Effect of dichlorvos on the acetylcholinesterase from tambaqui (Colossoma macropomum) brain.
Dichlorvos is an acutely toxic organophosphorous pesticide that is known as a classical acetylcholinesterase (AChE; EC 3.1.1.7) inhibitor. Here, the brain AChE from the important Amazonian fish tambaqui (Colossoma macropomum) was assayed in the presence of this insecticide and also of deltamethrin, a classical sodium and potassium channel inhibitor (negative control). Four tissue homogenates we...
متن کاملOocyte quality of tambaqui (Colossoma macropomum) during the reproductive season.

متن کاملTransportation of juvenile tambaqui (Colossoma macropomum) in a closed system.
The objective of this study was to investigate the effect of density, duration and the use of additives to the water during the transportation of juvenile tambaqui (Colossoma macropomum) and use of this data to establish a safe transportation protocol for the species. The tested products and dosages were: salt (1000, 2000 and 3000 mg/L), gypsum (100, 300 and 500 mg/L) and benzocaine (10, 20 and...
متن کاملEffects of afferent input on the breathing pattern continuum in the tambaqui (Colossoma macropomum).
This study used a decerebrate and artificially-ventilated preparation to examine the roles of various afferent inputs in breathing pattern formation in the tambaqui (Colossoma macropomum). Three general breathing patterns were observed: (1) regular breathing; (2) frequency cycling and (3) episodic breathing. Under normoxic, normocapnic conditions, 50% of control fish exhibited regular continuou...
متن کاملDNA Isolation from Fresh and Cryopreserved Semen of Tambaqui (Colossoma macropomum)
Semen cryopreservation is an import toll for reproductive management of fish species, which increasingly it is applied in the commercial production of fish. Cryopreservation need of the cryoprotectors agents (CPAs) that may be a complication factor in DNA extraction that can affect the quality of isolated DNA. Genomic DNA constitutes the total genetic information of an organism and it is used f...
