The use of aquaponic systems has grown in recent years, but few these have integrated the production prawns and short-cycle vegetables. This study evaluated potential for producing microgreens (beet, amaranth, arugula, red cabbage) with Amazon River (Macrobrachium amazonicum) an system. Four seeding densities (5, 10, 15, or 20 seeds/cell) were assessed two treatments: one using prawn wastewater other plain dechlorinated water (control). Water quality, growth performance, microgreen...
Colossoma macropomum is the second largest scaled fish of Amazon. It economically important for commercial fisheries and aquaculture, but few studies have examined diversity genetic structure natural populations this species. The aim study was to investigate levels variability connectivity that exist between three C. from Amazon basin. In total, 247 samples were collected municipalities Tefé, Manaus, Santarém. genotyped using a panel 12 multiplex microsatellite markers. found in these high...
Over the years, aquaponics has become a powerful technological tool that allows sustainable production of food, integrating conventional fish farming with vegetable production. The present study evaluated late seedlings açai Euterpe oleraceae in an aquaponic system tambaqui Colossoma macropomum. A total 36 tambaquis initial average weight and length 1086.75 ± 16.38 g 38.49 0.90 cm were distributed 12 independent units, totaling 3.62 kg m−3. fed three times daily commercial feed at rate 3%....
The objective was to evaluate the hematological and biochemical blood parameters performance of Colossoma macropomum submitted BFT maturation under different feeding regimes. carried out for 60 days (Phase 1). Feeding on six or seven a week rates 4% 6% biomass were tested 2). water quality monitored throughout experimental period. At end Phases 1 2, samples zootechnical evaluated. In Phase 1, total ammonia higher 17th day (1.25 mg TAN L−1) stabilized from 21st onwards. Nitrite reached peak...
The study tested the use of Artemia salina nauplii as first exogenous feeding in larviculture Hypancistrus sp. Moreover, we aimed to assess quantity prey concentrations and stocking density during 30 days feeding. Experiment I: larvae were fed with four initial concentrations, T100: 100, T200: 200, T300: 300 T400: 400 A. nauplii/larvae/day. increased every six adequate larval growth. II: kept at densities, 1, 5, 10 15 larvae/L. In both experiments, consumed success for larvae. Best growth...
The objective of this study was to evaluate menthol and eugenol as anesthetics for early juveniles curimba, Prochilodus lineatus. Juveniles 4.0±0.5 g a total length 8.8±0.1 cm were exposed the (20, 30, 40, 50, 60, 70, 80 mg L−1) 70 up deep anesthesia. anesthetic effects evaluated measuring induction time anesthesia (characterized by loss equilibrium, absence swimming, reduction opercular movements, responses only intense tactile stimuli), recovery time, appetite return, mortality rate after...
The production of high-quality seedlings is important to achieve better productivity in horticulture. Despite being well developed conventional agriculture, there are few studies on aquaponic systems. substrate choice this integrated culture affects plant and economic feasibility. This study verified the effects using Euterpe oleracea residue as a for Coriandrum sativum seedling an system with tambaqui, Colossoma macropomum. Five mixtures offal (0%, 25%, 50%, 75% 100%) coconut fiber,...
Genetic variability is one of the important criteria for species conservation decisions.This study aimed to analyze genetic diversity and population differentiation two natural populations Arapaima gigas, a with long history being commercially exploited.We collected 87 samples A. gigas from Grande Curuai Lake Paru Lake, located in Lower Amazon region Amazônia, Brazil, genotyped these using multiplex panel microsatellite markers.Our results showed that analyzed had high levels variability,...
Anesthetics have been used frequently in aquaculture to minimize stress during handling. However, several factors can affect the efficiency of anesthetics. For example, temperature is one abiotic that control animal metabolism and consequently, effect This study aimed evaluate effectiveness benzocaine as an anesthetic for early juveniles curimba Prochilodus lineatus at different water temperatures. Juveniles (4.7 ± 1.6 g total length 7.4 0.7 cm) were submitted anesthesia concentrations 30,...
O presente estudo foi realizado para determinar a variação nictemeral do ictioplâncton no estuário rio Curuçá, Pará. material de estudo, ovos e larvas peixes, coletado em 24 amostras 3 estações, por uma rede plâncton cônica, com 500 μm abertura malha, arrastos na sub-superficie da coluna d'água, 5 minutos duração.
The present study analyzed the genetic variability and structure of farmed tambaqui in Brazilian state Pará, provided basic information that can be used for development programs monitoring management resources aquaculture operations northern Brazil. A total 216 individuals were sampled from farms Pará. Genotyping was based on a multiplex set 10 tri- tetra-nucleotide microsatellite markers. data to calculate diversity indices, expected observed heterozygosity, number alleles per locus,...
