O Alburnus tarichi representa cerca de 30% da captura anual em águas interiores na Turquia, que é de cerca de 33 mil toneladas. O lago Van é o maior lago alcalino do mundo e o maior lago da Turquia, com 3.602 km2. Devido à indisponibilidade de dados pormenorizados para os modelos ricos em dados, a unidade populacional de A. tarichi foi avaliada pelo modelo de rendimento máximo sustentável baseado nas capturas (CMSY), com base nos dados de captura dos anos 1967 a 2021. Os valores e os seus intervalos de confiança foram calculados para a unidade populacional do lago Van tarek pelo modelo CMSY e são apresentados do seguinte modo MSY = 12,3 (10,8-14,2) ton*1.000, k = 92,4 (66,5-129) ton*1.000, r = 0,536 (0,377-0,76)*ano-1, B2021 = 48,0 (29,4-55,1) ton*1.000, BMSY = 46,2 (33,2-64,3) ton*1,000, F2021 = 0,202 (0,180-0,338)*ano-1, FMSY = 0,268 (0,189-0,380)*ano-1, F2021/FMSY = 0,772 (0,672-1,260), e B2021/BMSY = 1,04 (0,636-1,190). Este estudo revelou que a unidade populacional de A. tarichi foi sujeita a uma pressão de pesca significativa e continuamente crescente desde os primeiros anos de inexploração (1967-1996) e acabou por ser objeto de sobrepesca nos anos seguintes (1997-2010). Após a proibição da pesca estival em 1997, que reduziu significativamente o recrutamento, a unidade populacional começou a entrar num período de recuperação no início da década de 2000. Consequentemente, a unidade populacional de A. tarichi atingiu atualmente um nível sustentável e foi avaliada como uma unidade populacional saudável com base nos resultados do CMSY.
