“…In farmed rainbow trout, crude protein content was found significantly same in wild brown trout and crude lipid content was found the highest and significantly different in all groups (Antão-Geraldes et al, 2018). Barylo and Loboiko (2018) were found protein and lipid content higher in rainbow trout than brown trout in their study. But also inverse results can be seen in the literature, protein and lipid content were found lower in rainbow trout in the study of Cano-Estrada et al (2018).…”

Brown trout is a fish species that both is caught and is cultured. This study has presented a comparison on proximate composition, fatty acids profile and lipid quality of wild- and cultured brown trout, and Atlantic salmon. Crude protein and crude oil of Atlantic salmon were found highest than wild and cultured brown trout and significantly differences (P<0.05). Although there is no significantly difference (P<0.05) between cultured brown trout and Atlantic salmon on eicosapentaenoic acid (EPA), there are significantly differences (P<0.05) between three fish samples on linoleic acid, linolenic acid and docosahexaenoic acid (DHA) values. Cultured brown trout has given lowest oleic acid (C18:1n9c) value and ƩMUFAs (Mono unsaturated fatty acids) with 28.05% and 35.43%. Atherogenic index and thrombogenic index of all groups were found low values. Although the highest value h/H was found in Atlantic salmon, the highest value of FLQ (Flesh lipid quality) was found in cultured brown trout.

“…Необхідно зазначити, що зі зміною кліматичних умов та появою на ринку України нових штучних кормів провідних європейських виробників, які характеризуються збалансованим вмістом поживних речовин, виникла потреба в додаткових дослідженнях рибницько-біологічних особливостей американської палії, оскільки в умовах сьогодення вирощування гольців може становити потенційно новий сектор на ринку аквакультури завдяки її продуктивним, естетичним (екстер'єрним) та смаковим перевагам (Barylo, 2018, Barylo & Loboiko, 2018.…”

The article presents the research results on the growth dynamics of brook trout from caviar to commercial weight at different temperatures. Two groups of brook trout control and experimental individuals were formed to conduct the experiment, kept at different temperature regimes (control – natural water temperature, experimental – with partial heating at other times of the year up to 12 °С). The total duration of the embryonic period for brook trout, starting from fertilization of eggs and ending with free embryos at 2.8 °C was 101 days or 283 degrees-days; at 12 °C, incubation of eggs lasted 30 days (360 degrees-days). The yield of free trout embryos at a constant temperature was 90.5 % of the eggs laid for incubation. The yield of free embryos of brook trout, which was incubated at lower temperatures, was 82.9 %. The complete transition of brook trout larvae at a water temperature of 3.3 °C in the control group to artificial feed took place within 24 days of cultivation. In the experimental group, this transition lasted about ten days. The yield of larvae from embryos in control was 88.2 % in the experiment – 92.0 %. The larvae were then transplanted into 0.5 m3 plastic pools, where they were reared. Planting density in both cases was 5 thousand specimens/m2. The yield from rearing was almost the same and ranged from 91.4 to 92.5 %, but the average weight of young animals reared in heated water was significantly higher and was 3 g against 1.24 g in the control group. The duration of growing one-year-old trout was 240 days. The result was 3234 specimens of one-year-old in control weighing 15.57 g and 3603 specimens in the experiment weighing 35.5 g. The yield from cultivation was 77.0 and 85.8 %, respectively. Fish productivity was 2.5 times higher in the pool where the one-year-old research group was kept. The total weight of fish caught in the experimental group was 77.4 kg. One-year-old brook trout were planted in 30 m3 pools to produce marketable products. The average weight of fish of the control group at planting was 15.6 g, experimental – 35.5 g. 3000 specimens of one-year-old were planted in the pools. The duration of cultivation was 210 days. 2835 specimens were caught from the pools, the control pool, and 2874 specimens from the experimental one, with an average weight of 252.4 and 288.5 g, respectively. The total weight of fish caught was 1.2 times higher in fish of the experimental group. Fish productivity is 3.79 kg/m3 higher.

“…Встановлено, що такі види лососевих як американська палія, райдужна та струмкова форель вирощені у аквакультурі в умовах українських Карпат характеризуються високою харчовою цінністю за високим вмістом білків, мінералів та ліпідів (Barylo & Loboiko, 2018). Продуктивність видів та якість їх продукції в першу чергу залежить від генетичних факторів, які необхідно реалізовувати селекційними методами та створенням оптимальних умов вирощування (Mireșan et al, 2009).…”

This study aims to determine the reproductive indices of three types of salmon fish: brown trout (Salmo trutta morfa fario Linnaeus (1758), rainbow trout (Oncorhynchus mykiss Walbaum, 1792) and brook trout (Salvelinus fontinalis Mitchill, 1814) in aquaculture. For this purpose, 10 females and 10 males of each species were selected on an analogous basis and the main fishery-exteriors and reproductive characteristics were identified. The researching of relative fertility permit to establish that this indicator in brook trout females was 18.36% higher compared to rainbow trout, however, by 7.5% lower compared to the brown trout. It was found that brook trout eggs had less weight and size in comparison with other studied species. In particular, the weight and diameter of the eggs were 2.89 and 9.7% respectively lower than of rainbow trout, as well as 8.1 and 3.44% respectively lower compared to the brown trout. When studying the quantity of ejaculate, it was found that on average, brook trout males had 16.95% less of ejaculates compared to rainbow trout males, but 79.6% more than of brown trout males. When comparing the main indices of the brooders body of the studied species, it was found that the condition factor of the brook trout and rainbow trout females was quite high at 1.55–1.57, the brown trout one was 1.35, and the profile index respectively was 3.5, 3.52 and 4.0. The males' condition factor of brook trout, rainbow trout and brown trout was respectively 1.64, 1.52 and 1.35. Fishery-exteriors indicators met the requirements of brooders species and age specificity norms of the studied fish species.
