Avances en el estudio reproductivo de la reineta (Brama australis) en la costa central de Chile [PDF]

open access: yesLatin American Journal of Aquatic Research, 2017
RESUMEN La información sobre los rasgos reproductivos de Brama australis, es escasa o no ha sido actualizada. Mediante análisis histológico, se estudió el tipo de reproducción, la madurez en longitud y las diferentes fases de desarrollo gonadal de machos y hembras. Se analizaron ejemplares capturados en la zona costera de Chile central.

Brama australis gel obtention and rheological characterization

open access: yesProcedia Food Science, 2011
AbstractGelatine from marine sources has been looked upon as a possible alternative to bovine and porcine gelatine. Common problems connected with fish gelatine from cold water species, such as those from Chilean coast, are low gelling and melting temperature and low gel modulus.

A mesocosm experiment investigating the effects of substratum quality and wave exposure on the survival of fish eggs [PDF]

open access: yes, 2010
In a mesocosm experiment, the attachment of bream (Abramis brama) eggs to spawning substrata with and without periphytic biofilm coverage and their subsequent survival with and without low-intensity wave exposure were investigated.

Environmental determinism of year to year recruitment variability of European eel in a small coastal catchment, the Frémur river, north-west France [PDF]

open access: yes, 2009
The influence of environmental factors (mainly the river flow) on the year-to-year variability of European eel Anguilla anguilla fluvial recruitment in a small coastal River (north-west France) was examined.

Recovery of the crucian carp Carassius carassius (L.): Approach and early results of an English conservation project

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 30, Issue 12, Page 2240-2253, December 2020., 2020
Abstract The crucian carp Carassius carassius, a cyprinid fish characteristic of small ponds, is in decline throughout most of its European range, including in England where it is currently thought to be non‐native. The present study, undertaken by the Norfolk Crucian Project, reports on reductions in pond populations of crucian carp in Norfolk ...

Changes in diet and trophic position of a top predator 10 years after a mass mortality of a key prey [PDF]

open access: yes, 2012
After the disappearance of primary prey, seabirds exhibit gradually decreased breeding performance, and eventually the population size drops. Results are presented of an investigation into the diet of little penguins (Eudyptula minor) at Phillip Island ...

A New Zealand demersal fish classification using Gradient Forest models

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 54, Issue 1, Page 60-85, March 2020., 2020
ABSTRACT Spatial classifications of the environment have previously been used to characterise biodiversity and to facilitate management planning at large spatial scales. Such classifications are more likely to be adopted if they can demonstrate integration of real patterns in habitats or biotic assemblages, in addition to environment.

Talla de madurez y época de desove de la reineta (Brama australis Valenciennes, 1836) en la costa central de Chile [PDF]

open access: yesInvestigaciones marinas, 2003
Landings of Pacific pomfret (Brama australis) is acquiring an increasing importance to the Chilean artisanal fishery. However, lack of information regarding its basic biology, in particular, reproductive dynamics, still persists. In this work we determine the spawning season of B. australis in the central coast of Chile and the length of maturity (LM).

General features of the ecology and biogeography of Tasmanian subtidal rocky shore communities [PDF]

open access: yes, 1984
A number of subtidal benthic assemblages of plants and animals which commonly occur around the Tasmanian coast are described. These assemblages are incorporated into a general scheme which relates subtidal zonation patterns to wave exposure and depth ...

Silent invasion: Sinanodonta woodiana successfully reproduces and possibly endangers native mussels in the north of its invasive range in Europe

open access: yesInternational Review of Hydrobiology, Volume 104, Issue 5-6, Page 127-136, November 2019., 2019
Abstract The explosive global spread of Sinadonta woodiana, a large‐bodied unionid mussel of East Asian origin, potentially affects the functioning of freshwater habitats and threatens native mussels. Molecular data indicate that its invasion in Europe started with a single colonization event, followed by in situ adaptation.
