“…Gomez-Marquez [41] observed 1 to 4 year classes of O. niloticus from coastal Mississippi, USA. The growth increments of fishes are a natural process that can be driven by environmental and habitat conditions [4,6,12,44]. Grammer [45] reported slow growth rate of O. niloticus compared to present findings from tropical shallow lakes in Mexico.…”

Oreochromis niloticus species are adapted to their own set of local ecological and climatic conditions from the Paisuni river, India. Consequently, environmental conditions and their connectivity to organisms may play a big role in generating growth outcome of non-native species in natural conditions. Study was undertaken during the period of October 2015 to September 2016 from the Paisuni river, India. Invasive potential of O. niloticus was measured through size composition, age and growth from the Paisuni river. The total length of fishes varied from 96 to 398 mm with 0+ to 6+ age groups. Their size groups and age groups indicated that the O. niloticus are well stable in the Paisuni river. Their stock and density from the Paisuni river are helping to fisher community for their livelihood and malnutrition as well as poor men malnutrition. The maximum growth increment was observed in 1+ age group (145 mm) and minimum in 6+ age groups (14 mm). The growth of fishes very systematically declined after 1+ age group in the Paisuni river. The maximum fishes were exploited in 241 to 270 mm size group with 18.39%. These sizes of fishes are very attract and magnetize to the fishers from the Paisuni river.

For A. nigrofasciata, the maximum age was 3.42 years; for O. niloticus, the maximum age was 13 years; for T. zillii, the maximum age was 7.92 years.…”

Bertalanffy proposed the differential equation m´(t) = p × m (t) a-q × m (t) for the description of the mass growth of animals as a function m(t) of time t. He suggested that the solution using the metabolic scaling exponent a = 2/3 (von Bertalanffy growth function VBGF) would be universal for vertebrates. Several authors questioned universality, as for certain species other models would provide a better fit. This paper reconsiders this question. Using the Akaike information criterion it proposes a testable definition of 'weak universality' for a taxonomic group of species. (It roughly means that a model has an acceptable fit to most data sets of that group.) This definition was applied to 60 data sets from literature (37 about fish and 23 about non-fish species) and for each dataset an optimal metabolic scaling exponent 0 ≤ a opt < 1 was identified, where the model function m(t) achieved the best fit to the data. Although in general this optimal exponent differed widely from a = 2/3 of the VBGF, the VBGF was weakly universal for fish, but not for non-fish. This observation supported the conjecture that the pattern of growth for fish may be distinct. The paper discusses this conjecture.

Bertalanffy proposed the differential equation m´(t) = pm(t) a-qm(t) for the description of the mass growth 10 of animals as a function m(t) of time t.

“…The human activities have powerfully altered size, age, sex ratio, fecundity, feeding nature, exploitation and biodiversity of fishes especially from the freshwater ecosystems over the world [2][3][4][5][6][7][8][9]. In general, Oreochromis niloticus (Nile tilapia) is eminent for their plasticity in survival, feeding nature, fast growth, tolerance, ease of breeding and size-at first maturity that not only compose them the ability to invasion in any fresh water ecosystem and become established in non-native ecosystem or introduced ecosystem (example habitats, environments) but also allow them an excellent aquaculture species (Example due to its ability to tolerate a wide range of environmental conditions and ability to feed at different trophic levels) with other carps [10][11][12][13][14][15][16]. It is naturally distributed in the Nile River as well as most parts of African rivers, reservoirs and lakes while it is exotic fish species for India [17][18][19][20].…”

The natural fishery or wild stock of fishes especially fresh water in India is significantly declining due to manmade stressors. The invasion of fishes and size composition are an essential component of stream, river and other large water bodies ecosystem and represents an evident of structure, function, depth and health of stream/river. During study period 683 specimens of Oreochromis niloticus were collected from February 2019 to January 2020 in Sirsa fish landing centre from the lower stretch of the Tons river at Prayagraj, Uttar Pradesh, India. Size composition of fishes was varied from 82 to 463 mm (total length). The maximum total length of O. niloticus in the catches indicated that its increasing colonisation success in the river Tons. Size composition of fishes was also indicated that the stock of O. niloticus in the Tons river was in healthy condition. The 231-260 mm size group was most dominated (15.67%) compared to 261-290 mm (12.44%) and 291-320 mm (11.71%) in the total exploited stock. The middle size group was maximum exploited with 51.24% from the Tons river at Prayagraj. Higher size group contributed sizeable proportion with 25.04% in the exploited stock. The exploitation pattern was unsystematic in higher size group due to contribution of higher proportion. Current exploitation pattern is unsystematic but O. niloticus is powerfully invaded from the lower stretch of the Tons river at Prayagraj.
