Background Bacterial infections are responsible of high economic losses in aquaculture. Mexican golden trout ( Oncorhynchus chrysogaster ) is a threatened native trout species that has been introduced in aquaculture both for species conservation and breeding for production and for which no studies of bacterial infections have been reported. Case p...

The zebrafish is a model organism used to study organogenesis during vertebrate development; however epidermis development has been the focus of only a few studies. Thus, new methodologies to highlight and study epidermal cells could be valuable to deepen our understanding of skin development. Large-scale mutagenic screenings have already identifie...

The spatiotemporal effects of a bottom net used in an artisanal multispecific penaeid fishery at Celestun Lagoon, Mexico, were evaluated. Selectivity experiments, based on the covered codend method, were carried out with two bottom nets operating simultaneously but using different mesh size codends: 13 mm (MS13: currently used in the fishery) and 2...

A comparative analysis of three length based methods for estimating growth of the tilapia Oreochromis aureus (Perciformes: Cichlidae) in a tropical lake of Mexico. Several methods are now available to estimate fish individual growth based upon the distribution of body lengths in a population. Comparative analyses of length-based methods have been u...

Esta investigación se llevó a cabo en las instalaciones del Centro Regional de Investigación Acuícola y Pesquera Pátzcuaro (CRIAP-Pátzcuaro), con el objetivo de implementar dos modelos de acuaponia (Balsas flotantes y NFT), obteniendo los parámetros de producción de Acúmara (Algansea lacustris), y lechuga (Lactuca sativa L.), así como algunos indic...

Studies on the functional development of the digestive system and associated organs, especially during the change from endogenous to exogenous feeding, are of great importance for the success in the cultivation of native species with aquaculture potential. These studies identify the structures that are developing, establish the state of their struc...

En el segundo capítulo se analiza información pesquera de los tiburones incluidos en la cites, de importancia económica en las distintas pesquerías y regiones de México, en particular de los tiburones martillo, ya que en el aps realizado previamente se detectó que son los de mayor riesgo ecológico. El análisis pesquero se realiza con base en inform...

Los hábitats acuáticos del estado de Morelos han sufrido alteraciones en la composición de la fauna de peces, propiciada por la introducción de especies exóticas de forma accidental o con fines productivos en el mercado ornamental. El establecimiento de especies invasoras puede ocasionar alteraciones en la riqueza y abundancia de las especies nativ...

The rock oyster Crassostrea iridescens is an important fishery of the Michoacan coast, and with excellent potential for aquaculture. The purpose of this document is to analyze its reproductive characteristics. In this sense, commercial fishing samplings were carried in the harbor of Lazaro Cardenas and Zapote de Huahua, from February to December th...

Several methods are now available to estimate fish individual growth based upon the distribution of body lengths in a population. Comparative analyses of length-based methods have been undertaken mainly for marine species; nevertheless, limited information is available for inland species. Tilapia is one of the most important freshwater fisheries an...

El huachinango Lutjanus peru es la especie objetivo de la pesquería artesanal del estado de Michoacán; para conocer algunos aspectos biológico-pesqueros se realizó un estudio poblacional en 2002. Se calculó que la población alcanza una L∞ = 76.5 cm de longitud estándar (Ls), con un parámetro de curvatura de K =0.18 año1. Esta especie se reproduce e...

A seven month experimental work in laboratory was performed in order to determine how population density affects growth rate, survival an final biomass of native juvenile crawfish Macrobarchium tenellum from mexican Pacific coast. Crawfish were reared under three replicate treatments with different ammount of organisms:32, 16, 8 individuals per aqu...
