Rainbow Trout in the UK
Introduction:
Rainbow trout were introduced to the UK from the US in the early 1900s, coinciding with the expansion of water supplies for growing industrial cities like Bristol and Birmingham.
Success in Adaptation:
Despite their inability to breed naturally in most British rivers, rainbow trout have thrived due to their voracious appetite and habit of forming schools. These traits, along with a faster growth rate than native brown trout, quickly made them popular with both fishermen and fish farmers.
Challenges and Solutions:
Initially, two strains?"Kamloops and Shasta?"were used, leading to challenges as they matured at different times, resulting in discolored catches. However, the development of egg treatment techniques led to Diploid rainbow trout, which are sterile females. These fish are available year-round and grow faster, providing cleaner catches and improving angling experiences.
Impact on Fishing Seasons:
The introduction of sterile rainbow trout also enabled the abolition of the closed fishing season, thanks to pressure from fishery owners and anglers. This change benefited fisheries significantly, prompting a competition to grow and stock larger trout, leading to record-breaking catches.
Selective Breeding and Growth:
Selective breeding and intensive feeding programs have further accelerated growth rates, resulting in today's "Jumbo" rainbows. This has complicated record-keeping, with separate listings for recently stocked, longer-term stocked, and wild trout.
Current Records:
As a result of these efforts, the current British record for rainbow trout stands at an impressive 33 lbs. 4 oz.
In summary, the introduction and subsequent development of rainbow trout in the UK have revolutionized recreational fishing, offering year-round opportunities and fostering substantial growth in the angling and aquaculture industries.
