Polskie przepisy zakazujące wpuszczania tęczaków do wód otwartych, to pomysł "chorych" ludzi. "Cały świat" zarybia pstrągiem tączowym, a z nas się śmieją - cóż polska rzeczywistość. .
Jeśli Wielka Brytania z prawie milionem muszkarzy jest istotnym kawałkiem tego "całego świata", to do pstrągów tęczowych w wodachotwartych nastawienie ma nastepujące:
Policy 19: Rainbow trout into rivers, streams and
other unenclosed waters
• Subject to other constraints, we will permit
introductions where there is a history of stocking
to sustain a fishery or where the introduction of
non-breeding rainbow trout can be clearly
demonstrated to be a preferred environmental
option.
• In all other cases, we will not consent the
introduction of rainbow trout into rivers, streams
or other unenclosed waters.
Ponadto, w aktualizacji National Trout and Grayling Fisheries Strategy zaplanowano odstąpienie do 2015 roku zupełnie od zarybiania hodowlanymi, diplidalnymi, płodnymi pstrągami potokowymi, na rzecz wprowadzania triploidalnych, niepłodnych. Zarybienia dokonywanego oczywiście rybami o masie ok. 0,5 kg (1 lb - 1 1/4 lb) do ok 1 kg (2 lb and above).
Brown trout stocking into all but totally enclosed waters with no significant
natural brown trout production will be with non-fertile, all female triploid brown
trout or from breeding programmes using local wild-sourced broodstock.
This policy will be fully implemented by 2015, and from then we will no longer
consent the stocking of farm strain diploid brown trout to rivers. Until 2015 we
hope to see a voluntary progressive switch to the stocking of female triploid
trout.
Putting the Policy into Practice
We are phasing in the Policy to give anglers, fisheries and fish farms time to adapt.
By: 2010 – we would like to see 30% fewer farm-strain brown trout stocked into rivers.
2013 – we would like to see 50% fewer.
2015 – we will cease to allow farm strain fertile brown trout to be stocked into rivers.
