“…Lower growth performance was observed in Diet I (Pellet feed-control) when compared to other experimental diets. Similar results were observed in the larval rearing of koi carp C. carpio (Sarower-E-Mahfuj et al, 2012). The most striking disadvantages of the pellet feed are due to its size and sinking ability.…”

This investigation aimed to analyze the effects of different diets and determine the optimal feed on the growth performance of guppy Poecilia reticulata (Peters, 1859). In the present study, juvenile guppies were procured from commercial fish breeders, Kolathur, Chennai, and fed with four experimental diets, namely Diet I (Control-Pellet feed), Diet II (Formulated feed), Diet III (Dry Tubifex), and Diet IV (Live feed Brachionus plicatilis) to examine the effects on growth and survival rates. In the experiment, 12 glass circular tanks with a volume of 10 L were used, and ten juveniles having an average body length and weight of 0.8 cm and 0.01 g were randomly introduced into each aquarium (80 cm×30 cm×35 cm) in triplicates. During the experimental study, the fish were fed two times a day ad libitum for 90 days. The various growth parameters and proximate composition of the diets were calculated by following standard methods. The findings showed significant differences (p<0.05) in the fish's various growth parameters fed with different diets. The fish fed with Diet IV 52% crude protein performed better than those provided with lower levels. The increase in growth parameters could be attributed to increased levels of dietary crude protein. However, the diet does not have any significant impact on fish survival rates. Thus, it is concluded that the Live Feed B. plicatilis with 52% crude protein is suitable for theoptimum growth of Poecilia reticulata under the current experimental set-up and recommended for feeding juvenile guppies.

“…CR values lower than 10 −6 show that the exposure of metals is negligible. In contrast, values above 10 −4 indicate that the CR exposure is severe [ 31 , 71 , 72 , 73 ]. In our analysis, the CR values of cultured and wild Barramundi fish showed no carcinogenic risk as all the values were below 10 −6 .…”

Globally, both natural water bodies and aquaculture systems are being severely contaminated by heavy metals due to rising anthropogenic activities. Fish living in aquatic environments can easily accumulate metals in their bodies, which can then be transferred to consumers and put them at risk. In this study, metal concentrations (Pb, Cd, Cr, As, Mn, Cu, Zn) in different organs (gill, liver, and muscle) of farmed and wild Barramundi (Lates calcarifer) fish from the northern Bay of Bengal were evaluated to quantify and compare contamination levels and related human health risk. Heavy metal concentrations were higher in liver tissues of farmed Barramundi than in wild Barramundi, with the following relative mean values in the liver, gills, and muscle: Zn > Cu > Pb > Mn > Cd > Cr > As; Zn > Cr > Cu > Pb > Mn > Cd > As; Zn > Pb > Cu > Cr > Mn > Cd > As; Zn > Pb > Cu > Cr > Mn > Cd > As; and Zn > Pb > Cu > Cr > Mn > Cd > As, respectively. The differences in heavy metal accumulation observed between farmed and wild fish were probably related to the differences in their environmental conditions and dietary element concentrations. However, ANOVA indicated that the variation of metals in wild and Barramundi was not statically significant. Pb concentrations in the liver tissue of farmed Barramundi exceeded the national and international threshold limits, whereas concentrations of other metals were within the limit. Among the examined organs in both fish species (wild and farmed), muscle had the lowest concentration compared to others, and liver was the target organ for Pb, Cu, and Cd accumulations. Metals such as Zn and Mn exhibited higher concentration in the gills. However, all the studied heavy metals were below the maximum permissible limits of national and international standards, but the mean concentrations of Pb and Cd values in the liver of farmed Barramundi exceeded all international and national guidelines. Based on the contamination factors (CF) and pollution indices (PLI and MPI), the degree of contamination in the fish organs was as follows: gills > liver > muscle. The major accumulation tissues for both farmed and wild fish were found to be the gills (MPI = 0.970) and the liver (MPI = 0.692). Based on the estimated daily intake (EDI), the fish samples examined in this study are safe for human consumption as within the recommended daily allowance (RDA) range established by various authorities. According to the Target Hazard Quotient (THQ) and Carcinogenic Risk (CR) calculations, though the Barramundi fishes depicted no potential hazard to humans, farmed fish posed a higher health risk than wild fish.

“…So it is essential to know the proximate composition of the fish to report their nutrient composition from the public health point of view. There are some information on the biochemical and nutritional studies of some freshwater fish species (Sarower-E-Mahfuj et al, 2012). Rubbi et al (1987) mentioned proximate…”

The proximate biochemical contents of some fish species i. e. Thunnus alalunga, Evynnis japonica, Caulerpa lentillifera, Orcynopsis unicolor and Euthynnus affinis were analyzed. Protein contents was determined in T. alalunga (22 %), E. japonica (13.02%), C.lentillifera (26.9%), O. unicolor (22%) and in E. affinis (24%) respectively. Fat content was recorded as 23.3%, 0.24%, 15%, 16% and 14% respectively in the five species of fish. The ash content was highest in C. lentillifera (8.8%). The present findings revealed that the highest protein content was recorded as in C.lentillifera (26.9%), but the fat was highest in T. alalunga (23.3%). The overall nutrient contents of studied medium indigenous fishes were observed as higher or equal to those of larger fish species.
