多年来，马里湾一直是密集捕捞的海域，对苏格兰渔业的发展具有重要的历史意义。描述了在峡湾开发的物种的股票和它们的关系，在苏格兰沃茨的其他股票。被开发的底层鱼种包括黑线鳕、鳕鱼、鳕鱼、欧鲽和柠檬鳎。河口是一个重要的鱼苗场，是北海最重要的鲽产卵场。马里湾也是鲱鱼的重要育苗区。有证据表明，这些鱼招募成年股票在明奇。在1960年代早期，一种对拖网渔业开始捕捞鲱鱼，而弗斯成为苏格兰最重要的鲱鱼捕捞区。然而，近年来的捕捞量太少，无法维持渔业，渔业现已关闭，以保护作为副渔获物上岸的幼鱼。贝类的分布与底质密切相关。随着底层和中上层渔业的减少或进一步离岸，上岸变得越来越重要。挪威龙虾的渔业现在特别重要，单位努力量渔获量数据并不表明种群规模有任何下降。其他被开发的物种包括鱿鱼、扇贝、螃蟹和龙虾。
The Moray Firth has been intensively fished for many years and has been of great historic importance to the development of Scottish fisheries. The stocks of exploited species in the firth and their relations to other stocks in Scottish waters are described. Exploited demersal species include haddock, cod, whiting, plaice and lemon sole. The firth is an important nursery area for plaice, and is the most important plaice spawning ground in the North Sea. The Moray Firth is also an important nursery area for herring. Evidence suggests that these fish recruit to adult stocks in the Minch. In the early 1960s a pair trawl fishery for sprats started and the firth became the most important sprat fishing area in Scotland. However, recruitment of recent year classes has been too poor to sustain the fishery, which has now been closed in order to protect the juvenile heiring which were landed as by-catch. The distributions of shellfish species are closely related to the bottom sediments. Landings have become increasingly important as the demersal and pelagic fisheries have declined or moved further offshore. The fishery on the Norway lobster is now of particular importance and the catch per unit effort data do not suggest any decline in stock size. Other exploited species include squid, scallops, crabs and lobster.
