Hydroacoustical Survey of The Near Surface Distribution, Abundance and Biomass of Small Pelagic Fish in The Gulf of California
(Pacific Science, 2012)
Near-surface distribution (10 – 40 m depth), abundance, and biomass of small pelagic fish were estimated with an echo sounder (EY-60, 120 kHz) duringJanuary 2007 in central and northern areas of the Gulf of California. ...
The 'pole-hooking' method: A novel and economical technique for in situ tagging small to medium-sized fishes
(Elsevier Science, 2008-06)
We describe a new manual procedure for catching and tagging fish underwater, the 'pole-hooking' method, and demonstrate and discuss its advantages over standard tagging techniques (i.e. hook-and-line fishing). The new ...
Spatial distribution and species composition of small pelagic fishes in the Gulf of California
(Universidad de Costa Rica, 2008)
The fish fauna in the fish passage at the Ourinhos Dam, Paranapanema River
(SOC BRASILEIRA ICTIOLOGIASAO PAULO, 2012)
The composition and abundance of the fish assemblage were evaluated in the fish ladder of Ourinhos Dam, the newest dam (closed in 2005) in the cascade of dams constructed on the Paranapanema River. Samplings were carried ...
Predation on microcrustaceans in evidence: the role of chaoborid larvae and fish in two shallow and small Neotropical reservoirs
(Sociedade Brasileira de Carcinologia, 2012-07-01)
This study was focused on the predation upon microcrustaceans by an invertebrate predator (chaoborid larvae), and vertebrate predators (fish), in two small reservoirs in southeastern Brazil, with and without macrophytes, ...
Drifting in a free-flowing river: Distribution of fish eggs and larvae in a small tributary of a Neotropical reservoir
(Revista Biota Neotropica, 2021-01-01)
We investigated spatial and temporal variations in the distribution of fish eggs and larvae in the Guarei River, a free-flowing tributary located in the upper section of the Jurumirim Reservoir, Paranapanema River, Brazil. ...
Harvesting technology and catch-to-biomass dependence: The case of small pelagic fish
(Universidad Alberto Hurtado. Facultad de Economía y Negocios, 2015)
Dispersal of fish eggs and larvae in a cascade of small hydropower plants with fish ladders
(Springer, 2020-10-10)
This study was conducted to investigate fish eggs and larvae dispersal in a river stretch influenced by small hydropower plants in Southeast Brazil. The main hypothesis is that the downstream dispersal of free-flowing eggs ...
