Trehalose in Extenders for Cryopreservation of Tambaqui (Colossoma Macropomum) Sperm
Cryoletters, 2022BACKGROUND: Sugars may act as either energy substrates or non-penetrating cryoprotectants. OBJECTIVE: Inclusion of non-penetrating trehalose was tested in extenders for the cryopreservation of Tambaqui ( Colossoma macropomum) sperm. MATERIALS AND METHODS: Sperm was extended 1/9 (v/v) in Beltsville Thawing Solution (BTS) with 10% DMSO (control) or 50 ...

Non-lethal molecular diagnostic for acanthocephalosis in Colossoma macropomum
Aquaculture, 2020Abstract The tambaqui C. macropomum is intensively produced in aquaculture and is subject to numerous parasitosis, such as acanthocephalosis, a parasitosis caused by Neoechinorhynchus buttnerae infection. The conventional diagnosis of acanthocephalosis is performed through fish euthanasia, which brings economic loss for fish farmers and poor ...

The physiology of the Tambaqui (Colossoma macropomum) at pH 8.0
Journal of Comparative Physiology B, 2017The Tambaqui is a model neotropical teleost which is of great economic and cultural importance in artisanal fisheries and commercial aquaculture. It thrives in ion-poor, often acidic Amazonian waters and exhibits excellent regulation of physiology down to water pH 4.0.

Paraquat and temperature affect nonspecific immune response of Colossoma macropomum
Environmental Toxicology and Pharmacology, 2009This study evaluated the effect of paraquat (PQ) and temperature on hematological parameters and nonspecific immune system of fish Colossoma macropomum (Cachama). Juveniles were used for all experiments. Fish were exposed to three temperatures (18, 28, 35°C) and 10mg/L PQ during 21 days (PQ LC(50) 96h was of 48.05mg/L).

Tambaqui females (Colossoma macropomum) spawn after hormonal induction with buserelin acetate
Animal Reproduction Science, 2020The aim of this study was to evaluate induced reproduction in tambaqui females using buserelin acetate as compared with the traditional treatment regimen with carp pituitary extract (CPE). Reproductive traits of females with a body weight (BW) of 8.47 ± 1.52 kg were evaluated in ten females treated with buserelin acetate at the dose of 0.5 mL/kg BW, in

Hormonal induction and semen characteristics of tambaqui Colossoma macropomum
Zygote, 2011SummaryIn the hatchery-bred tambaqui Colossoma macropomum, spontaneous semen release does not occur, and hand-stripping produces reduced semen volume. The goal of this work is to evaluate the effects of hormonal induction with carp pituitary extract (CPE) on both qualitative (visual aspect, pH, motility, viability and morphological abnormalities) and ...

Physiological and metabolic responses in juvenile Colossoma macropomum exposed to hypoxia
Fish Physiology and Biochemistry, 2020This study aimed to evaluate hematological, biochemical, and gasometric parameters of tambaqui juveniles (Colossoma macropomum) exposed to hypoxia and subsequent recovery. Six animals were subjected to normoxia (basal) treatment with dissolved oxygen (DO) 6.27 ± 0.42 mg L-1. Water flow and aeration were reduced for 3 days (hypoxia), during which DO was

The complete mitochondrial genome sequence of Colossoma macropomum (Characiformes: Serrasalmidae)
Mitochondrial DNA Part A, 2015Colossoma macropomum (Cuvier, 1816) is the largest characin of South America. This species and its congeners mainly feed on zooplankton, insects, snails and decaying plants. In this paper, we sequenced and annotated the complete mitogenome of C. macropomum. The total length is 16,703 bp, and it typically consist of 37 genes, including 13 protein-coding

Currently, great importance has been given to the study of external morphology, especially in fish, when it is used as a means of identifying hybrids. This paper considers a multiple logistic regression model based on the truss protocol to compare morphological covariation patterns between specimens of C. macropomum and the hybrid C. macropomum (♀) x P.
