Multiple studies have shown that overfished ichthyofauna can grow in size, abundance, and reproductive output in no-take Marine Protected Areas (MPAs).
Other than physical changes to lotic habitat, the introduction of nonindigenous species from various stocking practices have also led to negative consequences for native ichthyofauna in Iowa (Bernstein and Olson, 2001).
The species is common on the Brazilian coast (Menezes & Figueiredo, 1980), and is one of the most numerous species in the Southern coast ichthyofauna of Parana in Southern Brazil (Chaves, 1998).
A noticeable feature of the ichthyofauna of the Near East is the relative high degree of conservatism of external morphology in spite of substantial genetic divergence.
This fact probably explains the difference of the surf zone ichthyofauna observed in the southeast and southern Brazilian coast compared to the northeast, which has tropical characteristics.
In the Northeast Pacific Ocean, numerous studies have investigated the ichthyofauna of bays and estuaries (Allen and Horn 1975; Horn and Allen 1976; Gotshall and others 1980; Horn 1980; Bayer 1981; Allen 1982; De Ben and others 1990; Allen and Herbinson 1991; Yoklavich and others 1991; Chamberlain and Barnhart 1993; Miller and Shanks 2005).
Recent studies of the ichthyofauna and other fossils (conodonts, miospores) in the Baltic area and Belarus show some controversy concerning the position of the Emsian/Eifelian boundary.
Although all fish larvae were collected from a single station, Alabama has a relatively short coastline (<85 km), thus the larval fishes collected likely represent the ichthyofauna of the entire Alabama inner shelf region.
Discovery of three species previously unknown from the Strawberry River system brings its total ichthyofauna to 110 species, a rich complement of species relative to river systems of comparable size in North America (Robison and Beadles, 1974; Robison, 1978).
Preliminary data on the ichthyofauna of the Gibraleon Clay Formation, Huelva, SW Spain]
In this book, Schwarzhans describes a new otolith-based marine ichthyofauna from a mid-Palaeocene (roughly 60 million years old) site in Greenland.
