“…As a result, the concentration of liquid smoke and immersion duration did not affect the fat content of sausages because the liquid smoke compounds could not dissolve non-polar fat. The fat content of smoked sausages was not highly different [25], which found that the fat content of African catfish sausages was in the range of 12.08 -15.94% dw.…”

Product diversification is needed to increase selling and marketing prices. One of them is the African catfish sausage product. Liquid smoke has been used commercially by the food industry. This study aimed to determine the physical and chemical properties of smoked African catfish after adding different concentrations of liquid smoke and immersion duration. The chemical analysis measured the levels of protein, fat, and phenol. The results showed that sausage with a concentration of 20% liquid and soaking for 30 minutes was the best treatment with a protein content of 43.8 ± 0.34%, a fat of 12.33 ± 0.61%, and phenol 292.74 ppm. Determination of the compound using GC-MS found that the most dominant compound in the smokeless sausage was 2-hexanone, 3,3 dimethyl with a relative concentration of 32.42%. The dominant compound in the besttreated sausage was Furan, tetrahydro-2,2-dimethyl- with a relative concentration of 19%. Liquid smoke penetration is clearly visible in the microstructure of smoked sausages, both in the best-treated smoked sausages and commercial sausages. Scanning Electron Microscope (SEM) magnification of 2.500x shows that the best emulsified smoked sausages have a flatter structure, smaller droplets, and are more refined than smokeless sausages or commercial smoked sausages.

“…Lipid deposits were observed in Clarias gariepinus after the addition of palm oil in the diet [14]. Other studies have shown that diets containing large amounts of fat lead to changes in body composition characterized by an increase in body fat accompanied by a decrease in the water content [34,35]. This could explain the observed decrease in the function of increasing the fat content of food distributed moisture content.…”

This study showed clearly the effect of adding palm oil to the diet of farmed fish to replace marine animal oils. For this purpose, four foods based on maggot flour at 35% protein with the incorporation of palm oil, at different levels at 0, 2, 5 and 10% were tested in the to assess their impact on the improved growth performance, food utilization, survival rate and biochemical composition of Heterobranchus longifilis larvae Four experimental diets were formulated based on the maggot meal as the main protein source. These diets were formulated at 35 % protein levels with maggot meal and maize flour as the major ingredients containing different concentrations of palm oil levels at 0, 2, 5, and 10 %. This study was carried out in the reproduction laboratory, at Oceanological Research Center, Abidjan, Côte d’Ivoire, between the periods of September to November 2022. The diets were offered to the larvae (average initial weight 0.004 ± 0.001 g) three times a day ad libitum for 49 days. At the end of rearing, the results showed that the different experimental foods distributed did not influence the quality of the rearing environment. The best growth was obtained with the larvae subjected to diet containing 2% palm oil with a final average weight of 3.21 g and a conversion index of 1.63. Beyond this rate, larval growth decreases. Survival rates vary from 70 to 73 %. The conversion ratios are not significantly different and ranged between 1.63 and 2.3. On the biochemical larvae submitted to diet containing 10 % of palm oil had body lipid content (2 %) and high ash rich. As against a gain of protein is observed with larvae submitted to diets containing 2 % palm oil reflects an effect of protein. From the present results, diet containing 2 % crude palm oil is considered optimal for Heterobranchus longifilis larvae.

“…Sapu-sapu fish contains 16.85±4.35% crude fat, higher than the fish meal of 10% (Applegate and Angel 2014), catfish 2.1-3.8% (Gökoğlu and Yerlikaya 2015), catfish Africa (Clarias gariepinus Burchell, 1822) of 9.3±0.3% (Effiong and Yaro 2019). The amount of variation in the nutritional content of these fish is influenced by species, individual, age, sex, environment, and season (Gökoğlu and Yerlikaya 2015;Merdzhanova et al 2021;Koca et al 2023).…”

Abstract. Asnawi. 2023. Heavy metal content in duck eggs and meat that consumes feed containing Sapu-sapu fish (Hypostomus plecostomus). Biodiversitas 24: 3201-3206. This study aimed to evaluate heavy metals in the eggs and meat of ducks feeding on the Sapu-sapu fish (Hypostomus plecostomus Linnaeus, 1758) on Lombok Island, West Nusa Tenggara, Indonesia. The observation of collected Sapu-sapu fish samples from three major Mataram rivers. Duck eggs and meat were collected from a livestock group that fed Sapu-sapu fish. The observed variables include; macronutrients (moisture content, crude protein, crude fat, crude fiber, and ash) and heavy metal content (Cu and Pb) in the Sapu-sapu fish, duck meat and eggs fed by Sapu-sapu fish. The study found that the Sapu-sapu fish possesses complete macronutrients, making it a possible duck feed. The heavy metal content of copper (Cu) in the Sapu-sapu fish ranges from 189.314±0.0238 ppm, while the lead (Pb) content ranges from 4.25±0.18 ppm. The average heavy metal content of Cu in the eggs and meat of ducks consuming Sapu-sapu fish was 7.692±2.158 ppm and 14.523±6.481 ppm, while the levels of lead in eggs and meat of cesarean fish were 0.936±1.557 ppm 0.373±0.211 ppm. The study concluded that the Sapu-sapu fish in the Mataram city stream has a complete nutritional content (protein, fat, amino acids, minerals) but contains high heavy metals. Therefore, if consumed, ducks dispose of it into the eggs and duck meat. As a result, the eggs and meat of ducks that consume sapu-sapu fish contain heavy metals Cu and Pb that exceed the threshold, so they are unsafe for human consumption.
