“…Citric acid 3% and phytase 1000FTU/kg was considered best in the present study with positive effect on protein contents of fish. Similar results were obtained by Shah et al (2016) in Labeo rohita. But Nezhad et al (2008) stated that citric acid may not affect the ability of phytase in chicks.…”

Rohu fish is tastiest fish among carps but its production is less than other species due to its slow growth and high mortality due to unavailability of suitable diet especially at juveniles stage. This study focus on the healthy production with low cost by using sunflower meal to some extent replace fish meal. In this 3× 3 factorial and completely randomized design study 324 fish were used. The acidification levels were (0, 1.5 and 3%) whereas the phytase levels were (0, 500 and 1000 FTU). The addition of 3 % citric acid and 1000FTU phytase produced significant interaction effect on calcium and phosphorus digestibility and different body contents of L. rohita. Phytase and citric acid increased the digestibility of calcium and phosphorus with improvement in body dry matter, protein, fat, energy and ash contents of L. rohita. Acidification and phytase supplementation showed significant (P < 0.05) interaction on body composition and mineral utilization in rohu. Citric acid and phytase supplementation improves the diet by increasing the availability of minerals and quality of fish by positively affecting the body composition of fish. 3% citric acid and 1000FTU phytase proves to be interacted positively. Further study is required to find the optimum levels of phytase and citric acid in this regard.

“…Indeed, the length of weaning period can be shortened and the number of successfully weaned fish increased when the O. marmorata juveniles were weaned using the pH 2.5 and pH 3.2 acidified diets, rather than the control diet (pH 6.0) (Lim et al, 2018). It is known that feeding the acidified diets to fish can enhance their growth performance and feed utilization (Lückstädt, 2008;Phromkunthong et al, 2010;Tabrizi et al, 2012;Sherif and Doaa, 2013;Zhu et al, 2014;Shah et al, 2015). However, the growth performance and feed utilization of marble goby offered the acidified diets are still unknown.…”

The present study was aimed at evaluating the growth performance and feed utilization of marble goby (Oxyeleotris marmorata) juveniles fed with the acidified diets (AD). In feeding trial I, five fish meal-based diets were prepared [control (pH 6.0), AD 5.3, 4.3, 3.2 and 2.5]. Each diet was fed to triplicate batches of wild-caught O. marmorata (19 fish/ tank; total length, TL = 4.72Â±0.46 cm) for 8 weeks. The control, AD 5.3, and AD 4.3 treatments were terminated at week 4, due to drastic decline in total feed intake (TFI=0â€“0.05 g) and weight loss (weight gain, WG = -15.3 to -16.9%) in the fish. The AD 3.2 and AD 2.5 treatments were continued until week 8. Fish fed with the AD 3.2 showed significantly higher (P < 0.05) TFI (0.98 g) compared to those fed with the AD 2.5 (0.73 g) at the end of the trial. Feeding trial II was done to assess the long-term effects of AD for another 7 weeks. Thirty fish specimens were randomly selected from each of AD 3.2 and AD 2.5 treatments and stocked individually in 7 L aquaria to eliminate the territorial behaviour that was observed in the first trial. At the end of the experiment, fish fed AD 3.2 attained significantly higher (P < 0.05) WG (34%) than those fed AD 2.5 (13%). However, the growth performance and feed utilization results of the present study were very poor compared to those fed the normal fishmeal-based diet as is evident from synthesis of data from the literature review. Feeding of acidified diets was, therefore, not recommended for an extended period (> 3 weeks). Nevertheless, based on the strong preference of the fish for AD, it is worth trying to develop a weaning protocol using these diets as the starter feed and then slowly replacing them with the normal diet.
