Abstract
Ispitivanja na koštunjačama iz uzgoja uvelike su pridonijela razumijevanju endokrinih osnova stresa kod riba; nasuprot tome, informacija o reakcijama na stres kod divljih riba i hrskavičnjača je vrlo malo. Analiza vremenskog tijeka aktivacije hipotalamusno-hipofizno-nadbubrežne osovine otkriva jaku neovisnost o temperaturi, pri čemu većina koštunjača prilikom stresa pokazuje vidljivi porast kortizola u plazmi unutar 10 minuta. Osim stresa, brojne druge varijable mogu utjecati na razine kortikosteroida, kao što su spol i zrelost, režim hranjenja te godišnje doba. Studije o pticama, koje žive slobodno, pokazuju da je stres u okolišu uglavnom uzrokovan nepredvidljivim promjenama, a oskudni podaci o ribama podupiru ovu teoriju. Postoji mogućnost korištenja reakcija na stres kao markera kvalitete okoliša, ali je najprije potrebno razumjeti osnove istih.
Abstract (english)
Studies of farmed teleost fish stocks have contributed much to understanding of the endocrine basis of stress in fish; in contrast, information on stress responses in wild fish and elasmobranchs is quite few. An analysis of the hypothalamic-pituitary-interrenal axis' time course of activation reveals a usually strong independence from temperature, with most teleosts exhibiting a detectable rise in plasma cortisol within 10 minutes of stress. In addition to stress, a number of other variables can affect corticosteroid levels, such as sex and maturity, feeding regime, and season. Studies on free-living birds indicate that environmental stress is mostly caused by unpredictable change, and the scant information on fish supports this theory. It is possible to use stress reactions as a marker of environmental quality, but only after thoroughly understanding the fundamentals of reactions to stress.
