Abstract:
Eimeria chollaensis sp.nov. (Apicomplexa: Eimeriidae) is described from the contents of the spiral valve of the round stingray, Urolophus halleri Cooper (Rajiformes: Dasyatidae), from the Gulf of California, Sonora, Mexico. Oocysts are ovoid, 13.3 × 9.7 (11.2–16.0 × 8.0–10.8) μm, with a smooth, thin, single-layered wall. Micropyle, polar granule, and oocyst residuum are absent. Sporocysts are ovoid, 8.9 × 4.9 (8.0–10.0 × 4.2–5.6) μm, and possess a Stieda body but no substieda body. Sporozoites are elongate, with numerous transverse striations anteriorly and a single, ovoid refractile body. The

Abstract:
<p>As for most batoid species, little is known about the basic biology of the Venezuela round stingray Urotrygon venezuelae (Urotrygonidae). This study presents information about the reproductive biology of the species, including fecundity, embryonic development stage, relationship between maternal size and fecundity, gonadosomatic (GSI) and hepatosomatic (HSI) indices, sex ratios, maturity size and size at birth. With all this information, a preliminary reproductive cycle is proposed. A total of 269 specimens were caught with beach seine in Salguero beach, Colombian Caribbean Sea, betwe

Abstract:
The intensity of the Pacific salmon fry migration in the Amur basin depends on the water level and floods; In the clear water of the river Anyuy rolled migration is round-the-clock, but the intensity of migration shifts to the dark time of day. In recent years, the effectiveness of reproduction is not stable, there are "failures" when the number of young people decreases dramatically, which determines the need for constant observations of the stingray for adjustments of catch forecasts. The assessment of the total number of young people sliding into the Amur River basin shows the comparability

Abstract:
AbstractOrganic contaminants are known to affect a suite of physiological processes across vertebrate clades. However, despite their ancient lineage and important roles in maintaining healthy ecosystems, elasmobranchs (sharks, skates, and rays) are understudied with regard to sublethal effects of contaminant exposure on metabolic processes. Perturbations resulting from contaminant exposure can divert energy away from maintaining physiological homeostasis, particularly during energetically challenging life stages, such as pregnancy and embryonic development.

Abstract:
Biting has been observed to be an important component of male mating behavior in several elasmobranch species. I observed male biting during courtship and mating in a population of Urolophus halleri, the round stingray, in the Sea of Cortez. Females allow males to bite the posterior and medial edge of their pectoral fin during courtship yet often appear to struggle to dislodge the male after they have been bitten. During mating the male bites the anterior edge of the females' pectoral fin and the female is passive. In response to this biting behavior females have relatively thicker discs than

Abstract:
<p> Polychlorinated biphenyls (PCBs) negatively affect reproduction across taxa. However, how PCBs influence elasmobranchs is not well known. I hypothesized that acute PCB exposure would negatively impact reproductive parameters of newly-mature round stingrays (<i>Urobatis halleri</i>). To determine the acute effects of PCBs on steroidogenesis, male stingrays were injected with either Aroclor-1254 or vehicle (sesame-oil) and held for 24 hrs. Testicular mRNA expression for steroidogenic acute regulatory protein and 3&beta;-hydroxysteroid dehydrogenase decreased with 24 hrs exposure to Aroclor-1
