

Marine planning zones set out the spatial limits for particular local authorities responsibilities for planning controls of marine fish and shellfish farms in Scottish waters. Scottish Government are proposing that marine planning zones are extended out to 12 nautical miles to resolve a gap in aquaculture planning regulations. These proposals go through a public consultation which opened on 18th September 2024 and closes on 11th December 2024.

This layer displays the proposed marine planning zones extended out to 12 nautical miles.

Salmon Fishery District boundaries used by Scottish Government Marine Scotland for reporting annual statistics obtained from salmon catch returns made by the owners, occupiers and agents of salmon fisheries. There are 109 Salmon Fishery Districts (SFD) – see information on the layer fields below.

Salmon Fishery District boundaries were derived by Scottish Government Marine Scotland from Scottish Environment Protection Agency (SEPA) 1:50,000 river catchment boundaries, Institute of Hydrology 1:50,000 DTM data and the Salmon Fisheries (Scotland) Acts 1862-1868, with some input from District Salmon Fishery Boards.

Salmon Stock Assessment Areas boundaries, used by Scottish Government Marine Scotland to demarcate rivers where salmon stocks are assessed under the Salmon Conservation (Scotland) Regulations 2016. The regulations are amended annually to introduce measures for protecting stocks. Salmon Stock Assessment Areas are also used for reporting annual statistics obtained from salmon catch returns made by the owners, occupiers and agents of salmon fisheries. See links on the Statistical boundaries page for more information on the annual assessment, river grades and salmon stock management. 

Salmon Stock Assessment Areas are a subset of Scottish rivers, where there is sufficient information on salmon stocks in rivers, or groups of rivers, that their status can be assessed annually and graded for the subsequent fishing season. There are 173 Salmon Stock Assessment Areas (SSAA), made up of 215 individual or grouped rivers, 17 of which are Special Areas of Conservation (SAC) for Atlantic salmon. See information on the map layer fields below.

Salmon Stock Assessment Areas boundaries were derived by Scottish Government Marine Scotland from Scottish Environment Protection Agency (SEPA) 1:50,000 river catchment boundaries, based on 1:50,000 DTM data from the Institute of Hydrology (now the Centre for Ecology and Hydrology). For SAC rivers, the outflow boundaries include information from Scottish Natural Heritage (SNH) (now NatureScot) and the Joint Nature Conservation Committee (JNCC).

Owners or masters of Scottish fishing vessels under 12m overall length must declare a latitude and longitude position (DD MM) on each fishing day indicating where the majority of the catch was taken.  This data has been recorded since 2016 for vessels submitting Fish 1 forms and from 2018 onwards for vessels submitting paper logbooks.

This dataset aggregates the positions declared between 2017 and 2021, along with the associated catch weight and values, into C-Squares of 0.05 x 0.05 decimal degrees. The data is grouped into sectors of 
"Pots and traps" - e.g. creels for crabs, lobsters, or Nephrops; whelk pots; or wrasse traps 
"Bottom trawls" - e.g. bottom trawls for Nephrops, squid, or demersal fish
"Dredges" - e.g. dredging for bivalve molluscs such as scallops and surf clams 
"Rod and lines"- e.g. handlines or jigging for mackerel; set lines for demersal fish
"Other" - e.g. set nets; diving; hand gathering etc

This data includes catches of razor clams up until 1st February 2018. Since this date, only vessels involved in the scientific trial can land razor clams.  Data will be published on these vessels once the trial is complete.
