Effect of dietary supplementation of minerals premix on growth performances and return in red tilapia (Oreochromis nilloticus x Oreochromis mossambicus)

Abstract

Tilapia is a popular fish for consumers and aquaculture in every part of Thailand. This study was conducted to determine the level of mineral supplementation in the diet for the growth of red tilapia fingerlings, which gave the lower fish production cost. The fingerlings with an initial average weight of 3.1 ± 0.48 g and a length of 2.5±0.24 cm were raised in 3 m3 concrete tank with 1.5 m3 of water volume at 20 fish/m2 stocking density. Fish were fed with pellets diet (28 % crude protein), which contained different levels of mineral supplements (0 (control), 20 and 40 g/Kg) in triplicate replications. The experiment was conducted within 80 days. The results showed that fish fed with diet3 had better average daily weight gain (ADG) and food conversion ratio (FCR) than diet2 and diet1 significantly (P<0.05). The ADG and FCR of fish fed with diet3 showed 0.70 ± 0.02, 1.72 ± 0.02 respectively, but there was a non-significant difference in survival rate from all treatments (P>0.05), and the fish production cost of diet 3 is lower than those in diet1 and diet2. Thus, this experiment concluded that minerals supplementation at the level 40 g/kg diet were suitable for tilapia aquaculture.

The influence of napier grass biomass mixed feed on the biorefinery indicator for Nile tilapia production

“…Several studies often use growth test results to determine the composition of a carcass [ 5 , 6 , 10 ]. A low-protein diet can reduce the production of meat, but it also makes the meat fattier and more saturated.…”

“…The high price of aquafeed due to many types of feedstuff, especially fish meal, is expensive and continually rising [ 5 ]. In addition, the current outbreak of Covid-19 (Coronavirus Disease-2019) and the war also affected the high prices of feedstuff and aquafeed.…”

Enhancing enzyme digestibility of red tilapia (Oreochromis niloticus and O. mossambicus) and improving water quality in fish farming using Napier grass silage

“…Intensive fish farming involves cultivating fish at high stocking densities leading to improved fish feeding efficiency through enhanced utilization of essential digestive enzymes, such as protease, lipase and amylase (Thongprajukaew et al, 2017). For example, tilapia have various digestive enzymes in their stomach and intestines (Hangsapreurke et al, 2020;Is-haak et al, 2020). Pepsin and other enzymes are most active in highly acidic environments (Moyle and Cech, 2000).…”

Impact of water temperature on the shipping of berried female broodstock (Macrobrachium rosenbergii): A study on survival, egg retention, hatching duration, and hatching success rate

“…While Asia remains the epicenter of this crustacean's success, its allure has also begun to enchant Caribbean waters. The aquaculture sector in Thailand has long relied on the economic (Hangsapreurke et al, 2020;Tongmee et al, 2020) and ecological contributions of the M. rosenbergii, a species integral to both food security and commercial enterprise.…”
