This study was conducted to investigate the effects of dietary fructooligosaccharides (FOS) on growth, survival rate, digestive enzyms activity, and expression intestinal barrier function genes in tropical gar (Atractosteus tropicus) larvae. A total 960 larvae (0.030 ± 0.006 g) were fed three diets supplemented with increasing FOS concentrations (2.5, 5, 7.5 g kg−1) a control diet for 15 days. Results revealed that kg−1 supplementation improved weight gain, specific growth rate (p <...
The intracohort cannibalism present in tropical gar larvae (A. tropicus) generates great problems its culture, as other fish species around the world. addition of tryptophan (Trp) (10, 20, and 30 g/kg) a control diet (CD) without Trp were evaluated A. tropicus regarding growth, survival, cannibalism, behavior, digestive enzymatic activity, genes related to aggressiveness and/or two stages: 0–13 days after hatching (DAH); only cannibals (14–24 DAH). In first stage, no differences observed...
The tropical gar (Atractosteus tropicus) is a primitive freshwater fish of significant commercial importance in southeastern Mexico. However, its population danger due to habitat loss and overexploitation. Cultivation emerges as viable reproductive management strategy; yet further studies are crucial understanding molecular markers guiding management, differentiation, sexual maturation this species. We analyzed the expression five sex-related genes (foxl2, sox9, cyp17a1, dmrt1, cyp19a1)...
<p class="1Body">Common snook (<em>Centropomus undecimalis</em>) is a marine species with high aquaculture potential; although its digestive physiology still unknown and knowledge of that could allow the development balanced feed for commercial culture this fish. The objective study was to partially characterize proteases in <em>C. undecimalis</em> using electrophoretic biochemical techniques. A total 50 wild juveniles were used determine optimal values pH...
The effect of adding inulin to balanced diets for tropical gar (Atractosteus tropicus) larvae on growth, survival, digestive enzyme activity, and antioxidant activity was evaluated. were supplemented with 0.5, 1.0, 1.5, 2.0, 2.5% in addition a control diet (0% inulin). A total 1800 A. tropicus distributed 18 tanks used; the fed five times day (8:00, 11:00, 13:00, 15:00, 18:00) Artemia nauplii from absorption yolk (from 3–7 days after hatching, DAH) up 10 DAH, which mixed experimental feeds...
Five experimental diets containing different lipid sources, fish oil (D1), soybean lecithin (D2), corn (D3), canola (D4) and olive (D5), were evaluated in Atractosteus tropicus larvae for the relative gene expression of enzymes fatty acid synthase (fas), acetyl-CoA carboxylase 1 (acc1) carnitine palmitoyltransferase 1C (cpt1c), addition to their effects on larval growth, survival cannibalism during a 30-day feeding trial. Higher growth obtained treatments D1 D2, lower performance D3, D4 D5....
Aquaculture practices expose fish to several factors that may generate stress, modifying the balance between production of reactive oxygen species (ROS) and activity antioxidant defenses induce cell damage. Alpha-tocopherol (VE) improves capacity against ROS in fish. A 50-day trial with longfin yellowtail (Seriola rivoliana) juveniles was conducted compare dietary supplementation 500 mg/kg VE a control diet without on growth, lymphoid tissue enzymatic activity, immune-system-related gene...
Abstract Two experiments were conducted to evaluate the initial stocking density in larvae of Bay snook, Petenia splendida , and Mexican mojarra, Cichlasoma urophthalmus using a recirculation system. Five densities (0.5, 1, 5, 10, 20 larvae/L) evaluated by triplicate for 45 d. Weight total length (TL) measured every 15 d, fish production was calculated each density. The stocked at lowest (0.5 1 presented highest growth both species: C. (0.78 g 45‐mm TL, 0.76 respectively) P. (0.80 52‐mm 0.79...
The tropical gar (Atractosteus tropicus) is an economically and socially important freshwater fish species from southeastern Mexico, with high aquaculture potential. This study determined the expression of acetyl-CoA carboxylase (ACC1), fatty acid synthase (FAS), carnitine palmitoyl transferase 1 (CPT1C) in several tissues adult specimens, as well early ontogeny stages gar. Partial sequences all genes were obtained for brain, liver, muscle, mesenteric adipose, kidney, testis, gill, heart...
A total of 300 Centropomus undecimalis juveniles, with an average initial weight 3.16 0.28 g and length 7.17 0.22 cm, were reared for eight weeks using a recirculating system to determine the dietary protein requirement their growth survival. The eect ve experimental diets containing 40, 45, 50, 55 60% content two salinities (brackish water, BW at 5 UPS marine MW 36 UPS) assessed. Fish fed times per day 2.5% biomass. All treatments performed in triplicate,recording individual every 15 d,...
ABSTRACT Short-tailed pipe fish (Microphis brachyurus) is a freshwater organism with high economic potential for the aquarium hobby, so it necessary to implement methods promote its culture through studies of digestive physiology. General activities acid and alkaline proteases were evaluated, as well effect pH, temperature inhibitors. The optimal pH stomach was 2, while intestinal 10. Optimal acidic 35 ºC, 45 ºC. Thermal stability showed resistance at ºC both (above 100% residual activity)....
ABSTRACT In the Southeast of Mexico, there are many native cichlids with commercial interest such as redhead cichlid (Vieja melanurus) and twoband (V. bifasciata), which have a great local demand excellent meat quality. However, it is necessary to implement their culture based on nutrition studies digestive biochemistry. This study’s objective was characterize these two cichlids’ proteases (pH, temperature, inhibitors) through biochemistry techniques. Results showed that V. melanurus...
We determined the effects of sodium propionate (SP) added to diets Atractosteus tropicus juveniles with respect growth, survival, digestive enzyme activity, and expression genes that are associated immune system. Five treatments (0, 0.5, 1.0, 1.5, 2.0%) were evaluated in triplicate on 180 fish (3.65 ± 0.12 g) distributed among 15 (70 L) tanks. The fed five times a day 5% feed relation biomass organism. treatment 0.5% SP showed final weight value 25.7 4.5 g, absolute gain (AWG) 21.93 4.39...
