\"\"V \u0159ece Kamenici u\u017e zase \u017eij\u00ed lososi. Kdy\u017e jsem to nad\u0161en\u011b vykl\u00e1dal ostatn\u00edm z party, zaujalo to jenom Hardyho. Prohl\u00e1sil, \u017ee takov\u00fd losos na grilu je vylo\u017een\u011b pochoutka. Nev\u00edm.

 <\/p>\n

Alfa s Betou mou radost okomentovaly slovy, \u017ee jsem \u00fapln\u011b mimo, proto\u017ee losos je p\u0159ece mo\u0159sk\u00e1 ryba. No, je i nen\u00ed. Lososi to s \u017eivotem v sladk\u00e9 \u010di slan\u00e9 vod\u011b maj\u00ed tak nap\u016fl. Podobn\u011b jako t\u0159eba \u00faho\u0159i.<\/p>\n

 <\/p>\n

\"\"Je to vlastn\u011b neuv\u011b\u0159iteln\u00e9. Evrop\u0161t\u00ed \u00faho\u0159i \u0159\u00ed\u010dn\u00ed z\u0159ejm\u011b putuj\u00ed z \u0159ek do Sargasov\u00e9ho mo\u0159e, to se nach\u00e1z\u00ed v Atlantsk\u00e9m oce\u00e1nu, v\u00fdchodn\u011b od Floridy. Uplavat v mo\u0159i 7000 kilometr\u016f jim trv\u00e1 rok a p\u016fl. V Sargasov\u00e9m mo\u0159i se t\u0159ou a pl\u016fdek je pak Golfsk\u00fdm proudem zanesen k pob\u0159e\u017e\u00ed Evropy. \u00dast\u00edm \u0159ek se mlad\u00ed \u00faho\u0159i dost\u00e1vaj\u00ed do sladk\u00e9 vody. Tato cesta jim trv\u00e1 3\u20134 roky. Kdy\u017e dosp\u011bj\u00ed, vyd\u00e1vaj\u00ed se op\u011bt na mo\u0159e, kde zplod\u00ed potomky, ale do \u0159eky u\u017e se nevracej\u00ed.<\/p>\n

 <\/p>\n

A s lososy je to n\u011bco podobn\u00e9ho, jen obr\u00e1cen\u011b. \u00daho\u0159i kv\u016fli rozmno\u017eov\u00e1n\u00ed plavou z \u0159ek do mo\u0159e, kde nakladou jikry, lososi naopak opou\u0161t\u011bj\u00ed mo\u0159e a pluj\u00ed nakl\u00e1st pl\u016fdek do horn\u00edch tok\u016f \u0159ek.<\/p>\n

 <\/p>\n

Lososi v\u011bt\u0161inu \u017eivota \u017eij\u00ed v mo\u0159i. Dosp\u011bl\u00ed jedinci v\u0161ak pluj\u00ed do rodn\u00e9 \u0159eky, kterou pravd\u011bpodobn\u011b najdou podle typick\u00e9ho slo\u017een\u00ed vody, a na horn\u00edm toku se t\u0159ou. Z oplodn\u011bn\u00fdch jiker se vyl\u00edhnou mal\u00ed lososi, kte\u0159\u00ed v \u0159ece \u010di byst\u0159in\u011b \u017eij\u00ed jeden a\u017e dva roky. Kdy\u017e dosp\u011bj\u00ed, vyd\u00e1vaj\u00ed se na mo\u0159e. V Atlantsk\u00e9m oce\u00e1nu str\u00e1v\u00ed p\u0159ibli\u017en\u011b dva roky a pak se vracej\u00ed do rodn\u00fdch \u0159ek, aby dali vznik dal\u0161\u00ed generaci.<\/p>\n

 <\/p>\n

\"\"Fungovalo to takhle oded\u00e1vna. Jen\u017ee pak p\u0159i\u0161el \u010dlov\u011bk a postavil na \u0159ek\u00e1ch p\u0159ehrady, jezy a zdymadla, \u010d\u00edm\u017e losos\u016fm putov\u00e1n\u00ed \u0159ekou znemo\u017enil. Na \u00fazem\u00ed \u010cesk\u00e9 republiky byl losos ve 20. stolet\u00ed \u00fapln\u011b vyhuben.<\/p>\n

Dnes u\u017e se na vodn\u00edch d\u00edlech buduj\u00ed ryb\u00ed p\u0159echody, kter\u00fdmi mohou lososi, \u00faho\u0159i a dal\u0161\u00ed ryby proplout.<\/p>\n

Jeden takov\u00fd losos\u00ed p\u0159echod je postaven\u00fd i na doln\u00edm p\u0159\u00edstavi\u0161ti Edmundovy sout\u011bsky, proto\u017ee Kamenice je \u0159eka, kde se lososi op\u011bt uchytili. \u010cesk\u00fd ryb\u00e1\u0159sk\u00fd svaz je sem um\u011ble vysadil v roce 1998. A v roce 2002 se tahle prvn\u00ed generace vr\u00e1tila z Atlantiku dom\u016f.
