    Is there only one electric eel species?

In still water (shallow and temporary pools), we used one set of 20 m long gillnets, but in lotic environments (channels), we used two sets of 10 m long nets to standardize effort. The long lines with live bait, deployed only in rivers (deeper habitats), were left out overnight and checked the next morning.

    Cleaner fish - Wikipedia

    Cleaner fish interaction durations and memories of reoccurring clients are influenced by the neuroendocrine system of the fish, involving hormones arginine vasotocin, Isotocin and serotonin. Conspicuous coloration is a method used by some cleaner fish, where they often displaying a brilliant blue stripe that spans the length of the body. Figure 1. Biogeography and macroevolutionary dynamics of Coraciiformes. (a) Time-calibrated, maximum clade credibility tree showing species-level relationships of Coraciiformes based on 500 ultraconserved elements, fossil calibrations and maximum-likelihood topology constraints. The Striped Headstander is one of the most beautiful species of tetra from South America. It really looks like the big brother of the Threestripe pencilfish, Nannostomus trifasciatus.Anostomus anostomus attains a maximum length of about 15-18 cm. Sadly there are hardly ever exportations of ornamental fish from Guyana currently, so the beauty became rare in the hobby.

    3 Laboratory of Ichthyology, Department of Zoology, Federal University of Rio Grande do Sul, Porto Alegre, Brazil; The Pampas is a Neotropical biome formed primarily by low altitude grasslands and encompasses the southernmost portion of Brazil, Uruguay, and part of Argentina. Palavras-chave: Aspidoradini, Bahia, Corydoradinae, Região Neotropical, Taxonomia. Introduction Aspidoras Ihering, 1907 comprises 22 valid species (Eschmeyer et al., 2016) of small armored catfishes that are relatively broadly distributed in Brazil, mainly in the central and northeastern regions. Fish are gill-bearing aquatic craniate animals that lack limbs with digits.They form a sister group to the tunicates, together forming the olfactores.Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well.

    This study aimed to assess the feeding association between coral reef fishes and the hydrozoan Millepora spp. in two different reef systems (Tamandaré reefs and Fernando de Noronha archipelago) of Pernambuco State (north-eastern Brazil). A total of eight reef fish species, predominantly juveniles, were recorded feeding on colonies of Millepora spp. during 35 records. Abstract A central goal of animal ecology is to observe species in the natural world. The cost and challenge of data collection often limit the breadth and scope of ecological study.

Body length measurements and growth rate (GR) analysis are important steps in research on the ecology of early development stages of fish. In order to obtain accurate results, the lengths of field‐collected and preserved larvae must be corrected for shrinkage. China has planned 23 dams on the main stream of the Lancang (upper Mekong) River. The Chinese Government’s Thirteenth Five-Year Plan on Hydroelectricity Development (TFP) has goals to mitigate adverse effects on freshwater biodiversity. These measures are of international importance because China is the largest developer of hydropower projects. Herein we analyse the effects of the existing ...

There is increasing concern that certain chemicals in the aquatic environment can disrupt endocrine systems, leading to reproductive impairment and threatening survival of wild populations of invertebrates, fish, bird, reptiles, and wildlife. For the first time, we report that hypoxia is also an endocrine disruptor and poses a significant threat to the reproduction and hence sustainability of ...
