Carbon and nitrogen stable isotope values were determined in Pacific white shrimp (Litopenaeus vannamei) with the objective of discriminating animals produced through aquaculture practices from those extracted wild. Farmed collected at semi-intensive farms Mexico Ecuador. Fisheries-derived shrimps caught different fishing areas representing two estuarine systems four open sea locations (δ 13 C VPDB δ 15 N AIR ) allowed clear differentiation wild farmed animals. isotopically enriched (−16.99‰...
Abstract Alternative and sustainable ingredients are currently needed to replace fishmeal in aquaculture. In addition plant-derived ingredients, novel approaches have been implemented evaluate different types of insect meals as for animal nutrition. the present study Seven experimental diets were formulated effects varying levels Madagascar cockroach meal ( Gromphadorhina portentosa ) Spirulina Arthrospira platensis on growth, survival, metabolic turnover, hepatic protection, nutrient...
The relative contribution of the dietary nitrogen supplied by fish meal and a biofloc to growth Pacific white shrimp was evaluated using stable isotope analysis. Biofloculated material obtained from an experimental tilapia culture system. Five formulated diets were supplied. Two them consisted in isotopic controls having only or as protein source. Three mixed with varying proportions these ingredients on basis (75:25, 50:50 25:75). At end trial, survival rates similar (92–100%) but...
Two feeding trials were carried out to evaluate the effect of diets containing corn or peanut grains naturally contaminated with aflatoxins on growth, feed intake, survival, and histological response white shrimp Litopenaeus vannamei. In trial 1, four experimental formulated contain 0, 500, 1000, 2000 µg kg–1 total (TA) fed L. vannamei juveniles for 28 days. 2, six 10, 20, 40, 60, 120 TA 64 Feed intake weight gain significantly affected by presence from grains. conversion rate increased a...
In order to become a more profitable and sustainable industry, the aquaculture sector is constantly exploring alternative nutrient sources. present study, natural stable isotope signatures of different animal-, plant- microbial-derived ingredients were determined evaluate assimilation dietary nitrogen in Pacific white shrimp. Experimental diets manufactured replace fish meal squid with microbial- derived (48 66 % inclusion) also used as additives (4%). Ingredients study their effects on...
The safety and effectiveness of four aluminosilicate-based products (Novasil Plus, Zeolex Extra, Mycofix Select, Fixat) were tested for 42 days on juvenile Pacific white shrimp, Litopenaeus vannamei, fed diets containing corn grains that had been previously inoculated with Aspergillus parasiticus then sterilized. Two control diets, one uncontaminated another contaminated the grain, elaborated to contain a final concentration 0 75 μg kg–1 total aflatoxins. Both formulated 38% crude protein 8%...
The natural nitrogen stable isotope signatures (δ 15 N) found in poultry by-product meal (PBM) and fish (FM) were used to estimate the relative contribution of dietary supplied by both ingredients somatic growth juvenile channel catfish Ictalurus punctatus.Six isonitrogenous isoenergetic experimental diets formulated using FM PBM.Two these consisted isotopic controls having only one ingredient supplying nitrogen, either or PBM.Four combined with varying proportions order supply high PBM...
Apparent digestibility coefficients (ADC) of dry matter, crude protein (CP), and amino acids (AA) were evaluated in diets with six rendered by-products used to feed juvenile Pacific white shrimp: two poultry meals (poultry meal 1, 69% CP; 2, 72% CP), feather (89% one blood (96% pork (57% CP). Experimental formulated 30% the test ingredient 70% a commercial diet supplemented 1% chromium oxide as inert marker. AA contents ingredients, diets, leached feces determined by high performance liquid...
Abstract The nutritional contribution of the dietary nitrogen supplied by poultry by‐product meal ( PBM ) and fish FM to somatic growth Pacific white shrimp, Litopenaeus vannamei , was assessed means stable isotope analysis. Seven experimental diets were formulated with different proportions replacing . Practical replace 0, 35, 50, 65, 80, 95, 100% on a basis. At end experiment, there no significant differences in survival among treatments (89 ± 5%); however, final wet weights observed....
In this preliminary study we examined the application of dual stable isotope analysis (δ13C and δ15N) to identify origin skins meat derived from wild farmed crocodiles. Traceability protocols can benefit analytical techniques that are able distinguish or organisms. Scutes muscle samples were obtained crocodiles Crocodylus acutus (n = 14) C. moreletii 9). Isotopic values in scutes differed significantly between organisms, difference being higher for δ15N than δ13C values. When both isotopic...
We describe the genome sequences of three closely related mycobacteriophages, Kerberos, Pomar16, and StarStuff, isolated at similar times but from geographically distinct regions. All genomes are to those other subcluster A2 phages, such as L5 D29, temperate, have siphoviral virion morphologies.
Antecedentes.Debido a que no existen estudios sobre el lixiviación de nutrientes las heces camarón Litopenaeus vannamei, se diseñó presente estudio.Objetivos.Estimar la pérdida del blanco Pacífico (Litopenaeus vannamei).Métodos.Se utilizaron 15 juveniles 4.9 ± 1.0 g peso por cada uno cuatro acuarios replicados tratamiento.En un ensayo alimentación con una dieta referencia comercial, cual fue reprocesada para añadir 1% óxido cromo como marcador inerte y alginato sodio (aglutinante).El...
Apparent digestibility coefficients (ADC) for dry matter, energy, crude protein (CP), and amino acids (AA) were evaluated 4 feedstuffs used to feed juvenile white shrimp (Penaeus vannamei): fish meal (73.5% CP), potato concentrate (89.3% brewer’s yeast (42.5% crustacean (47.2% CP). Experimental diets included 30% of the test ingredient 69% a commercial diet supplemented with 1% chromium oxide as inert marker. Amino acid contents in ingredients, experimental diets, leached feces analyzed by...
