In Mexico, the tilapia Oreochromis provides one of most important sources animal protein and income in a wide variety communities throughout country, however, their culture production face severe problems because lack management information. Evaluated present study is degree morphological, meristic allozyme variation two strains, species hybrid from reservoirs fry farms (TFPF) an experimental system (EPS), to diagnose actual status among them. Twenty-two presumptive loci were utilized...
Determining the relative influence of biotic and abiotic factors on genetic connectivity among populations remains a major challenge in evolutionary biology management conservation species. North Pacific hake (Merluccius productus) inhabits upwelling regions California Current ecosystem from Gulf to Alaska. In this study, we examined mitochondrial DNA (mtDNA) microsatellite variation estimate levels differentiation M. productus relation role oceanographic features as potential barriers gene...
The common octopus of the Veracruz Reef System (VRS, southwestern Gulf Mexico) has historically been considered as Octopus vulgaris , and yet, to date, no study including both morphological genetic data tested that assumption. To assess this matter, 52 octopuses were sampled in different reefs within VRS determine taxonomic identity commercially valuable species using an integrative approach through analyses. Morphological confirmed is not O. determined it is, fact, recently described...
The octopuses Octopus hubbsorum and mimus are two species of that inhabit shallow waters the eastern Pacific Ocean. former is found in north, from Gulf California to Oaxaca, Mexico, whereas O. lives south, Peru Chile. To infer phylogenetic relationships between these we used mitochondrial genes cytochrome oxidase subunits I III, r16S with aim comparing their genetic distances those other sp. distance values both estimated per gene or concatenated were low (0%–1.6%) comparison interspecific...
Pteronotus davyi, Davy's naked-backed bat, is a tropical bat whose current distribution in Mexico covers the watersheds of Pacific and Gulf coasts Mexico, converges at Isthmus Tehuantepec, continues into Yucatan peninsula. We evaluated phylogeographic relationships among 18 populations using data from nucleotide sequence hypervariable II domain mitochondrial DNA control region 105 specimens. Extant were distributed over 3 geographic regions (Pacific Coast, Southeastern) that delineated...
Due to its morphological conservatism, the American funnel-eared bats of genus Natalus have had a complex taxonomic history. In Mexico only one species, N. stramineus, has traditionally been recognized. But recently new endemic lanatus, was described in region as sympatric sibling species stramineus. with geographic distribution extending from Panama, subsequently reassigned mexicanus. this study, we analyzed and molecular characters determine if two distinct (N. lanatus mexicanus) occur...
The octopus fishery in Mexico is supported by two species, Octopus maya and an vulgaris-like species that teuthologists have named O. vulgaris type I. main off the Yucatan Peninsula maya, whereas historically has Mexican east coast. Management policies protect this Veracruz Reef System (VRS) Gulf of Mexico, where artisanal fisherman catches it; however, specimens I harvested reef system share haplotypes with insularis, they cluster together a strongly monophyletic clade. insularis does not...
The geographic distribution of Octopus mimus Gould, 1852 is unclear, as most records are restricted to coastal localities Peru and Chile, some references have mentioned its presence off Central America. It unknown whether this octopus found Ecuador two previous unpublished suggested. aim the present study identify genetically main captured in a marine protected area known Reserva de Produccion Faunistica Marino-Costera Puntilla Santa Elena (REMACOPSE) peninsula, Ecuador. Samples collected...
An experiment was carried out to analyse the effects of substituting fish-meal (FM) with soya bean meal and shrimp protein hydrolysate (SPH) on percent survival, growth rate, feed efficiency molt frequency redclaw crayfish hatchlings, Cherax quadricarinatus. The performed in a closed recirculating-water system over 56-day period. Five diets were tested: control diet (SPH0) comprising 100% FM without SPH, four 2.5%, 5.0%, 10.0% 15.0% SPH substitution (diets SPH2.5, SPH5, SPH10 SPH15...
Knowledge on species taxonomic identity is essential to understand biological and biogeographical processes for studies biodiversity. Species the genus Tremoctopus have been confused in past are inconsistently identified. To clarify of diagnosis violaceus Delle Chiaje, 1830, an evaluation morphological meristic characters, as well morphometric indices genetic analyses, was undertaken. The analyzed octopod opportunistically collected mature female 640 mm total length, with a mantle length 135...
Abstract We describe the results of optimization process to induce triploidy in Pacific white shrimp, Litopenaeus vannamei, reported diploid and triploid chromosome numbers, time extrusion second polar body survival rate at nauplii larvae stage. The number was 88 (42.5%). observed eggs within 16 20 minutes post-spawning, higher frequency occurred 18 minutes. condition induced by application cold shock (10°C) after fertilization with a duration 15 obtained high eclosion (79%) comparison other...

Wagner's mustached bat (Pteronotus personatus) is an insectivorous distributed throughout America from Mexico to Brazil, which inhabits a range of habitats rain forests dry deciduous forests. There are two currently recognized species within the P. personatus complex, for we examined 235 cytochrome oxidase I (COI) sequences and 138 b (Cytb) in order explore its genetic variation as well Central South America. Our results reveal considerable differences structure inside this indicating five...
