his study evaluated the utility of color pattern as a tool for sex identification inbroodstocks of Arapaima gigas. To do so, 110 individuals from three study sites had their sexdetermined with vitellogenin (VTG). Then, presence of red pigmentation was systematicallyevaluated scoring from the head (0) counting scales from the base of pectoral fin towards fishtail (1, 2, 3,...). Sex and study site were the variables that had significant effects on the zero-inflated negative binomial model (p<0.01) to assess color pattern. Discriminant functionanalysis (DFA) yielded 82 % of correct classification for females and 76 % for males. With suchmethod, both sexes could be identified with similar hit rates. Differences were seen in sexualcolor pattern comparing the different study sites. Therefore, application of the method should berestricted to site-specific broodstocks rather than be a general rule for all populations. Inconclusion, sex identification in Arapaima broodstocks through color pattern may be considereda cheap alternative for broodstock management but should be used in combination with otheravailable methods to yield optimal rates for sex identification (i.e. endoscopy, cannulationand/or vitellogenin). |

The by-products generated from industrial filleting of tilapia surimi can be used for the manufacture of surimi. The surimi production uses large amounts of water, which generates a wastewater rich in organic compounds (lipids, soluble proteins and blood). Optimizing the number of washing cycles will contribute to a more sustainable production. A mathematical model of mechanically recovered tilapia meat (Oreochromis niloticus) for the processing of surimi (minced fish washing cycles and tapioca starch addition) based on two quality parameters (texture and moisture) was constructed by applying the response surface methodology (RSM). Each factor had an important effect on the moisture and texture of surimi. This study found that the optimal formulation for producing the best surimi using the by-products of tilapia filleting in manufacturing fish burger were the addition of 10% tapioca starch and three minced fish washing cycles. A microstructural evaluation supported the findings of the mathematical model. |
