“…In the current study, only 2 morphometric parameters (DFRL and P3) differ between populations. In contrast, several authors (Solomon et al, 2015;González et al, 2016) found significant differences between natural and domesticated fish populations. Besides, a few of the registered meristic characters (PcFR and RPcF) showed significant differences between populations, similar to the findings of Solomon et al (2015).…”

To better determine the ecological variation (body shape and structure) of the Vieja Azul (Andinoacara rivulatus; syn.: Aequidens rivulatus) in northwest Ecuador (Los Ríos Province), 300 specimens of both sexes (150 male and 150 female) were collected from 3 different locations, one from a wild production system and two from fish farm populations in the Quevedo River. Twelve meristic, 26 traditional morphometric, and 32 truss measurements, among 25 anatomical landmarks, were determined. The body weight (BW), total length (TL), eye diameter (ED), dorsal fin ray length (DFRL), and body perimeter 3 (P3) showed significant differences (P < 0.05) between production systems, and sex had significant influence on preanal length (Pre-AL), P3, and body width 2 (LC2). Females showed higher mean values than males in all measurements, except for BW. The Fulton factor differed for both factors considered. The canonical discriminant analysis revealed a percentage of correct assignment of 64.42% for the dataset, 85% and 60.9% for cultured and wild females, and 62.1% and 56.3% for wild and cultured males, respectively, as well as morphometric variation between groups. Results could be attributed to environmental conditions (habitat, temperature, and food). The Mahalanobis test showed greater distances among females than among males. In conclusion, this study provides valuable morphological information on the shape and structure of Andinoacara rivulatus that can be used to characterize and quantify the changes that occur as a consequence of adaptation to a different habitat. The authors hope that the information obtained from the present study will be helpful for fisheries, biologists, and taxonomists.

Materials and methods Ethical noteThe study was carried out according to the Ecuadorian national recommendations for fish management, with consideration for the rules on animal welfare. Study area and data samplingThis study was carried out in Los Ríos Province (Ecuador). The climate of the area is tropical with an average temperature of 25 °C, annual rainfall of 2400 mm, and relative humidity of 82%. Wild fish were caught from 3 separate locations within their natural geographic distributions in the Quevedo River (Los Ríos Province, Ecuador). Cultured fish were collected from 2 fish farms A total of 300 Andinoacara rivulatus individuals (150 wild and 150 cultured, of both sexes) were obtained at random from weekly catches made following the procedure described by Konings (1989) in 2017. All individuals were healthy adult fish. In the river, diurnal catches were made by native fishermen following the procedures described by Frost and Kipling (1980), Chávez-Lomelí et al. (1988), and Konings (1989. On the farms, fish were caught using standard fishing equipment. Farmed fish were fed 3 times per day, adjusting the consumption to 1.5% biomass. The diet composition was 32% crude protein, 7% fat, 5% crude ...

“…Although comparisons of the morphology between cultured and wild fishes from several species have already been carried out by several authors (Solomon et al, 2015;González et al, 2016), differences based on nutritional composition among cultured and wild C. festae stocks, have not been studied yet.…”

This study was conducted to determine the composition of cultured and wild Cichlasoma festae in Ecuador. The mean slaughter yield and dress-out were similar for cultured and wild specimens and the average fillet fat content for cultured fish was significantly higher compared to the wild fish. The pH, fillet color, drip loss and coked loss were similar between populations. Significant differences were found in protein, lipid and ash content in both studied populations. This study showed that saturated fatty acid (SFA) was higher than sum of monounsaturated (MUFA) and polyunsaturated fatty acid (PUFA) in both populations. Palmitic, oleic and linoleic acids had the maximum percentage of SFA, MUFA and PUFA respectively. In cultured and wild fish was also found to differ in the PUFA/SFA, docosahexaenoic acid/eicosapentaenoic acid, n-3/n-6 ratios and atherogenicity and thrombogenicity indices. Minerals included Ca, P, K, Mg, Zn, Fe, Cu and Mn. There were significant differences in the first six ones. The production system (cultured or wild) influences significantly most of the analyzed characteristics of carcass and flesh of C. festae. These results provide valued nutritional information of native species to produce sources of food with low-fat and high-protein, and safety food for the consumers in Ecuadorian country.

“…Los animales crecen de modo progresivo con diferencias significativas entre controles (p<0,05) y manteniendo en los pesos finales bajo error estándar y muy bajo coeficiente de variación. Con la tecnología Biofloc se obtuvieron crecimientos superiores a los reportados por Rodríguez et al (2017) (2) y González et al (2016) (14) para la misma especie en sistemas con recirculación de agua. Los pesos finales no se ajustaron a una distribución normal (p<0,05).…”

ReSuMenLa acuicultura favorece la soberanía alimentaria en Ecuador, mantiene sus medios de vida y potencia el incremento de los ingresos de la unidad familiar. La especie de agua dulce Cichlasoma festae representa una importante especie de gran uso local. En este estudio nuestro objetivo fue modelizar el crecimiento de alevines de Cichlasoma festae producidos en sistemas intensivos con tecnología Biofloc. El estudio duró 90 días y se llevó a cabo en la Finca experimental "La María", en la Universidad Técnica Estatal de Quevedo (UTEQ). Se situaron 15 jaulas dentro de un estanque circular de hormigón armado con Biofloc y se introdujeron 300 alevines de C. festae con un peso de 4,9 g. Quincenalmente, se midieron en 75 alevines de C. festae los parámetros biométricos individuales de longitud total, peso y altura. Diariamente se midieron los parámetros fisicoquímicos del agua de Biofloc (pH, temperatura, oxígeno, nitrógeno amoniacal total y sólidos en suspensión). El crecimiento se determinó utili zando modelos de regresión y en una segunda etapa se ajustó el peso al modelo seleccionado de mejor ajuste que fue: Log-Y Raíz Cuadrada-X que explica el 98,3% de la variabilidad en Peso.
