The Pacific red snapper, Lutjanus peru, is a commercially important species throughout its distribution range, making it a good alternative for aquaculture; however, there is few information regarding environmental conditions and their influence on early development of this species. Temperature is one of the main factors affecting embryo and larval...

This paper aimed to evaluate the effects of feeding rate and the hormonal treatments for spawning induction on the condition factor, and the reproductive performance of the striped catfish, Pangasianodon hypophthalmus. A commercial diet with 35% of protein in three feeding rates-1%, 2%, and 3% biomass, were supplied for 184 days-and two hormonal me...

Objetivo. El propósito del presente trabajo fue evaluar el efecto del ácido tánico y de las proteasas para eliminación de la capa adherente en huevos fecundados de bagre asiático, P. hypophthalmus, para mejorar las condiciones de incubación. Materiales y métodos. Se utilizó ácido tánico a 0.5 g L-1 por 5 min, proteasa a 5 mL L-1 por 8 min para la e...

Se evaluó el efecto de inhibidores naturales y sintéticos de la enzima aromatasa sobre el crecimiento, supervivencia y masculinización en crías de tilapia del Nilo. Cinco flavonoides: crisina (CRI), 7-hidroxiflavona (7-HF), apigenina (NA), naringenina (NAR) y 7-metoxiflavona (7-MF) a 1 000, 1 500 y 2 000 mg kg-1; un compuesto no esteroideo: letrozo...

Objectives. To assess the effect of different farming methods on the condition factor and egg production of female tilapia brooders. Materials and methods. Three different brooder stocks were kept under three experimental treatments: TC - green water (control), T1 -aquamimicry, and T2 - biofloc. Each broodstock was repeated in each experimental tre...

The steady demand for fish in the aquaculture sector has led to the study and implementation of new compounds of natural origin which seek to standardize and maximize production by ensuring reproductive performance. Microalgae have emerged as a renewable source with specific nutritive qualities that allows the enhancement of captive breeding, and t...

The longfin yellowtail Seriola rivoliana is an emerging commercial species in aquaculture. However, there is little information regarding environmental conditions and their influence on early larval development that come from natural spawning. Temperature is one of the main factors affecting embryo and larval development. Therefore, the purpose of...

This study aimed to assess the growth performance, antioxidant and immune responses of red tilapia (Oreochromis sp.) reared in seawater with two stocking densities (D1, 120 fish/m3; D2, 240 fish/m3) with biofloc plus probiotics. For each density, juvenile red tilapia (6.7 ± 0.2 g) were cultured under three different experimental conditions: clear s...

The oceans have absorbed more than 40% of the carbon dioxide (CO 2) generated by anthropogenic activities, causing a decrease in the average pH of 0.1 units in seawater since preindustrial times. This phenomenon has been called ''ocean acidification.'' This change poses serious threats to the cultivation of oysters and especially to larval and spat...

Background: Shrimp farming is evolving from semi-intensive to hyper-intensive systems with biofloc technology and water recirculation systems. Objective: To evaluate the transcriptional response promoted by biofloc on shrimp (Litopenaeus vannamei) under a recirculating aquaculture system (RAS). Methods: Quantitative real-time RT-PCR was used to m...

In the present study, the potential of three isolated microalgae strains from Bahía de La Paz, Baja California Sur, Mexico and identified as Schizochytrium sp. (Inner key: LPU-1), Chaetoceros sp. (LPU-2), and Chaetoceros sp. (LPU-3) for the cultivation of the rotifer Brachionus plicatilis was tested. The effects of isolated strains on the populatio...

In the present study, quantitative real-time RT-PCR was used to monitor the transcriptional responses of seven key genes related to some innate immune pathways in shrimp postlarvae after being placed in a recirculating aquaculture system (RAS) with or without biofloc (BF or no-BF). Each system consisted of the main tank with 400 L of seawater and s...

The Pacific red snapper Lutjanus peru, is an attractive species for aquaculture. Its reproduction in captivity under controlled conditions has not been feasible, due to the lack of knowledge on its basic reproductive biology and management conditions. For the first time, we evaluated the first sexual maturity stage of captive Pacific red snapper, b...

It is a technical report about the colection of freswater fishes from Sonora, Mexico and the database made with Biotica software by CONABIO.

Efecto del fotoperiodo y la temperatura sobre la composición bioquímica en reproductores silvestres de cabrilla sardinera, Mycteroperca rosacea (Streets, 1877) RESUMEN. Se estimó el factor de condición (K), el índice gonadosomático (IGS), hepatosomático (IHS) y de grasa visceral (IGV), así como la composición bioquímica en diferentes tejidos de rep...

Condition factor (K), gonadosomatic index, (IGS), hepatosomatic index (IHS) and fat visceral index (IGV) were estimated and the biochemical composition in different tissues of wild leopard grouper broodstock was determinate too, in order to evaluate them along a reproductive cycle and see the relationship of these changes with respect to the water...

TESIS Que para obtener el grado de Doctor en Ciencias Uso, Manejo y Preservación de los Recursos Naturales P r e s e n t a (Orientación Acuicultura) CICLO REPRODUCTIVO Y COMPOSICIÓN BIOQUÍMICA DE LA CABRILLA SARDINERA, Mycteroperca rosacea (STREETS), EN EL MEDIO NATURAL

The leopard grouper Mycteroperca rosacea is an endemic species from the northwestern coast of Mexico and, like other serranid fishes, it has a high commercial value, hence, it is a good candidate for cultivation. This study aimed to describe the reproductive cycle of the leopard grouper in the wild as a step toward evaluating its aquaculture and re...

The register of viviparous fish species that ocurr in the Oaxacan hydrological basins in the protected, natural área Tehucan-Cuicatlan (the Scientific Collection of Continental fishes of CIIDIR Oaxaca No. OAX-PEC-122-0302) was revised. In order to make the revisión, five collections were made between september 2005 and march 2006, two collections w...

La ictiofauna de la Reserva de la Biosfera Tehuacan-Cuicatlán es poco conocida y varias especies se están extinguiendo, debido al impacto ambiental provocado por las diferentes actividades humanas. El objetivo de esta investigación es conocer la diversidad biológica y la distribución en el espacio de las especies de peces de agua dulce en el área o...
