Migratory Fishes of South America

2004
Fish species that migrate within the great rivers of South America support important local fisheries but are little known outside their native range. This book, written specially for the World Bank and the International Development Research Centre, represents the first collection of the work of local scientific experts on these remarkable fish.

Freshwater to Seawater Transitions in Migratory Fishes

2012
The transition from freshwater to seawater is integral to the life history of many fishes. Diverse migratory fishes express anadromous, catadromous, and amphidromous life histories, while others make incomplete transits between freshwater and seawater.

PARASITE GENOTYPES IDENTIFY SOURCE POPULATIONS OF MIGRATORY FISH MORE ACCURATELY THAN FISH GENOTYPES

Ecology, 2006
DNA-based assignment of individuals to their population of origin has many applications such as mixed-stock analysis, identifying individuals from protected populations, and elucidating migration patterns. However, low genetic differentiation among populations will cause misassignments.

Dams crossing by migratory fishes

1992
In order to allow the migration of fishes in rivers with dams, fish passes have been installed. The first results from these installations have led to some progress in the dimensioning technique and in the choice of the system type depending on the species.

Cryopreservation of sperm in Brazilian migratory fish conservation

Journal of Fish Biology, 2003
Simple, effective protocols for cryopreserving milt of five Brazilian migratory characids (Brycon orbignyanus, Prochilodus lineatus, Piaractus mesopotamicus, Salminus maxillosus and Leporinus elongatus) and one Brazilian migratory catfish (Pseudoplatystoma corruscans) are described.

Dams and migratory fishes

1993
Passes à poissons, écluses, ascenseurs ou prébarrages : les solutions se multiplient, qui, d'aval en amont permettent aux poissons migrateurs de se jouer des obstacles qui ponctuent nos rivières. Reste à intensifier ces efforts. Reste, aussi, d'amont en aval, à trouver la réponse ad hoc aux problèmes de dévalaison.

Transport of Seaweeds by Tagged Migratory Fish Populations

Botanica Marina, 1992
A striped bass (Roccus saxatilis) that was tagged and released from the Potomac River, Maryland (Chesapeake Bay) was caught within the Great Bay Estuary System (New Hampshire/Maine). It bore a plastic identification tag densely clothed with 12 macroalgae, including 1 species of colonial diatom, 5 green and 6 red algal species.

An Introduction to Modeling Migratory Behavior of Fishes

1984
This paper reviews models of basic fish movement patterns and their incorporation into models of fish migration. Computer simulations of various types of kineses and taxes have led researchers to the conclusion that only certain types of turning response are capable of producing directed movement of organisms.
