External Morphology of Leporinus oliveirai (Characiformes: Anostomidae) During Early Life Stages. [PDF]
J MorpholHerein, we describe the early development of Leporinus oliveirai, a recently described species, documenting its external morphology with photographs and illustrations. The ontogeny of L. oliveirai is compared with other anostomids and developmental patterns are described for the family.

Ontogeny of the Skeleton of Leporinus oliveirai (Characiformes, Anotomidae). [PDF]
J MorpholIn this study, we provide the first complete description of the skeleton ontogeny of an anostomid. The developmental sequence of 141 bony elements is described and illustrated. The main discoveries are numerous conical teeth on the premaxilla and dentary that are replaced with three or four large incisiform multicuspid teeth, that become unicuspid in ...

Dietary Protein Hydrolysate From <i>Calanus finmarchicus</i> Reduces Oxidative Stress and Increases Intestinal Health in European Sea Bass (<i>Dicentrarchus labrax</i>) Juveniles. [PDF]
Aquac NutrThe aquaculture industry is in dire need of novel feed ingredients that can improve the health and welfare of farmed fish and shrimp. Zooplankton are natural and underutilized marine resources with the potential to be part of a nutritional solution. The aim of this study was to determine the health effects for European sea bass juveniles fed diets with

Reviews in Aquaculture, Volume 15, Issue 2, Page 610-624, March 2023., 2023 Abstract After more than four decades of production in the European Union, turbot (Psetta maxima) farming is a mature sector with a moderate growth trend (2.74% in 2020). Although up to seven countries started the production of this species, there are only four producing countries in 2020, with more than 90% of the production concentrated in the ...

Journal of the World Aquaculture Society, Volume 53, Issue 5, Page 1031-1041, October 2022., 2022 Abstract For the evaluation of the effects of the transport density of pirarucu juveniles, 210 juvenile pirarucus, Arapaima gigas (488 ± 26.5 g) were randomly distributed in 12 plastic boxes at transport densities of 98, 146, 195, and 244 g L−1. The transport was carried out on a paved highway for 4 h, and at the end of the transport, all were returned

Journal of the World Aquaculture Society, Volume 53, Issue 2, Page 500-515, April 2022., 2022 Abstract We evaluated the possible interaction between feeding frequency (FF) and feeding rate (FR) on growth, nutrient utilization, body composition, and plasma metabolites of juvenile Nile tilapia, Oreochromis niloticus (6.57 g). We tested three FFs: two, four, and six times a day, and two FRs: apparent satiation (AS) or restricted regime (RR ...

Drought, fire and grazing precursors to large‐scale pine forest decline
Diversity and Distributions, Volume 27, Issue 7, Page 1138-1151, July 2021., 2021 Abstract Aim Temperate forests are currently facing multiple stresses due to climate change, biological invasions, habitat fragmentation and fire regime change. How these stressors interact with each other influences how, when and whether ecosystems recover, or whether they adapt or transition to a different ecological state. Because forest recovery or

Aggression supersedes individual oxygen demand to drive group air‐breathing in a social catfish
Journal of Animal Ecology, Volume 87, Issue 1, Page 223-234, January 2018., 2018 Here the authors show that, in groups of air‐breathing fish, influential individuals exert a powerful overriding effect on risk‐taking during synchronous air‐breathing by the entire group. This is an extraordinary example of how social context can obscure interactions between an individual's physiological and behavioural traits and risk‐taking to ...

Influência do pH sobre ovos e larvas de jundiá, Rhamdia quelen (Osteichthyes, Siluriformes)
Acta Scientiarum: Biological Sciences, 2008 A influência do pH sobre o desenvolvimento de ovos e larvas de jundiá (Rhamdia quelen, Quoy e Gaimard, 1824) foi avaliada utilizando-se experimentos inteiramente casualizados com 6 tratamentos (pH 4, 5, 6, 7, 8 e 9), em três desovas.
