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 ...

Use of cryotubes for the cryopreservation of tambaqui fish semen (Colossoma macropomum)
Cryobiology, 2015Tambaqui (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, 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 ...

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).

Isolation and characterization of a germ cell marker in teleost fish Colossoma macropomum
Gene, 2019The 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 ...

Performance of the amazonian tambaqui, Colossoma macropomum, in pond polyculture
Aquacultural Engineering, 1993Abstract Tambaqui (48%) was reared in polyculture with grass carp (27%) and curimbata (25%) from 75 g mean weight for a period of 164 days. Ponds of 1200 m2 were stocked at a total density of 12720 ha−1. Fish were fed with an experimental diet made from soybean and maize at a daily rate calculated as 3% of the tambaqui biomass.

Ovopel and carp pituitary extract for the reproductive induction of Colossoma macropomum males
Theriogenology, 2017The objective of this study was to evaluate Ovopel and carp pituitary extract (CPE) in the reproductive induction of Colossoma macropomum males. Nine treatments were tested in triplicate, totaling 27 experimental units. C. macropomum breeders were subjected to the following treatments: 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, and 0.7 Ovopel pellet/kg; 2.5 mg CPE ...

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
