Proposal of Ecotechnologies for Tilapia (Oreochromis niloticus) Production in Mexico: Economic, Environmental, and Social Implications
نویسندگان
چکیده
Conventional aquaculture (ACUA-C) in Mexico is an activity that maintains annual growth rate of 6%. Tilapia (Oreochromis niloticus) the predominant country with 4623 farms, most which operate semi-intensive (SIS) and extensive (ES) production systems, discharging untreated wastewater negatively impacts environment. To address this problem, new ecotechnologies such as biofloc (BFT), recirculation systems for (RAS), constructed wetlands (CWs) water treatment, aquaponics (AS) have emerged to mitigate environmental wastewater. The objective work evaluate feasibility tilapia farming BFT, RAS, CW, AS through economic financial analysis, considering their social implications a Mexican farm located state Veracruz. Open interviews, direct observation, diagnosis system was carried out between 15 May 2019 February 2020 order calculate, design, theoretically four ecotechnological alternatives (TBF, AS). Economic (13), (10), (5) variables were applied, making use same facilities. results reveal implemented SIS are economically viable environmentally acceptable, especially management, addition being socially feasible. It concluded BFT offers alternative producer by having lower additional cost improve problems, despite possible complexity operation energy requirements manage treatment. technological transition recommended solve problem sustainable management.

Tol2-mediated transgenesis in tilapia (Oreochromis niloticus).
The Nile tilapia (Oreochromis niloticus) is an important species in aquaculture and an excellent model system for laboratory studies. Functional genetic analysis using this species has been difficult because existing methods for producing transgenics are inefficient. Here we show that the Tol2 transposon system can be used to create transgenic tilapia with high efficiency. We constructed a line...
متن کاملProduction of genetically male tilapia through interspecific hybridization between Oreochromis niloticus and O. aureus
This study was conducted to produce a high percentage of genetically male tilapia through interspecific hybridization between Nile tilapia, Oreochromis niloticus and Blue tilapia, O. aureus and evaluate sex ratio, productive performance and heterosis of the progeny produced. The results revealed that sex ratios of the progenies of (♀ O. aureus x ♂ O. niloticus) and (♀ O. niloticus x ♂ O. aureus...

متن کاملProximate composition of selected potential feedstuffs for Nile tilapia (Oreochromis niloticus Linnaeus) production in Kenya
Nutrition is vital in fish farming because feed costs represent 40–50 % of the total variable production costs (SHANG, 1992; CRAIG and HELFRICH, 2002). For several decades, fishmeal has been used as the main source of protein in fish feeds (TACON and JACKSON, 1985; TACON, 1993; EL-SAIDY and GABER, 2004; ALCESTE and JORY, 2000). However, the periodically occurring low availability, competition a...
متن کاملStrategies for Nile Tilapia (oreochromis Niloticus) Pond Culture
Different strategies for Nile tilapia (Oreochromis niloticus) culture in ponds with a series of progressive inputs were compared. The sequential experimental stages to increase fish production through intensification were: 1) triple superphosphate (TSP) only; 2) chicken manure only; 3) chicken manure supplemented with urea or urea and TSP; 4) urea and TSP; 5) continually supplemental feeding; 6...
