Abstract
Cilj istraživanja bio je odrediti dužinsko-maseni odnos i udio masnih kiselina u mišićnom tkivu hame (Argyrosomus regius) pri različitoj hranidbi. Pokus je proveden u tri hranidbena tretmana: CF (SP=48,0; SM=16,0) EXF (SP=52,0; SM=21,0) NCF (SP=56,0; SM=18,0) s dva ponavljanja (3x2) u morskim akvakulturnim kavezima dimenzija 9x5x5 m (V=225 m³) na lokaciji otoka Bisage (44°01´28.6"N 15°13´11.2"E) tijekom 17 mjeseci. Najveći postotak lipida (16,81%) u mišićnom tkivu zabilježen je kod EXF hranidbene smjese. Također, u istoj skupini utvrđen je najviši udio ukupnih ω-3 masnih kiselina (35,46 ± 6,12) dok je prosječni omjer ω3:ω6 masnih kiselina iznosio 3,86±1,54. Ribe hranjene EXF smjesom, imale su više vrijednosti završne mase i dužine tijela u odnosu na ribe hranjene CF i NCF. Jedinke CF hranidbene skupine imaju pozitivan alometrijski rast, (b=3,186) s vrijednostima kondicijskog faktora 1,27, tj napredovale su više u masu. Jedinke NCF i EXF hranidbenih skupina imaju negativan alometrijski rast,(NCF b=2.037, CF=1.19; EXF b=2.953, CF=1.22) što nam ukazuje da su jedinke riba napredovale više u dužinu nego u masu. Istraživanje indicira EXF kao hranidbenu smjesu povoljnog kemijskog sastava pri čijoj konzumaciji riba postiže pogodan masnokiselinski profil te više vrijednosti završne mase i dužine.
Abstract (english)
The aim of this study was to evaluate the lenght – weight relationship and fatty acid profile of muscle tissue of meagre (Argyirosomus regius) fed with different feed mixtures. The experiment was performed in the form of three feeding groups CF (CP=48,0; CF =16,0), EXF (CP=52,0; CF =21,0), NCF (CP=56,0; CF=18,0) with two repetitions (3x2) in marine aquaculture cages of 9x5x5 m (V = 225 m³) at the location of the island of Bisage (44° 01'28.6 "N 15° 13'11.2" E) during 17 months. Fish were fed to satiety. The highest percentage of lipids (16.81%) in muscle tissue was recorded in the EXF feed. Also, in the same group, the highest average proportion of total ω-3 fatty acids (35.46 ± 6,12) was found. The ω3/ω6 fatty acids ratio was highest in EXF (3,86 ± 1,54). Fish fed with EXF had higher final weight and total length compared with CF and NCF. CF feeding group had a positive alometric growth, (b = 3.186) with condition factor (CF) of 1.27. NCF and EXF feeding groups have a negative alometric growth, b <3 (NCF b=2.037, CF=1.19; EXF b=2.953, CF=1.22), which indicates that the fish progressed more in length than in mass. The study indicated EXF as a nutritional mixture of favorable chemical composition and by consumption fish achieves a suitable fatty acids profile and high nutritive quality.
