1. Genetic Variability of Brycon hilarii in a Repopulation Program
ABSTRACT Brycon hilarii, popularly called piraputanga in Brazil, is a species distributed throughout the whole basin of the river Paraguay. In recent years, the species has been on a repopulation program due to its remarkable decline as a wild species in the region. Assessment of the genetic diversity of broodstock and fingerling stocks in repopulation progr

2. Essential oils in the initial phase of broodstock diets of Nile tilapia
This study evaluated the effect of feed supplementation (at doses of 0, 50, 100, 150, and 200 mg/kg) with SALUTO®, a microencapsulated blend of essential oils including carvacrol, cinnamaldehyde, 1,8-cineol, and pepper oleoresin, in Nile tilapia (Oreochromis niloticus) broodstock on reproductive and growth parameters during the initial phase of rearing.

3. Growth of Nile tilapia post-larvae from broodstock fed diet with different levels of digestible protein and digestible energy
This study was carried out to evaluate the influence of different levels of digestible energy and digestible protein in diets of Nile tilapia (Oreochromis niloticus) broodstock on offspring growth during sex reversal stage. A total of 2,700 post-larvae (8.2±0.001 mg) derived from breeders fed nine diets with distinct levels of digestible protein (28, 34 and

4. RelaÃÃo entre energia e proteÃna digestÃveis para matrizes de tilÃpia do Nilo (Oreochromis niloticus) / Digestible energy and protein ratio to Nile tilape female (Oreochromis niloticus)
O trabalho visou analisar o efeito entre os diferentes nÃveis de proteÃna (PD) e energia digestÃveis (ED) sobre o crescimento, desempenho reprodutivo e qualidade da prole de fÃmeas de tilÃpia do Nilo (Oreochromis niloticus). Foram avaliadas nove raÃÃes a partir da combinaÃÃo entre trÃs nÃveis de PD (28, 34 e 40%) e trÃs nÃveis de ED (2.800, 3.40

5. Genetic diversity of piracanjuba used in stock enhancement programs with microsatellite markers
The objective of this work was to estimate the genetic diversity of a Brycon orbignyanus lot used in stock enhancement programs, using microsatellite markers. Samples of 44 broodstocks, 70 larvae and 69 fingerlings, were analyzed with amplification of five loci described for Brycon opalinus. The number of alleles, the observed (Ho) and expected (He) heterozy

6. Técnica simples de marcação externa de reprodutores de tilápia nilótica (Oreochromis niloticus) / Simple tecnique for external marking of nile tilapia’s broodstock (Oreochromis niloticus)
Com a finalidade de organizar um programa de controle da reprodução de tilápia nilótica (Oreochromis niloticus) em laboratório, foi desenvolvida uma técnica na qual foi utilizada pérolas de cerâmica presas à musculatura dorsal do animal por transfixação com um fio sintético flexível. Foram usados 60 peixes com peso médio de 12g e 60 com peso m�

7. REPRODUCTIVE RESPONSE OF FEMALE OF BLACK CATFISH Rhamdia quelen, FEED WITH DIFFERENTS PROTEIN AND LIPIDS SOURCES / RESPOSTAS REPRODUTIVAS DE FÊMEAS DE JUNDIÁ (Rhamdia quelen) ALIMENTADAS COM DIFERENTES FONTES PROTÉICAS E LIPÍDICAS
The aim of the work was to evaluate the effect of different protein and lipid sources of animal and vegetable origin on the reproductive performance of black catfish Rhamdia quelen females. Three experiments were accomplished with duration of 90 days each, divided in three phases: Phase I, Reproducers feeding; phase II, Induced reproduction and eggs and larv

8. AVALIAÇÃO DO USO DE SUBSTRATO DE AREIA EM TANQUES DE MATURAÇÃO DO CAMARÃO-ROSA Farfantepenaeus paulensis (Pérez-Farfante,1967).
Under laboratory conditions, broodstock of penaeid shrimp are usually maintained in hard-bottom tanks (concrete or fiberglass). This practice, however, may affect the reproductive performance of Farfantepenaeus paulensis as this species has a strong burrowing behavior. With this in mind, wild-caught broodstock maintained for 50 days either in hard-bottom mat

10. Fluorescent amplified fragment length polymorphism (fAFLP) analyses and genetic diversity in Litopenaeus vannamei (Penaeidae)
The Pacific white shrimp, Litopenaeus vannamei (Penaeidae), represents about 95% of all Brazilian shrimp production. The Brazilian L. vannamei foundation broodstock was made up of specimens collected from different American Pacific sites, but little information was collected on the genetic structure of the broodstock. We used the fluorescence amplified fragm

11. Restriction site heteroplasmy in the mitochondrial DNA of Brycon opalinus (Cuvier, 1819) (Characiformes, Characidae, Bryconiae)
Homoplasmy is a feature usually found in the mtDNA of higher animal taxa. On the other hand, the presence of two classes of mtDNA in the same cell or organism is rare and may appear in length or site variation. Data from mtDNA RFLP analysis of Brycon opalinus populations (Cuvier, 1819; Characiformes, Characidae, Bryconinae) revealed site heteroplasmy from en
