“…Pedrazzani et al (2009) also found similar results when comparing the effect of two desensibility methods for Nile tilapia, wherein the rigor mortis has been reached between 8 and 9 hours after slaughter. Moreover, Batista et al (2004) and Almeida et al (2005) mentioned that when slaughtering specimens of matrinxã (Brycon cephalus) and tambaqui (Colossoma macropomum) respectively, rigor mortis was established much earlier, between 30 and 75 minutes. This suggests that the species respond differently on this parameter, which may be related among other factors to the slaughter method and the muscle fiber profile of each species.…”

The study was carried out with the objective of evaluating the influence of pre-slaughter stress on meat quality of Nile tilapia (O. niloticus) for 10 days of storage in ice. 75 whole fish were used eviscerated, with average weight and length of 825.75 ± 101.59 g and 28.25 ± 0.81 cm, respectively. The treatments consisted of time in which the animals underwent pre-slaughter hypoxia, being 0, 3 and 6 minutes. Rigor mortis and muscle pH were assessed besides the application of the Quality Index Method and analysis of total protein and blood glucose. Rigor mortis did not differ among treatments during the storage period, and after three hours all animals were in rigor stage. The muscle pH values varied widely during the study period, observing higher values on the third day of storage. Sensory analysis showed that after 10 days the tilapia from the different treatments did not differ in the evaluated quality parameters similarly, there was no difference regarding the evaluated blood biochemical parameters Thus, hypoxia of 6 minutes pre-slaughter does not influence the rigor mortis, muscle pH, qualitative perception of the meat quality, total protein and blood glucose of Nile tilapia.Keywords: hypoxia; pH; rigor mortis; quality index method; blood parameters.Practical Application: Study the effects of pre-slaughter stress on the Nile tilapia meat quality.

“…Evaluating tambaqui quality (Colossoma macropomum), sacrificed by asphyxiation and kept on ice, the stage of full rigor occurred 30 minutes after slaughter [14]. For matrinxãs (Brycon cephalus) slaughtered and kept on ice, the stage of full rigor occurred at 75 minutes after death [15].…”

Consumers rigorously assess the quality of fishing products, considering mainly freshness and appearance. The slaughter method is an important factor in relation to the freshness of the fish, because it maintains important organoleptic characteristics that will influence the marketing of these products, therefore, in this study an evaluation of the Rigor Index (RI%) of cobia was performed. The following methods were used: in desensitizing with eugenol and hypothermia. Immediately after the slaughter, the monitoring of rigor mortis began. In the method of slaughter with eugenol reached full rigor after 6 hours, and in the method by hypothermia lasted 4 hours. The slaughter method with lower stress showed a significant difference, with a positive influence on the duration of the stages of rigor mortis.Over time, the choice of slaughter methods is based almost exclusively on ease of application and those with the lowest cost, and not on those that cause less suffering Leandro Presenza et al.
