The first No Take Zone in Scotland is at the north end of Lamlash Bay and was established in September 2008. The NTZ is a 2.6Km2 area of sea and seabed from which no marine life can be removed by any fishing method, whether it is recreational or commercial. Interpretation boards showing the variety of marine life in the bay are situated along Shore Road towards Claucland's Point. The NTZ is playing an important role in the protection and recovery of marine habitats, helping to protect and regenerate marine biodiversity.
In a 2011 study by researchers at the University of York and published in the journal Marine Biology, found the number of scallops within the Lamlash No Take Zone to be ten times higher than in surrounding waters. Dr Bryce Beukers-Stewart, of the University of York, described the findings as a "win win scenario" and said: "Marine reserves like this can benefit both fishermen and conservationists." The number of juveniles in the entire zone had to be estimated on the basis of sample counts. There were, he said, "too many to count" individually.

There is some evidence that salmon farming in the no take zone may be impacting the seafloor, though industry representatives deny this. Salmon farms in the zone have also been linked to the outbreak of Amoebic Gill Disease. Local envrionmental groups are skeptical of industry claims of no negative impact.
Scotland’s first No Take Zone (NTZ) was designated by the Scottish Government on 20 September 2008 at the north end of Lamlash Bay on the east of the Isle of Arran. It was established to protect
beds and to promote natural regeneration of all marine life. It covers an area of 2.67sq km of sea and seabed from which no marine life can be removed by any method. This was achieved after over a decade of campaigning by the island community.
is a very slow-growing (1mm per year) coral-like calcareous red algae and is an important Scottish species. Maerl beds are reservoirs of biodiversity, important both as nursery grounds for young scallops and young fish. Studies show that organic waste from fish farms significantly reduces live maerl and that scallop dredging has profound and long lasting impacts. Scallop dredging on a maerl bed has been found to kill over 70% of live maerl, with no discernible recovery over the following four years. Recovery of maerl beds would be expected to require many years without disturbance.
No take zones are likely to economically benefit fisheries and tourism sectors and have done so in many areas of the world.
By protecting a certain area from external disturbances such as damaging fisheries, biomass and diversity can flourish and improve within a short time. Nearby fisheries and ecosystem can benefit from an enhanced recruitment within the protected area when individuals leave the protected zone (
). Long term, the establishment of a network of protected zones can create optimal harvesting areas.
An example for the beneficial effects of a protected marine area is the UK’s first NTZ around
, where, 5 years after its creation, professional surveys of the ecological effects have found an increase in abundance and average size of landable-sized lobsters, both within and adjacent to the protected area. Next to the lobster-fishers, also the local tourism sector recorded an increase of divers, anglers and sightseers thanks to the increased publicity surrounding Lundy and the marine reserve as a result of its designation.
