| A feeding trial was conducted to evaluate the effect of the supplementation of hydrolysates from tuna head on the survival and growth of Penaeus vannamei. To this end, a feeding trial was performed on eleven groups of shrimps of average weight 4.34 g. Every group was distributed into three tanks (30 shrimps per tank of 150 L) and was fed with one of the following eleven diets, all of them containing 40% crude protein: one diet containing tuna head meal as the principal protein source, which was used as control diet; nine diets formulated by replacing 50% tuna head meal by fish protein hydrolysates (FPH), and finally one commercial diet chosen as a reference. FPH were obtained by hydrolysis of tuna head during 2, 3 or 6 h and ulterior centrifugation in order... |

| This research presents a detailed study of the morphology of the head of adult in both sexes of the south Brazilian species of the Morphinae subfamily (Lepidoptera, Nymphalidae), as mentioned below: Morpho helenor violaceus Fruhstorfer, 1912; Iphimedeia hercules (Dalman, 1823); Iphixibia anaxibia (Esper, 1801); Cytheritis portis thamyris (Felder & Felder, 1867); Cytheritis aega (Huebner, 1822); Pessonia catenaria (Perry, 1811); Grasseia menelaus nestira (Huebner, 1821). |

| A detailed study of the morphology of the head of Thyridia psidii cetoides (Rosenberg & Talbot, 1914) (Nymphalidae, Ithomiinae) adults from both sexes is presented. The material was obtained at the city's plant nursery "Horto Florestal de Curitiba", Paraná, Brazil; mainly by rearing eggs and larvae collected there on Cyphomandra betacea (Canavilles) Sendtner, 1845 (Solanaceae). When possible, all the results obtained were compared with those already available in the literature concerning external morphology studies pertinent to other Nymphalidae subfamilies (Brassolinae, Morphinae and Danainae). |

| Genetic parameters of production traits (growth, carcass yield, fillet yield) and bony tissues (head and vertebral axis) were estimated for large all-female rainbow trout Oncorhynchus mykiss reared in freshwater. Genetic parameters were estimated using REML at 16 months of age (1636 g) on 1962 DNA-assigned progenies from a partial factorial mating design with 60 dams and 100 sex-reversed sires. Most traits presented medium to high heritability (0.37 to 0.54). A high genetic correlation (r(A)=0.97) was found between fillet yield and headless gutted carcass yield (or HGCarc%). Due to its higher heritability and high genetic correlation with fillet yield, selection on HGCarc% should result in a 50% increase in selection efficiency on fillet yield by reducing... |
