1. Diel periodicity and chronology of upstream migration in yellow-phase American eels (Anguilla rostrata)

Author:

Environmental biology of fishes 2017 v.100 no.7 pp. 829-838
ISSN:

Subject:
Anguilla rostrata; autumn; diel activity; eel; periodicity; rivers; spectral analysis; spring; statistical models; summer; time series analysis; West Virginia
Abstract:
... Yellow-phase American eel (Anguilla rostrata) upstream migration is temporally punctuated, yet migration chronology within diel time periods is not well-understood. This study examined diel periodicity, chronology, and total length (TL) of six multi-day, high-count (285–1,868 eels) passage events of upstream migrant yellow-phase American eels at the Millville Dam eel ladder, lower Shenandoah River ...

Salvelinus namaycush; brackish water; coasts; enzyme activity; fish; foraging; freshwater; genetic similarity; life history; osmolality; physiology; rearing; saline water; salinity; sodium; Arctic region; Canada
Abstract:
... Fertilization and development in salmonids occurs almost exclusively within freshwater environments (< 1 ppt). A less common life history strategy in this group of fishes is the brackish-water resident life history, where entire life cycles occur in brackish water (> 1 ppt). In the present study, we tested the hypothesis that differences in rearing environment (fresh or brackish water) results in ...

Abstract:
... Unprecedented threats to natural ecosystems mean that accurate quantification of biodiversity is a priority, particularly in the tropics which are underrepresented in monitoring schemes. Data from a freshwater fish assemblage in Trinidad were used to evaluate the effectiveness of hand-seining as a survey method in tropical streams. We uncovered large differences in species detectability when hand- ...

Abstract:
... We studied the reproductive biology of Astyanax lacustris in the southern Pantanal, Brazil. A total of 382 fish were analyzed from February 2009 to January 2011. The sex ratio differed significantly from 1:1, with a larger proportion of females (χ² = 27.24; p < 0.001). Females achieve higher standard length than males (mean 72.30 mm and 56.51 mm, respectively), and possess negative allometric grow ...

Anguilla anguilla; Anguilla rostrata; adults; bioassays; eel; experimental design; fisheries; freshwater; managers; migratory behavior; odors; spawning; survival rate; turbines
Abstract:
... American Eel Anguilla rostrata abundance has declined in recent decades, in part because sexually maturing, silver-stage adults, outmigrating from freshwater to oceanic spawning grounds, encounter migratory blockades or perish when passing through active hydroelectric turbines. To help improve downstream passage effectiveness and increase survival rates, the role of silver-stage American Eel consp ...

Abstract:
... Reproduction and maturation in the economically important, but data-deficient, Mustelus minicanis and M. norrisi were analysed using catches of populations exploited by a gillnet fishery during two years in the southern Caribbean Sea. In total, 691 female (mean ± SD total length–TL of 55.3 ± 5.8 cm) and 503 male (50.4 ± 4.9 cm TL) M. minicanis were assessed, with ~95% of all specimens deemed matur ...

Abstract:
... Stocking of hatchery-reared juvenile Atlantic Salmon Salmo salar is a common enhancement and recovery strategy across jurisdictions, yet its impact remains uncertain. We investigate the potential effectiveness of stocking in the Miramichi River system where approximately 150,000 first-feeding fry are stocked annually in reaches where wild juveniles are present. Local site and landscape level chara ...

Abstract:
... In marine ecosystems, cleaning is a mutualistic relationship in which so-called cleaners remove ectoparasites, diseased tissue, or mucus from the body of their clients, and thus help to maintain a healthy reef community. In spite of its importance in many marine habitats, this interaction remains poorly understood, particularly at oceanic islands. Here, we present the first comprehensive study of ...

Abstract:
... Diploids and tetraploids of the cyprinid loach Misgurnus anguillicaudatus coexist in many natural habitats in Asia. However, little is known about the biological and ecological differences between these two ploidy forms. We examined age, body size and growth rates of fish in a mixed ploidy population of M. anguillicaudatus in the Yangtze River basin in China. The sex ratios of both diploid and tet ...

Environmental factors, such as local physico-chemical water parameters, habitat-structural conditions, geography and human disturbances can have a profound impact on the structure and composition of biotic communities. This study investigates the relationship of these factors with fish diversity in medium to small streams in Central India and identifies the key determinants of species richness and ...

Abstract:
... Considering the homogeneity of marine environment, temperature might be a main environmental factor responsible for local adaptation across a wide latitudinal range. We reconstructed population structure and performed selection tests on a fragment of 1821 bp of the mitochondrial ATPase 6 (ATP6) and cytochrome b (CYTB) genes of Sebastiscus marmoratus sampled from five populations throughout the nor ...
