Trehalose in Extenders for Cryopreservation of Tambaqui (Colossoma Macropomum) Sperm

Cryoletters, 2022
BACKGROUND: 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 ...

Methods of cryopreservation of Tambaqui semen, Colossoma macropomum

Animal Reproduction Science, 2015
This study compared three different techniques for sperm cryopreservation of Tambaqui (Colossoma macropomum). Semen was diluted in Beltsville Thawing Solution with the addition of dimethyl sulfoxide (DMSO) at various concentrations (5%, 10%, 15% and 20%).

The physiology of the Tambaqui (Colossoma macropomum) at pH 8.0

Journal of Comparative Physiology B, 2017
The 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.

Physiological and metabolic responses in juvenile Colossoma macropomum exposed to hypoxia

Fish Physiology and Biochemistry, 2020
This 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

Non-lethal molecular diagnostic for acanthocephalosis in Colossoma macropomum

Aquaculture, 2020
Abstract 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 ...

Use of cryotubes for the cryopreservation of tambaqui fish semen (Colossoma macropomum)

Cryobiology, 2015
Tambaqui (Colossoma macropomum) is a freshwater fish of great importance to aquaculture in several South American countries. Recent studies have developed a protocol for semen cryopreservation in 0.25 and 0.5 mL straws; however, this technique has limitations for fingerling production at a large scale due to the high fecundity of tambaqui.

Hormonal induction and semen characteristics of tambaqui Colossoma macropomum

Zygote, 2011
SummaryIn 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 ...

Paraquat and temperature affect nonspecific immune response of Colossoma macropomum

Environmental Toxicology and Pharmacology, 2009
This 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).

Isolation and characterization of a germ cell marker in teleost fish Colossoma macropomum

Gene, 2019
The native Amazonian fish tambaqui (Colossoma macropomum) is the second-largest scaled fish in South America and the most common native species in Brazil. To preserve genetic resources with sufficient genetic diversity through germ cell cryopreservation and transplantation techniques, a molecular marker for identifying the cells is required to trace ...
