Declarations
:
: This article does not contain any studies with human participants performed or experiments conducted on animals by any of the authors. All care and use of animals were complied with animal welfare international/national laws, guidelines, and policies. The collection of round goby individuals did not require special approval from an Ethical Committee in all the countries sampled, including Türkiye, Croatia, Slovakia, Poland, and Finland. In each country, the capture of fish was conducted in accordance with national regulations, which, in the cases of Türkiye, Croatia, and Poland, necessitated additional tenancy agreements (E-67852565–140.03.03–5071302, UP/I-324–01/22–01/5, and PGR-W/Z/704/2022, respectively). The euthanasia procedure involved the use of spinal cord rupture, a method chosen to ensure the humane treatment of animals and to prevent unnecessary suffering in accordance with ARRIVE guidelines.
