| The aim of this study was to increase rhamnolipid production by formulating media using kefir and fish meal for Pseudomonas aeruginosa strains isolated from different environmental resources. The strains, named as H1, SY1, and ST1, capable of rhamnolipid production were isolated from soil contaminated with wastes originating from olive and fish oil factories. Additionally, P. aeruginosa ATCC 9027 strain, which is known as rhamnolipid producer, was included in the study. Initially, rhamnolipid production by the strains was determined in Mineral Salt Medium (MSM) and then in media prepared by using kefir and fish meal. The obtained rhamnolipids were purified and quantified according to Dubois et al. (1956). The quantity of rhamnolipids of ATCC, H1 and SY1... |

| There are several ingredients that can replace those commonly used in the manufacture of animal ration in order to reduce production costs, as tilapia by products meal. However, as byproducts, more studies should be done to achieve the exact effects over the final product. An experiment was carried out aiming at evaluate the effects of the inclusion of five different levels (0%, 2%, 4%, 6% and 8%) of tilapia (Oreochromis niloticus) byproducts meal (TM) on poultry diets on carcass yield and sensory characteristics of broiler chicken meat. 480 one day old chicks, Cobb strain, were used to set the experiment with five treatments arranged in completely randomized design, with six replicates, and 16 birds per experimental unit. At the end of the experiment (42... |

| Three meals were formulated from the earthworm (Endrilus eugineae) and maggot (Musca domestica) and fish (Engraulis encrosicolus). These meals were evaluated as a potential replacement for fishmeal. This is because fishmeal could be very expensive at times. The three meals were used in feeding the catfish (Heterobranchus isopterus) fry for 30 days. The study was conducted in 1991 at the Institute of Renewable Natural Resources Farm, University of Science and Technology. Two replicates were done using four hapas in each replicate. Each hapa was stocked with 50 fry and fed. Those in the fourth hapa were not fed to ascertain the effect of supplementary feeding on the growth of the fish. Weight increment was found to be less in the fourth hapa than the... |

| Partial or total replacement of fish meal by a mixture of plant protein (PP) sources (corn gluten, wheat gluten, extruded peas, rapeseed meal and sweet white lupin) balanced with indispensable amino acids was examined in juvenile gilthead sea bream over the course of a 6-month growth trial. A diet with fish meal (FM) as the sole protein source was compared to diets with 50%, 75% and 100% of replacement (PP50, PP75, and PP100). The possible influence of diets on growth performance, plasma metabolites, gut integrity, liver structure, anti-oxidant and immune status was evaluated. Final body weight was progressively decreased with PP inclusion, but in PP50 and PP75-fed fish, feed efficiency (FE) was significantly improved and specific growth rates remained... |

| In order to improve the formulation of diets fed to reared Penaeus vannamei, the effects of soya bean and fish meals on the growth, survival, and the characteristics of the hepatopancreas and digestive enzymes of the species were studied. Four soya bean meal concentrations (0, 5, 15, 40%), four fish meal concentrations (0, 5, 15, 30%), two forms of soya bean meal and three fish meals of different geographical origin were tested. Experimental conditions were as follows: ten individuals were placed in each tank (0.5 m2 ) and two tanks were subjected to each treatment. Food was given twice a day (08-09.00 h and 19.00 h) at 10% of the initial weight each day. For biochemical analyses, nine individuals per treatment were used for the determination of the... |

| Dans le but de promouvoir l’alimentation du Tilapia en élevage dans les fermes aquacoles tunisiennes, quatre aliments composés secs ont été élaborés à partir de matières premières conventionnelles et contenant différents taux de farine de poisson de fabrication locale (0 %, 10%, 20 % et 30 %). Ces aliments composés, de 36 % de protéines brutes et 6 % de lipides, ont été testés sur des alevins de Tilapia de poids moyen initial de 2 g. Après 45 jours d’expérimentation, les poids moyens finaux ont varié entre 21,33 g et 29,34 g selon les traitements. Les meilleurs taux de croissance et de transformation alimentaire ont été obtenus par les aliments contenant 20 % et 30 % de farine de poisson, avec des taux de croissance spécifiques (TCS) respectifs de 5,82 %... |

| Un diseño experimental completamente aleatorizado se desarrolló, durante 7 semanas, para evaluar el efecto de niveles de inclusión (0, 5, 10 y 15%) de harina de cangrejo (HC) Gecarcinus ruricola, sobre el crecimiento del camarón Litopenaeus schmitti. Los juveniles de camarón (peso medio inicial 0.44 ± 0.02 g), se distribuyeron en recipientes con 40 L de agua de mar a una densidad de 17.8 g/m2. El contenido de metales pesados (Pb, Cd, Cu, Zn) de la HC, dietas y camarones, se determinó por el método de absorción atómica. La calidad proteica de los alimentos experimentales se evaluó por el método del cómputo químico. Las dietas que contenían HC promovieron los más altos crecimientos (P< 0.05). Los juveniles que consumieron alimento con 5% de HC... |

| Abstract: The objective of this work was to determine the apparent digestibility coefficient (ADC) of crude protein, crude energy, fat, and dry matter of fish protein hydrolysate (FPH), made of by-products of Nile tilapia (Oreochromis niloticus) and whole sardines (Cetengraulis edentulus), and to evaluate the productive performance and muscle fiber growth of Nile tilapia post-larvae. Two trials were conducted, the first one to determine the digestibility in 120 fingerlings (70.0±2.0 g), and the second one to evaluate the productive performance of 375 post-larvae, with three days of age, which were distributed in 25 aquaria with 30 L of useful volume. Five diets were prepared based on vegetable ingredients, to which fish were included at 0, 2, 4, 6, and 8%... |

| Fish require diets containing 30 to 55% of crude protein and an amino acid supply precisely adapted to meeting the needs for optimal growth. Fish meal is an ideal protein source for aquafeed because it has a high protein level (65% to 72%) with an ideal proportion of all ten indispensable amino acids that meet the requirements of all fish species. However, finding alternatives to fish meal has become an absolute necessity in order to reduce the reliance of aquaculture on marine ingredients. Animal by-product meals (meat meal, bone meal, blood meal, poultry by-product meal, hydrolysed feather meal) are used as alternative protein sources in aquafeed in extra-European countries. Since the use of animal protein in aquafeed is forbidden in Europe (except non... |

| Para los organismos mundiales de referencia, los residuos de metabolitos de Nitrofuranos en tilapia, camarón, harina de pescado y balanceado son considerados como un factor de riesgo en la salud pública y como limitante en el desarrollo económico de cualquier país donde se comercializa este tipo de productos. Estas razones junto con el avance de metodologías analíticas cada vez más sensibles, han hecho que los requisitos de sanidad e inocuidad exigidos sean cada vez más estrictos, especialmente cuando el destino del producto es la exportación. En Ecuador, en su continua intención de ofrecer productos inocuos y para dar cumplimiento con las exigencias del mercado internacional en relación a las normativas de calidad, se ha visto en la necesidad de renovar... |

| Considering the need to help the Cuban shrimp culture industry remain profitable, and the impact that feeding has on production costs, a research series was designed to evaluate new formulations that improve white shrimp Litopenaeus schmitti growth and reduce feeding costs. Five completely randomized experiments with 3 replicates per treatment were conducted. Juveniles (0.2-0.5 g) from the experimental farm were used. Trials were conducted at the Centro de Obtención y Cría de Larvas de Santa Cruz del Sur, Camaguey, and the Complejo Camaronero de Tunas de Zaza, Sancti Spiritus. In the first trial, 40-l plastic experimental units with 10 shrimp/unit were used to test the response of L. schmitti to the partial and total substitution (46, 59, 75, 88 y 100%) of... |

| Foi avaliada a influência da substituição da farinha de peixe pela farinha de minhoca (Eisenia foetida) no crescimento de pós-larvas de tilápia nilótica (Oreochromis niloticus). A farinha de peixe, que correspondeu a 50% da proteína da dieta, foi substituída pela farinha de minhoca nos seguintes níveis: 0%, 20%, 40%, 60%, 80% e 100%. Os peixes foram alimentados à vontade, quatro vezes ao dia, sendo pesados e medidos aos 21 e 41 dias de experimentação. O delineamento experimental foi o completamente casualizado, com quatro repetições por tratamento e 20 peixes por unidade experimental. Os dados coletados foram analisados pela ANOVA, sendo as médias posteriormente classificadas pelo teste de Tukey (5%). Após 21 dias, não houve diferença significativa entre... |
