| fine structure of chloromyxum menticirrhi n. sp. (myxozoa) infecting the urinary bladder of the marine teleost menticirrhus americanus (sciaenidae) in southern brazil. | a myxosporidian was found in the urinary bladder of the teleost menticirrhus americanus linnaeus, 1758 (sciaenidae) collected from the south atlantic coast of brazil. polysporic amoeboid plasmodia containing sporoblasts, developing pansporoblasts and spores were free in the bladder lumen. the prevalence of infection was 17.64% (15/85). unfixed spores were spherical to subspherical, on average 10.5microm long, 9.8microm wide and 10.1microm thick (n=25), and fixed spores measured 10.1 x 9.5 x 9.7m ... | 2009 | 19211236 |
| cytogenetic studies in brazilian marine sciaenidae and sparidae fishes (perciformes). | fishes from the families sciaenidae and sparidae, the former comprising coastal species associated with shallow waters on the continental shelf and the latter composed of typically marine species, are of significant economic value. karyotypic data are available for about 20% of the total number of species in these groups. in the present study, cytogenetic analyses were carried out in three sciaenidae species, menticirrhus americanus, ophioscion punctatissimus and pareques acuminatus, as well as ... | 2008 | 18551402 |
| heavy metal levels in fish from coastal waters of uruguay. | copper, mercury, and zinc levels were determined in muscle and liver (n = 163) of seven fish species caught in coastal waters off montevideo and piriapolis (control site): odontesthes spp., mugil platanus, micropogonias furnieri, urophycis brasiliensis, cynoscion guatucupa, menticirrhus americanus, and mustelus schmitti. the local population commonly uses these species for consumption. heavy metal concentrations determined in this study were generally below those obtained for fish caught in arge ... | 2005 | 15883670 |
| spatial distribution and seasonality of ichthyoplankton and anthropogenic debris in a river delta in the caribbean sea. | temporal changes in larval fish species composition and abundance compared with other components of the seston are described in four estuarine habitats in the atrato delta, colombia. in comparison with zooplankton, fish larvae and egg density and anthropogenic debris abundance were low in the south atrato delta. transparency, water temperature and chlorophyll a were the major factors influencing the spatiotemporal distribution of ichthyoplankton in the delta. the most abundant fish larvae were a ... | 2017 | 28138987 |
| sciaenid inner ears: a study in diversity. | sciaenid fishes (family sciaenidae) could potentially serve as models for understanding the relationship between structure and function in the teleost auditory system, as they show a broad range of variation in not only the structure of the ear but also in the relationship between the ear and swim bladder. in this study, scanning electron microscopy (sem) was used to investigate inner ear ultrastructure of the atlantic croaker (micropogonias undulatus), spotted seatrout (cynoscion nebulosus), ki ... | 2001 | 11910172 |
| poecilancistrium caryophyllum and other trypanophynch cestode plerocercoids from the musculature of cynoscion nebulosus and other sciaenid fishes in the gulf of mexico. | examination of over 3,000 fish, all sciaenids, has shown that plerocercoids of poecilancistrium caryophyllum infect cynoscion nebulosus, bairdiella chrysura, sciaenops ocellata, c. arenarius, micropogonias undulatus, and pogonias cromis in mississippi sound. in addition to p. caryophyllum, a pseudophyllidean-like trypanorhynch also infected c. nebulosus and m. undulatus. pseudogrillotia pleistacantha selectively infected large p. cromis, pterobothrium heteracanthum infected m. undulatus, and pte ... | 1977 | 915606 |
| the structure and evolution of parvalbumins. i. amino acid compositional studies of parvalbumins from four perciform species. | 1. parvalbumins were isolated from the white muscle of cynoscion regalis, leiostomus xanthurus, and menticirrhus americanus of the sciaenidae and pomatomus saltatrix of the pomatomidae. 2. menticirrhus contains three isoparvalbumins. the other species contain two isoparvalbumins which are designated "fast" and "slow" in accord with their electrophoretic mobilities. measurements of the denatured molecular weights show the "slow" isoparvalbumins have slightly larger apparent molecular weights, but ... | 1975 | 1159797 |
| parvalbumin correlates with relaxation rate in the swimming muscle of sheepshead and kingfish. | parvalbumin is a muscle protein that aids in relaxation from contraction. parvalbumin binds myoplasmic ca(2+) during contractions, reducing calcium concentration and enhancing relaxation. different isoforms of parvalbumin have varying affinities for calcium, and relaxation rates in skeletal muscle may be affected by variations in the isoforms of parvalbumin expressed. this study examines the effect of expression levels of parvalbumin isoforms on relaxation rate in the sheepshead, archosargus pro ... | 2006 | 16391345 |
| permanent genetic resources added to molecular ecology resources database 1 december 2011-31 january 2012. | this article documents the addition of 473 microsatellite marker loci and 71 pairs of single-nucleotide polymorphism (snp) sequencing primers to the molecular ecology resources database. loci were developed for the following species: barteria fistulosa, bombus morio, galaxias platei, hematodinium perezi, macrocentrus cingulum brischke (a.k.a. m. abdominalis fab., m. grandii goidanich or m. gifuensis ashmead), micropogonias furnieri, nerita melanotragus, nilaparvata lugens stål, sciaenops ocellat ... | 2012 | 22448966 |
