“…In Pakistan, FCR is observed within the range of 4–8 in traditional earthen ponds ( Janjua, 2015 ) which shows that FCR in tilapia improves with increase in stocking density if pond and feed management are excellent as observed in present study. Previous studies reported the negative impact of high stocking density on growth rate and production of Tilapia in traditional, cage culture and biofloc system ( Abou et al, 2007 , Gibtan et al, 2008 , Chattopadhyay et al, 2013 , Garcia et al, 2013 , Telli et al, 2014 , Moniruzzaman et al, 2015 ; Manduca et al, 2020 ). It shows the possible advantage of IPRS technology over other culture methods for tilapia production.…”

“…Aquaculture products should meet the requirements of food regulations, commercial specifications and standards of World Health Organization (WHO) for human nutrition. High stocking density also reduces flesh quality ( Refaey et al, 2018 ) other than growth, immune response and disease resistance in Tilapia ( Telli et al, 2014 , Manduca et al, 2020 ). However, in present study, careful assessment of protein and lipids quality was performed.…”

In-pond raceway system technology (IPRS) was introduced in Pakistan in 2019 as solution for sustainable aquaculture approach by effectively increasing production, reducing pollution and facilitating feed and pond management. Fingerlings of GIFT Tilapia ( Oreochromis niloticus ) (n = 16,500 in each raceway, initial weight = 32.00 ± 1.26 g) were stocked in June 2019 in two IPRS raceways (area of each raceway = 220 m 3 ) for 171 days until harvested on November 30, 2019. Fingerlings stocked in traditional earthen ponds (area of each pond = 6167 m 3 ) were studied as control (n = 3000 in each pond, initial weight = 32.00 ± 1.26 g). Average harvested biomass from raceways was 57.33 kg/m 3 with an average daily weight gain per fish of 4.47 g per day. On the other hand, average harvested biomass from control ponds was 0.38 kg/m 3 with an average daily weight gain per fish of 4.60 g per day. Average feed conversion ratio (FCR) in both raceways and control ponds was recorded as 1.25 and 1.24, respectively. Overall survival rate in both raceways and control ponds was above 99%. No sign of any disease was noted at any stage in both study groups. Crude protein and fats contents did not reduce in any raceway despite of high stocking density and sharp seasonal changes. Profile of essential and non-essential amino acids were found to be upto nutritional requirements of adult human. High levels of n-3 and n-6 fatty acids in fish collected from raceways as compared to those in traditional earthen pond show that muscle quality was not compromised due to high stocking density in small area. Return on investment excluding capital cost was 47.05 which implies that IPRS technology can be economically feasible with further modifications.

“…The Nile Tilapia was the focal species in all studies listed here. Manduca et al 2020Manduca et al , 2021 health attention. Florfenicol is reported as the antibiotic most commonly used against streptococcosis in tilapia culture (Oliveira et al 2018), whereas oxytetracycline is among the most widely used drugs for treating fish in some countries, especially against S. iniae (Darwish and Griffin 2002).…”

Tilapia culture is a very promising industry within the aquaculture sector. However, disease outbreaks have continued to threaten the industry, causing serious economic losses among the producers. Streptococcosis has become the major bacterial disease affecting tilapia production in most regions of the world. To combat the disease and minimize its economic impact on fish producers, numerous preventive and control measures have been developed and reported over the years. This paper aims to systematically review the measures that could be used to manage the disease outbreaks and maintain fish health based on previously published scientific studies. Although numerous measures currently available have been highlighted, it is far better for the producers to maximize the preventive measures for management to be economically feasible. Among the currently available preventive measures, the use of vaccines has been shown to have the most promise, while the use of herbs has been demonstrated to be a more sustainable and economically affordable control measure. However, there are still a number of important gaps in existing literature that require further investigation. Overall, significant progress has been made in preventing and controlling streptococcosis in tilapia although, no single effective measure has been identified. Therefore, a combination of these measures may provide a more effective result.

“…Neste estudo, os autores indicaram até 10% de nível de inclusão de farinha de T. molitor em dietas para juvenis de tilápia, proporcionando um ótimo desempenho zootécnico dos peixes e a diversificação de microrganismos no sistema BFT. Manduca et al (2020) verificaram os efeitos de diferentes densidades de estocagem entre 20, 40, 60 e 80 peixes.m -3 de juvenis de tilápia do Nilo sobre qualidade da água, desempenho de crescimento, composição corporal, morfometria branquial e bioquímica sanguínea dos peixes criados em sistema BFT de troca zero de água. O estudo demonstrou que o desempenho zootécnico dos peixes em densidades de estocagem de 20 e 40 indivíduos.m -3 foi superior aos demais, especialmente para ganho de peso diário e taxa de sobrevivência.…”

O objetivo deste estudo de revisão foi avaliar a sustentabilidade econômica, social e ambiental da biotecnologia bioflocos no cultivo de tilápia do Nilo Oreochromis niloticus. Com uma revisão sistemática, utilizou-se como metodologia os detalhamentos dos critérios de exclusão e inclusão adotados para a seleção da amostra e análise dos conteúdos das publicações. Os artigos utilizados neste estudo foram pesquisados nas bases Scopus e Web of Science. Foi utilizada a metanálise, optando-se pela natureza mista, ou seja, qualitativa e quantitativa de artigos publicados nas revistas científicas no período de 2008 a 2021. Constatou-se que a avaliação econômica, social e ambiental que contempla o desenvolvimento sustentável encontra-se em fase inicial de abordagem, face ao número de artigos que contemplam o assunto no período analisado. Os estudos envolvendo a biotecnologia de bioflocos contemplados nessa metanálise pertencem especialmente a ordem técnica, seguida da sustentabilidade da tecnologia empregada e aspectos positivos com relação ao âmbito econômico. Não obstante, há um déficit na abordagem dos aspectos sociais envolvidos com a aplicação desta biotecnologia.
