“…Fish for human consumption are acquired from two main sources. One is the intensive breeding combined with artificial reproduction in captivity [ 10 , 11 , 12 , 13 , 14 ] and the other is fishing in oceans, seas, lakes and rivers. Fish farming, especially in recirculated aquaculture systems (RAS), is carried out under strict control of both the physicochemical parameters of water and food quality (e.g., [ 15 , 16 ]).…”

The aim of this study was to determine the mercury content and fatty acids profile in roach (Rutilus rutilus L.) and European perch (Perca fluviatilis L.) from Lake Łańskie (Poland). Mercury content was higher in the muscles than other organs in both species (p < 0.05). Mercury accumulates along the food chain of the lake’s ecosystem. The value of the bioconcentration factor (BCF) indicated that Hg had accumulated in the highest amounts in muscles and in the other organs as follows: muscles > liver > gills > gonads. The metal pollution index (MPI) and target hazard quotient (THQ) were below 1, which means that these fish are safe for consumers. The values of HIS, GSI and FCF indicators show that both species of fish can be good indicators of water quality and food contamination. There were few differences between fatty acid content in the muscles of perch and roach. Contents of fatty acids having an undesirable dietary effect in humans (OFA—hypercholesterolemic fatty acids) were lower compared to hypocholesterolemic fatty acids (DFA, i.e., the desirable ones). In addition, the lipid quality indices AI and TI in the muscles of fish were at 0.40 and 0.22 (perch) and at 0.35 and 0.22 (roach), respectively. On this basis, it can be concluded that the flesh of the fish studied is beneficial from the health point of view.

“…This agent’s effectiveness in out-of-season reproduction of rheophilic cyprinids is very low. Moreover, the application procedure requires two to four injections, which is stressful for the fish and may result in their increased mortality [ 54 , 55 ]. According to Syndel, the Ovaprim manufacturer, the product shortens and synchronizes spawning, reduces fish stress, increases egg production, extends its activity and improves spawning effectiveness.…”

The blue bream Ballerus ballerus (L.) is one of two species of the Ballerus genus occurring in Europe. The biotechnology for its reproduction under controlled conditions needs to be developed to conserve its local populations. Therefore, a range of experiments were performed to obtain valuable gametes from blue bream following hormonal stimulation with carp pituitary homogenate (CPH), Ovopel and Ovaprim. CPH and Ovopel were injected twice and Ovaprim—once, under a pectoral fin. The spawners were inspected 12 h after the last injection, and the gametes were collected. Eggs were collected from spawning females and fertilized with sperm from three males. The smallest number of ovulating blue bream (four females) was obtained from individuals stimulated with Ovaprim. There were six to nine ovulating females in the other groups, accounting for 60–90% of the females in the respective groups. The latency period was the shortest in the spawners stimulated with Ovopel. The fish in this group ovulated 14 h after the hormonal injection. Spawning was synchronized and all females spawned simultaneously. The highest average weight of eggs per fish (75.4 g) was obtained from the females stimulated with Ovopel, whereas the individuals stimulated with Ovaprim provided the smallest average amount of eggs (49.5 g). The study showed that blue bream spawners are not very sensitive to reproduction-related handling under controlled conditions.

“…Se reporta que existe un posible asincronismo entre los picos de madurez de hembras y machos a lo largo del año (Lenis et al, 2015). En los sistemas de producción piscícola no ha sido todavía posible romper la estacionalidad del ciclo reproductivo (Cruz-Casallas et al, 2006), siendo por esta razón, que se utilizan hormonas para inducir la madurez y la ovulación, las cuales no son suficientes si no van acompañadas de condiciones ambientales específicas, tales como la temperatura y el fotoperiodo (Kucharczyk et al, 2005(Kucharczyk et al, , 2017.…”

“…Se conoce que la maduración de los gametos de los peces puede requerir, según la especie, de la estimulación mediante condiciones ambientales como temperatura y salinidad del agua, del uso de estimulación hormonal o de la combinación de ambos (Muller et al, 2005;Kucharczyk et al, 2017). Se han utilizado preparados hormonales con extracto de hipófisis de carpa (EPC) y análogos de GnRH como la hormona liberadora de gonadotropinas de salmón (sGnRHa), combinados con inhibidores o antagonistas de la dopamina (Ovopel, Ovaprim, OvaRH), los cuales actúan como bloqueadores de los factores inhibidores de la liberación de gonadotropinas (GRIF) (Peter et al, 1988), influencian directamente las gónadas y causan la maduración de los oocitos (Kucharczyk et al, 1997, Brzuska, 2006Jamróz et al, 2008).…”

La sabaleta (Brycon henni) es una especie de interés comercial en Colombia. Una de las principales barreras para los procesos de conservación de esta especie es la asincronía temporal entre los ciclos reproductivos de las hembras y los machos, que podría ser solucionado mediante el uso de procesos biotecnológicos. El objetivo de esta investigación fue evaluar la maduración in vitro de ovas de sabaleta (Brycon henni) mediante el uso de dos preparaciones hormonales. Un total de 1200 ovas fueron sometidas a maduración in vitro en presencia de extracto de hipófisis de carpa (EPC), hormona liberadora de gonadotropinas de salmón (sGnRHa) y un control sin estimulación hormonal. Las ovas se incubaron durante 2 horas a 25 °C en agitación orbital constante y 80% de O2. Se evaluó la maduración in vitro de las ovas mediante la clasificación de la posición del núcleo en cuatro categorías: migratorio, central, atrésico y periférico. Se encontraron resultados superiores de avance de la maduración por la presencia de núcleo migratorio (p<0.05) para EPC (46.0 ± 8.4%) y sGnRHa (40.0 ± 13.3%), en comparación con el control (24.0 ± 9.6%). Se concluye que el uso de las preparaciones hormonales EPC y sGnRHa durante la maduración in vitro promueve el avance de la maduración de las ovas de sabaleta (Brycon henni).
