This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.[EN] The apparent digestibility coefficients (ADCs) of dry matter, crude protein, crude lipid, and amino acids in fish, krill, squid, meat, defatted krill, soybean, wheat gluten, wheat, camilina, pea, sunflower, and fava bean meals were determined for juvenile Seriola dumerili. The results showed that the ADC of dry matter for yellowtail ranged from 57.7 to 87.2% for animal ingredients and from 42.2 to 82.2% for plant ingredients. An ADC of protein exceeding 90% was observed in fishmeal, while camilina meal and fava bean meal presented the lowest values. Pea meal presented the lowest lipid ADC (83.5%). The availabilities were generally higher in animal ingredients than those in vegetal ones. Except camilina and fava bean meal, the other ingredients appear to be favorable for S. dumerili diets, especially the ones from animal sources. Lower case chemical score values (minimum value from amino acid ratios [AARs]) were obtained in some vegetal ingredients (14¿18%), while the highest ones were observed in marine ingredients (69¿88%). According to Oser's Index, the most balanced protein for yellowtail with regard to essential amino acids was in krill, defatted krill, and fishmeal (92¿96%). So, animal sources are suitable as protein ingredients, but they could be enhanced through some essential amino acid supplementation.This project was financed by the “Ministerio de Ciencia e Innovación” (reference AGL2011-30547-C03).Tomas-Vidal, A.; Monge-Ortiz, R.; Jover Cerda, M.; Martínez-Llorens, S.

Nutritional value of four pest animals to be used in feeding monogastric organisms

[ES] Las muestras de animales plagas fueron colectadas, secadas y molidas. Estas fueron analizadas para determinar su contenido en proteína, cenizas y aminoácidos. Los análisis bromatológicos mostraron que Achatina fulica y Pieris brassica, contienen más proteína bruta, (PB) (779.2 y 812.2 g/kg) en comparación a Phyllophaga spp. y Spodoptera frugierda (432. 5 y 445.7 g/ kg). Comparando el perfil de aminoácidos, A. fulica y P. brassica obtuvieron los niveles más altos en la mayoría de los amino ácidos esenciales (AAE) que la torta de soya y en el caso de A. fulica, éste exhibió valores más altos que la harina de pescado en arginina, cisteina, glicina, serina y tirosina. Observando la relación de AAE/AANE (amino ácidos no esenciales) en las harinas, sólo S. frugiperda presentó valores similares a la harina de pescado (0.85). Todas las harinas de animales plagas presentaron una reducción en la cuantificación de amino ácidos en relación con los valores de PB obtenidos por el método de Kjeldahl, esta reducción se encontraba entre 28.6 y 38.0%. Esta disminución podría deberse a la combinación entre la proteína y la quitina que se encuentran en el cuerpo de los insectos. A pesar de esta reducción la cuantificación de amino ácidos de los animales plagas podría ser una buena alternativa para su uso en la alimentación de monogástricos, especialmente para peces y crustáceos.[EN] The pest samples were collected, dried, and grounded. They were analysed to determinate contain of protein, energy, ashes and amino acids. The bromatological analysis showed that Achatina fulica and Pieris brassica, obtained a higher amount of crude protein (CP) (779.2 and 812.2 g/kg) in comparison to Phyllophaga spp. and Spodoptera frugiperda (432.5 and 455.7 g/kg). Comparing the amino acids profile, A. fulica and P. brassica obtained higher values in most of the essential amino acids (EAA) than soybean meal, and A. fulica exhibited even higher values than fish meal (FM) in Arginine, Cysteine, Glycine, Serine, and Tyrosine. Observing the relation of EAA/NEEA (no essential amino acids) in all the meals only S. frugiperda presented a similar value to fish meal (0.85). All the pest meals presented a reduction in the amino acids quantification in comparison to the CP values obtained by the Kjeldahl method, with reduction between 28.6 through 38.0%. This diminution could be due to the linkage of the protein to the chitin content of the insect body. In spite of the reduction of the amino acids quantification, the pest meals could be an alternative in feeding monogastric organisms, especially fish and crustaceans.To the Polytechnic University of Valencia for it support.Nogales Mérida, S.; Velazco Vargas, JL.; Martínez-Llorens, S.; Tomas-Vidal, A.

Evaluation of soybean meal as protein source for Argyrosomus Regius (Asso, 1801) (Sciaenidae)

[EN] The meagre (Argyrosomus regius) is a carnivorous fish which requires diets with higher protein content, causing an increment in diets cost. A way to diminish this cost is to use vegetable meals like soybean meal (SB). So the aim of this trial was to determine the optimum inclusion level of defatted soybean meal in experimental diets for this species. 800 fishes (165 g) were distributed in 8 tanks, two replicates per treatment. Four isoproteic (50% CP) and isolipidic (17% Cl) diets were formulated with four levels of soybean meal inclusion, 0, 15, 30 and 45%. The trial lasted 107 days. Meagre fed diets 15 and 30% obtained the highest final weight. There were no significant differences among treatments in the feed conversion rate (FCR) and the protein efficiency (PER). According to the quadratic regression, the optimum SB inclusion to maximize thermal growth coefficient (TGC) was 26.4% and for FCR was 27.6%. No significant differences were observed in energy, protein and amino acid retention among diets. The inclusion of SB in meagre diets can generate a decrease in the use of fish meal and in turn reduce the cost of producing meagre Mediterranean aquaculture industry.Velazco Vargas, JL.; Martínez-Llorens, S.; Jover Cerda, M.; Tomas-Vidal, A.

Successful inclusion of high vegetable protein sources in feed for rainbow trout without decrement in intestinal health

[EN] A reduction in fishmeal in diets is essential to achieve the aim of sustainable production. In the current work, using a plant protein blend of wheat gluten, wheat and soybean meal supplemented with Tau, Val, Lys and Met, a 10% higher fishmeal substitution without affecting growth and health parameters has been accomplished. The aquaculture of carnivorous fish is in continuous expansion, which leads to the need to reduce the dependence on fishmeal (FM). Plant proteins (PP) represent a suitable protein alternative to FM and are increasingly used in fish feed. However, PP may lead to stunted growth and enteritis. In the current study, the effect of high FM substitution by PP sources on the growth, mortality and intestinal health of rainbow trout (Oncorhynchus mykiss) was evaluated in terms of the histological intestine parameters and expression of genes related to inflammation (IL-1 beta, IL-8 and TGF-beta) and immune responses (Transferrin, IgT and IFN-gamma). The results show that a total substitution registered lower growth and survival rates, probably due to a disruption to the animal's health. Confirming this hypothesis, fish fed FM0 showed histological changes in the intestine and gene changes related to inflammatory responses, which in the long-term could have triggered an immunosuppression. The FM10 diet presented not only a similar expression to FM20 (control diet), but also similar growth and survival. Therefore, 90% of FM substitution was demonstrated as being feasible in this species using a PP blend of wheat gluten (WG) and soybean meal (SBM) as a protein source.Vélez-Calabria, G.; Peñaranda, D.; Jover Cerda, M.; Martínez-Llorens, S.; Tomas-Vidal, A.

Enhancement of quality of rainbow trout (Oncorhynchus mykiss) flesh incorporating barley on diet without negative effect on rearing parameters

[EN] Barley concentrations ranging from 0 to 32% (0B, 40B, 80B, 160B, and 319B) were incorporated into rainbow trout, Oncorhynchus mykiss (Walbaum) diets. The experiment started with an initial average fish weight of 127.72 +/- 5.65 g and finished when they reached commercial weight (final weight between 312 and 330 g) after 84 days. The inclusion of barley in the diets did not show a significant effect on growth and biometric parameters, fat and carbohydrate digestibilities; however, protein digestibility decreased significantly with the incorporation of barley on diets. Glucose levels increased significantly with barley concentration in the diet, and lactate and cortisol levels were also significantly affected after a stress period regardless of the diet. Meat quality was influenced as well by barley concentration. Lower water activity values and an enhancement in textural and color properties were observed in fish fed with the diet containing the highest barley concentration. Trout fed feed with higher concentrations of barley (160B) showed lower lipid oxidation levels than those fed with lower concentrations (control and 40B). The sensory panel found that fish fed with diets higher than 8% in barley content (80B) exhibited a brighter red color in the gills and a better texture; also, meat color became redder with a higher barley inclusion (160B and 319B), being all these sensory parameters correlated with fish freshness. Thus, results indicate that barley can be substituted for wheat fraction without any detrimental effect on production efficiency and enhancing fish quality.This work has been co-funded with FEDER and INIA funds.

Protein and energy requirements for maintenance and growth in juvenile meagre Argyrosomus regius (Asso,1801) (Sciaenidae)

[EN] The meagre is a fish species of recent interest in aquaculture, because of its fast growth and flesh quality. Nevertheless, it hasn't been studied enough, and feed producers do not have enough information about the nutrient requirements to optimize the feed diets of the meagre. This study measures the growth response of this fish to several amounts of food and gives information about the proportion of protein and energy that should be included in its diet, as well as the recommended amount of food to optimize its growth. The meagre is a carnivorous species and might be a suitable candidate species for the diversification of aquaculture in the Mediterranean region. This is based on its high growth and flesh quality. Nevertheless, there is little information available about its growth rates and nutrient requirements. The objective of this study was to determine the protein and energy requirements of juvenile meagre (Argyrosomus regius). Two trials for different weights of 53 and 188 g were conducted with rations from starvation to apparent satiation with the scope of studying its nutritional needs. In the first trial, the initial mean body weight of the fish was 53 g, and they were fed at feeding rates, measured as a percentage of the body weight, of 0, 0.75, 1.5, 2.5, 3.5, and 4.5%, with two replicates per treatment. In a second trial, another group with approximately 188 g of initial body weight was fed at feeding rates of 0, 0.5, 1.5, and 2.5%, with two replicates per treatment. The optimum thermal growth coefficient was obtained with a feed intake of 2.2% day(-1) in trial A and 1.73% day(-1) in trial B. The digestible protein (DP) intake for maintenance was determined as 0.57 g kg(-0.7) day(-1), the DP intake for maximum growth was 6.0 g kg(-0.7) day(-1), and the point for maximum efficiency in protein retention was 1.8 g kg(-0.7) day(-1). The requirement for digestible energy (DE) intake for maintenance was recorded at 25.4 kJ kg(-0.82) day(-1), the DE intake to maximize growth was 365 kJ kg(-0.82) day(-1), and the point for maximum efficiency in energy retention occurs with a digestible energy intake of 93 kJ kg(-0.82) day(-1). The requirements and retention efficiency of protein and energy in Argyrosomus regius tend to be within the range other fish species. The maintenance needs are in agreement with species with low voluntary activity and growth requirements in agreement with fast-growth species.This research was funded by grants from the Planes Nacionales de Acuicultura (JACUMAR) in Spain.Jauralde García, I.; Velazco-Vargas, J.; Tomas-Vidal, A.; Jover Cerda, M.; Martínez-Llorens, S.

Effects of Eco-Organic Feed on Growth Performance, Biometric Indices, and Nutrient Retention of Gilthead Seabream (Sparus aurata)

[EN] This study examined how eco-organic feed affects the growth performance, nutrient efficiency, feed utilisation, and body composition of gilthead seabream. Six different diets were tested, including a control diet (CONT) without organic ingredients and four diets with 100% organic ingredients: trout (TRO), seabass (SBS), poultry (POU), and mix (MIX), along with a control organic diet (ORG) containing organic ingredients and 30% fishmeal. The experiment lasted 70 days, and the fish were fed twice a day, starting with an initial weight of 60.5 g. The results showed that the highest growth rates were observed in fish fed the ORG and CONT diets containing fishmeal. Conversely, the POU diet resulted in the lowest growth rate, survival rate, and highest value for feed conversion ratio (FCR). Almost all essential amino acid efficiency values were high in fish fed the ORG and CONT diets. Still, significant differences were noted in the retention efficiency of fatty acids across all diets. The retention efficiency was higher in the CONT diet, followed by the ORG diet. However, the economic conversion rate was lower for CONT, SBS, TRO, and MIX. Overall, using organic diets of animal origin impacted the growth performance of gilthead seabream, but it is still a promising approach.This project had been developed with the collaboration of the Biodiversity Foundation (Spanish Ministry for Ecological Transition and the Demographic Challenge), through the Pleamar Program, co-financed by the European Maritime and Fisheries Fund (EMFF).

Fish oil substitution by soybean oil in Diplodus puntazzo: Performance fatty acid profile and liver histology

[EN] The present study was performed to determine the effect of soybean oil on the performance and liver histology in sharpsnout sea bream. Four experimental diets were formulated containing 0%, 25%, 50% and 75% of soybean oil substituting of fish oil. Fish weighing 35 g were fed for 84 days. Increasing the level of soybean oil had no significant effects on growth and feed efficiency parameters. Biometrics, body composition, protein- and energy- efficiency were not affected by the fish oil replacement. Muscle and liver fatty acids reflected fish oil substitution. Moreover, histology did not show statistical differences among treatments.This research was supported by grants from the Planes Nacionales de Acuicultura (JACUMAR) in Spain.Nogales Mérida, S.; Martínez-Llorens, S.; Moñino López, AV.; Jover Cerda, M.; Tomas-Vidal, A.

Relation of quality and sensory perception with changes in free amino acids of thawed seabream

[EN] This study aimed to investigate how the freshness before frozen storage affect the quality and sensory characteristics of seabream in different commercial presentations and to correlate the findings with free amino acids composition. The fish were slaughtered, allocated to three processing treatments (whole, gutted and filleted) and stored at refrigeration (0±1 °C) for different times (5, 9, 11 and 18 days) before one-month frozen storage (¿30 °C). After this time, physicochemical (pH, TVB-N, TBARS and free amino acids), bacterial count and sensory evaluation (Torry Index & Quality Descriptive Analysis -QDA-) were studied. Significant differences were found among treatments over time for TVB-N, TBARS and bacterial growth. The quality index (Torry) exhibited a gradual decrease. QDA showed that fillets had the lowest assessment. Free amino acids contents varied significantly during frozen storage with a particular behavior that depended on the previous treatment applied and the fish freshness degree (elapsed days before frozen)This study was financially supported by the Gobierno de Aragón (Grupo Consolidado de Calidad y Tecnología de la Carne, Ref: A04), Instituto Agroalimentario Mixto de Aragón (IA2) and Institute of Animal Science and Technology, Polytechnic University of Valencia.Calanche, J.; Tomas-Vidal, A.; Martínez-Llorens, S.; Jover Cerda, M.; Alonso, V.; Roncales, P.; Beltrán, J.

Replacement of fish oil with vegetable oil blends in feeds for greater amberjack (Seriola dumerili) juveniles: effect on growth performance, feed efficiency, tissue fatty acid composition and flesh nutritional value

[EN] This study was undertaken to assess the effects of fish oil (FO) substitution by a mixture of alternative vegetable oils (VO) on Seriola dumerili culture performance. A 154-day feeding experiment was conducted using juveniles (39.2 +/- 1.6g average weight). Three isolipidic and isoenergetic meal-based diets were formulated varying their lipid component. The control diet contained 100% FO (FO100), whereas diets VO50 and VO100 included 1/2 of oil blend and all the oil from blend of palm oil (PO) and linseed oil (LO) as substitute for FO, respectively. Dietary regime did not significantly affect growth performance, biometric indices, feed efficiency, plasma chemistry and liver and muscle lipid contents. Nonetheless, dietary VO inclusion impacted on the fatty acid profile of target tissues, especially in the liver. Fatty acid profiles of the fillets reflected those of the dietary oils except that there was apparent selective utilization of palmitic acid (C16:0) and oleic acid (C18:1n-9) and apparent selective retention of long-chain polyunsaturated fatty acids, especially eicosapentaenoic acid (EPA, C20:5n-3) and docosahexaenoic acid (DHA, C22:6n-3). The nutritional value and the potential ability to prevent the development of coronary heart diseases of the flesh lipid fraction decreased with gradual FO substitution.Ministerio de Ciencia e Innovacion (MICINN), Grant/Award Number: AGL2011-30547-C03-02Monge-Ortiz, R.; Tomas-Vidal, A.; Rodriguez-Barreto, D.; Martínez-Llorens, S.; Perez, J.; Jover Cerda, M.; Lorenzo, A.
