1. Hatchability of gemmules of two Neotropical freshwater sponges (Porifera: Spongillida)
RESUMO Ambientes de águas continentais estão suscetíveis a condições ambientais extremas, determinantes à evolução de várias estratégias adaptativas para estas condições variáveis. As esponjas de águas continentais produzem corpos resistentes chamados gêmulas, que contêm células totipotentes e espículas especializadas (gemoscleras). As gêm

2. Upstream dam impacts on gilded catfish Brachyplatystoma rousseauxii (Siluriformes: Pimelodidae) in the Bolivian Amazon
ABSTRACT This paper explores the effects of two run-of-river dams (Jirau and Santo Antônio) built in cascade in the middle Madeira River (Brazil) on the interruption of long-distance migration routes of the gilded catfish (Brachyplatystoma rousseauxii). A participative monitoring system was set up to compare capture by commercial fishers approximately 1500

4. Cooling of curimba (Prochilodus lineatus) embryos using different concentrations of dimethyl sulphoxide and methanol
ABSTRACT This study aimed to evaluate the effect of using different concentrations (5, 7.5, 10, and 12.5%) of two permeating cryoprotectants, dimethyl sulphoxide (DMSO) and methanol, on Prochilodus lineatus embryos while being subjected to cooling for 2, 4, 6, and 8 h at 4 °C. We analyzed the hatching rate, viable larvae, and counts of hatched and spoiled e

5. Phospholipid composition and resistance to vitrification of in vivo blastocyst of a Brazilian naturalized porcine breed
RESUMO Blastocistos de suínos foram submetidos ao MALDI-TOF para se identificarem os principais fosfolipídios (PL). Depois, parte destes embriões (D6) foram vitrificados (n=52), ou permaneceram frescos (grupo controle, n=42). Após o aquecimento, os blastocistos foram cultivados in vitro para se avaliar a reexpansão e a eclosão (BE) às 24 e 48 horas. F

6. Oxidative Stress of in-Ovo Ochratoxin A Administered during Chick Embryonic Development
ABSTRACT The present work was carried out to study the effect of in-ovo injection of ochratoxin A (OTA) as an oxidative stress and its consequences on hepatic and kidney functions, thyroid activity, and histological examination of brain and liver in chicken embryos and subsequently in the hatching chicks. On the 10th day of incubation, one hundred and sixty-

8. Influence of dietary 1αlpha-hydroxycholecalciferol, individually or in combination with microbial phytase in calcium and phosphorus deficient diets on growth performance and tibia parameter of Japanese quails (Coturnix japonica)
ABSTRACT. The effect of 1α-OH-D3 in calcium-phosphorus (Ca-P) deficient diets on Japanese quail growth performance and tibia parameters was investigated. Eight-day-old (n = 160) newly hatched quails were weighed and randomly allocated to 20 groups, each with 4 replicate pens of 8 birds. Treatments were as follows: T1, Ca-P-adequate; T2, Ca-P-deficient; T3,

9. Maintenance of Octopus vulgaris Type II paralarvae in an estuarine area
ABSTRACT We assessed the survival of paralarvae kept in a floating wooden box attached to an oyster extensive cultivation system with no extra food supply. A total of 7700 newly hatched paralarvae were maintained in a 10.5-L floating box (7 cm height × 30 cm width × 50 cm length) covered with a 180-μm mesh net for 14 days with no extra food supply.

10. Effects of in ovo injection of lysine and methionine into fertile broiler (parent stock) eggs on hatchability, growth performance, caecum microbiota, and ileum histomorphology
ABSTRACT We investigated the effect of in ovo injection of lysine, methionine, or their mixture into fertile broiler eggs on hatchability, chick weight, growth performance, inner organ development, caecum total aerobic bacteria, E. coli, coliforms, Enterobactericaea, and ileal histomorphology of broilers. Three hundred fertile eggs obtained from 60-week-old

11. Asynchronous Hatching and Extended Parental Care in Aegla schmitti (Decapoda, Anomura)
ABSTRACT The aim of this study was to describe the behavior of newly-hatched juveniles and maternal care in Aegla schmitti. The experiment was conducted using seven ovigerous females with eggs at different stages of embryonic development and 12 eggs that had been placed in a separate aquarium. We observed asynchronous hatching in all females, with a mean of

12. Effect of Hatching Time on Yolk Sac Percentage and Broiler Live Performance
ABSTRACT This study investigated the effects of broiler chick hatching time on the percentage of the yolk sac and subsequent broiler live performance. Broiler hatching eggs were obtained from a commercial flock at 55 wk of age and were stored for 2 d at 18°C and 75% relative humidity (RH) prior to incubation. Chicks were identified as hatching Early (471-47
