Growing in the Dark Warmth: The Case of Amazonian Fish Colossoma macropomum [PDF]

Frontiers in Marine Science, 2018
Photoperiod is considered an important synchronizer of biological activities and endocrine pathways, including growth. As ectotherms, fish have many physiological functions controlled by the photoperiod. However, the combined effects of photoperiod and temperature should be clarified, particularly for tropical fish living near their upper thermal limit,

Estimation of genetic parameters for weight and length gains in tambaqui (Colossoma macropomum)

Brazilian Journal of Biology, 2023
Abstract The goal of this study was to determine the genetic parameters for growth traits in tambaqui (Colossoma macropomum) fish of similar age and weight. The data set included monthly measurements of body weight and length from120 fish for a year (1,440 measurements). The study found that weight gain had a heritability estimate of 0.01, while length

Eight basic principles for the elaboration of public policies and development projects for the Pantanal

Conservation Science and Practice, EarlyView.
The Pantanal is facing the challenge of preparing public policies at federal and state levels, but there is the need of a conceptual basis to support this process. This article prepared a list of eight main principles to be considered by legislators and decision‐makers, aiming to ensure proper protection and management strategies provided by the public

The effect of environmental factors on transepithelial potential in a model Amazonian teleost, the tambaqui (Colossoma macropomum): Implications for sodium balance in harsh environments

Journal of Fish Biology, EarlyView.
Abstract The tambaqui (Colossoma macropomum, G. Cuvier 1818) thrives both in the ion‐poor waters of the Amazon and in commercial aquaculture. In both, environmental conditions can be harsh due to low ion levels, occasional high salt challenges (in aquaculture), low pH, extreme PO2 levels (hypoxia and hyperoxia), high PCO2 levels (hypercapnia), high ...

Nitrogen excretion and oxygen consumption under severe hypoxia in siluriform fishes from the Amazon

Journal of Fish Biology, EarlyView.
Abstract Siluriform fishes collected from the Rio Negro and Rio Solimões proved to be highly resistant to aquatic hypoxia. In all four species analysed in this study, aquatic oxygen consumption significantly decreased from normoxic levels at water PO2 values near 1 kPa. Air‐breathing activity was observed only in Sturisoma sp. (Rio Negro).

Molecular characterization of Serrasalmidae hybrid in the upper Paraná River floodplain using molecular markers

Journal of Fish Biology, EarlyView.
Abstract This study reports the molecular identification of a tambacu—a hybrid of Colossoma macropomum and Piaractus mesopotamicus—in the floodplain of the upper Paraná River using molecular markers. The PCR‐GEL method, based on the analysis of COI and TROP fragments, successfully characterized the hybrid, while PCR‐SEQ, employing RAG2 and TROP markers,

Treatments for the control of Neoechinorhynchus buttnerae (Acanthocephala) in tambaqui Colossoma macropomum

Aquaculture International, 2022
Abstract Intensive fish farming with inadequate management can imbalance the fish-pathogen-environment relationship, culminating in diseases outbreaks. In the case of tambaqui Colossoma macropomum farming, it may be affected by acanthocephalosis, a parasitic infection without a specific and safe treatment yet. The objective of this study was to
