“…In this work, it has been pointed out that at a global level, there is a sustained trend towards an increase in the production of aquatic resources, and that this trend is supported only in aquaculture since fisheries have reached their maximum sustainable level. However, the main problem facing aquaculture is that being an economic activity, profit margins are frequently narrow and sometimes nil 97 . This is possibly due to poor planning, control and monitoring of production and the occurrence of external factors that are difficult to control but are feasible to measure, analyse and learn from them.…”

“…Like protected agriculture, it would be ideal for aquaculture to evolve towards the modernisation of production systems to produce more and in less volume, with fewer risks, with control of variables, such as water temperature, which greatly influences growth and survival of organisms and disease control. However, much of the world's aquaculture is carried out in a rustic way, without control of environmental variables and with little knowledge of production costs 97 …”

The global production of aquatic resources is increasing at the rate of 3.3 million tons per year, main thanks to aquaculture. However, this industry is considered by financial institutions as high risk due to failures caused by epizootics, natural disasters and poor planning and monitoring. Bioeconomic modelling is a progressive branch of social science that seeks to integrate the disciplines of economics and biology to create theories that better explain economic events using a biological basis and vice versa. This should be used in aquaculture to plan, monitor, and determine cost‐effectiveness and risk, to reduce uncertainty and increase profits of ongoing or new projects. A meta‐analysis of the literature on bioeconomic modelling in aquaculture during 26 years (1994─2020) was performed, using four search engines. Sixty‐eight articles were published in 23 journals, on 25 groups of species or species. The most studied were shrimp, tilapia, seabream, salmon and carp. From these, 12 articles dealt with tilapia models that shared similar biological, management and economic sub‐models. In the 26‐year analysis, the global scientific productivity in this field is low (2.6 articles/year) in relation to the growth of world aquaculture. Bioeconomic modelling peaked during the decade from 2004 to 2014 with 5.6 papers/year, but then declined to only 0.83 articles/year from 2015 to 2020. This is possibly due to the low diffusion among producers, planners and financial institutions of the advantages of the models and the difficulty to use them if friendly and readily available software is lacking.

“…Red tilapia ( Oreochromis spp.) is recognized as an important farmed fish species worldwide because it can easily adapt to the environment and has a fast growth rate [ 1 , 2 ]. However, growth retardation at the onset of sexual maturity and overpopulation by excessive or unwanted reproduction are the major concerns for mixed-sex red tilapia production.…”

The aim of the present study was to optimize a masculinization platform for the production of all-male red tilapia fry by oral administration of 30 and 60 ppm of MT and alkyl polyglucoside nanostructured lipid carriers (APG-NLC) loaded with MT, respectively, for 14 and 21 days. The characterization, encapsulation efficiency and release kinetics of MT in lipid-based nanoparticles were assessed in vitro. The results showed that the MT-loaded nanoparticles were spherical, ranging from 80 to 125 nm in size, and had a negative charge with a narrow particle distribution. The APG-NLC loaded with MT provided higher physical stability and encapsulation efficacy than the NLC. The release rate constants of MT from MT-NLC and MT-APG-NLC were higher than those of free MT, which is insoluble in aqueous media. There was no significant difference in survival between the fish administered MT or the those fed orally with MT-APG-NLC fish. According to the logistic regression analysis, the sex reversal efficacy of MT-APG-NLC (30 ppm) and MT (60 ppm), resulted in significantly higher numbers of males after 21 days of treatment compared with the controls. The production cost of MT-APG-NLC (30 ppm) after 21 days of treatment was reduced by 32.9% compared with the conventional MT treatment group (60 ppm). In all the treatments, the length–weight relationship (LWR) showed negatively allomeric growth behavior (b < 3), with a relative condition factor (Kn) of more than 1. Therefore, MT-APG-NLC (30 ppm) would seem to be a promising, cost-effective way to reduce the dose of MT used for the masculinization of farmed red tilapia.
