ABSTRACT This study was conducted to investigate the effects of dietary propolis alcohol extract supplementation on growth performance, digestibility, intestinal morphometry, and physiologic parameters Nile tilápia (Oreochromis niloticus L.) juveniles. For performance experiment 120 fish averaging 1.41±0.3g were randomly distributed into 24 tanks (70L each) in a closed recirculation water system with constant aeration biofilter. The animals four treatments using completely randomized design...
Oreochromis niloticus (Nile tilapia) is one of the most produced fish for human consumption globally; however, these are susceptible to exposure toxic chemicals in water. Pyriproxyfen a pesticide widely used control mosquitoes drinking water supplies and pests crops. The present study aimed examine pyriproxyfen's effects on O. fingerlings exposed using an acute 96 h subchronic tests 28 days. lethal concentration LC50-96 was 2.77 mg L-1, no observed effect (NOEC), lowest (LOEC) 1.0 2.5...
Abstract This work describes the detailed ultrastructural morphology of phagocyte imprisoning an oyster Nematopsis (Apicomplexa) found in Crassostrea rhizophorae, city Maceió (AL), Brazil. The highly infected hosts had half-open leaflets with weak, slow retraction adductor muscles. Variable number ellipsoid oocytes, either isolated and or clustered, was between myofibrils muscle. Each oocyst incarcerated a parasitophorous vacuole host uninucleated phagocyte. oocysts were composed dense wall...
Eugerres brasilianus is an appreciated commercial species in the market of northeastern region Brazil.The purpose this study was to analyze and determine diet, reproductive period, management carapeba recirculating aquaculture systems.The fishes were caught with a gillnet at two different places near São Francisco River mouth.The stomach content analyzed according frequency occurrence method, using index relative importance, assessing degsubjectedree repletion.The period established by...
Devido as mudanças no baixo curso do rio São Francisco, o objetivo trabalho foi identificar os aspectos sociocultural da pesca artesanal e compreender a dinâmica das espécies de peixes na planície fluvial. O estudo realizado microrregião Penedo através entrevistas semiestruturadas. Os foram coletados durante maré vazante usando malhadeiras redes arrasto. levantamento ictiofauna fluvial identificando dominantes sua diversidade. Há uma dependência substancial famílias pescadores atividades...
The introduction of new fish species to the aquaculture industry is essential halt progressive decline natural stocks. sheepshead Archosargus probatocephalus a commercially valuable sparid with potential for breeding in captivity, but limited information regarding parasitic infections that could pose significant threat its sustainable production. Thus, present study aimed myxozoan diversity infecting A. probatocephalus. A novel Henneguya sp. was detected forming plasmodia gill lamellae...
A apicultura é uma atividade capaz de causar impactos positivos nos aspectos social, ambiental e econômico. No Nordeste brasileiro desenvolvida principalmente pela agricultura familiar, contribuindo para a renda das famílias permanência da população no campo, além preservar o bioma caatinga. Nesse contexto, objetivo desse trabalho foi avaliar impacto entre agricultores familiares do sertão Alagoas. Foram realizadas entrevistas semiestruturadas com familiares. produção mel iniciou Projeto...
O presente trabalho teve como finalidade a avaliação do comportamento social de Betta splendens submetidos ambientes com diferentes cores. A pesquisa duração 60 dias experimentação, onde foram utilizados 18 Bettas splendens, machos, distribuídos individualmente em aquários experimentais 1,5 L capacidade efetiva, sendo seis tratamentos, que as cores ambiente (aquário), constando de: T1 – cor branca, T2 verde, T3 azul, T4 vermelho, T5 amarela e T6 preta três repetições cada, um animal para...
The São Francisco River represents 2/3 of the Northeast Region freshwater availability.Its basin is divided into Upper Francisco, Middle Sub-Middle and Lower Francisco.The one most impacted regions Northeast, considering factors related to fishing, electric power generation city sewage pollution.The first Scientific Expedition aimed at evaluating water quality, pollution, silting, deforestation ciliary forest, socio-economic survey, environmental education, ictiofaunal composition, analysis...
A histopathological survey was conducted to investigate the presence of microparasites in fish Archosargus probatocephalus a river near Maceió, Brazil. Light microscope observations fragments gill showed small cysts containing numerous myxospores that were morphologically identified as Henneguya. Transmission electron microscopy further revealed several cells groups prokaryotic within large cytoplasmic vacuoles. Each infected host cell displayed single vacuole variable number Rickettsia-like...
The aim of this study was to evaluate the effects alimentary restriction on Betta splendens performance. For experiment, 24 males were used, with initial average weight 0.55 ±0.06 grams, distributed in experimental aquaria 1.5 liters water without aeration a completely randomized design, four treatments and six repetitions. were: T1 – daily fed animals (control), T2 - for days one day (6A/1R), T3 five two (5A/2R) T4 three (4A/3R). fishes twice at 08:00am 4:00pm. variables studied final (FW),...
The Eugerres brasilianus is a commercial species appreciated in markets the Northeastern region of Brazil . This study had as objective to evaluate and get know feed diet, reproductive period management carapeba fish tanks recirculation system for intensive raising. were caught with gill net at two different places near mouth Sao Francisco River. stomach content was analyzed according occurrence frequency method, applying on it Important Index relative food, evaluating calculating degree...
RESUMO O objetivo do presente estudo foi avaliar o desempenho zootécnico, os parâmetrosmorfométricos, comportamento social, a viabilidade econômica e análise microbiológica da água de cultivo tecidos corpóreos Betta splendens alimentados com folha amendoeira Terminalia catappa (FFDA) como aditivo.

Pisciculture has been an important part of the economy in many regions Brazil, and tambaqui (Colossoma macropomum) stands out as one country’s most commercialized native freshwater fish species. Loss genetic variability can affect characteristics such reproduction growth rates, well disease resistance is great concern this field. Molecular markers mitochondrial DNA genes have increasingly used to understand species economic importance. This study aimed characterize populations reared two...
During a survey Myxozoa, four specimens of the sheepshead (18 ± 1.5 cm and 59 2.5 g) (Archosargus probatocephalus) were collected in Ipioquinha river (Maceió/AL). Transmission electron microscopy observations revealed erythrocyte agglutinations gill capillaries located near spherical cysts containing myxospores genus Henneguya. This hemagglutination partially or totally obstructed capillaries. Erythrocytes occurred close adherence to each other, with closed intercellular space. A few lysed...
O objetivo foi avaliar o crescimento, efeito fisiológico e viabilidade econômica de alevinos tilápia do Nilo (Oreochromis niloticus) alimentados com níveis resíduo maracujá (RM). Foram utilizados 100 (1,61 ± 0,01g), masculinizados, distribuídos em 20 aquários (120L) ligados num sistema recirculação água biofiltro por 60 dias.
