Abstract:
The research was conducted from Agustus - September 2020 at the Aquaculture Environmental Quality Laboratory, Faculty of Fisheries and Marine, Universitas Riau. This study aims to determine the effect of feeding made from fish offal on the growth of catfish and the abundance of zooplankton. The method used was a completely randomized design experiment with one factor, five treatments, and three replications. The treatment used P0 = without giving fish offal pellets, P1 =25% of fish offal pellets, P2 = 50% of fish offal pellets, P3 = 75% of fish offal pellets, and P4 = 100% of fish offal pellets. Parameters observed were zooplankton abundance, diversity index, dominance index, specific growth rate, survival, and water quality. The results of the provision of fish offal pellets affected the abundance of zooplankton. The best treatment in this study was the P2 (50% fish offal pellets) with the results of zooplankton abundance of 6686 ind/L, a specific growth rate of 2.80%, a feed conversion ratio of 1.25, and survival rate of 83.33%. Water quality parameters during the research were classified as good, and the temperature was 28-29 0C, pH 6.7-7.0, DO 6.7-7.2 mg/L, and NH3 0.0022- 0.0045 mg/L.

Abstract:
uvenile of Clarias gariepinus (average initial weight 32.89g±0.36) were stocked at a density of 56/m2 in concrete tank and fed diets containing varying levels of poultry offal meal as partial total replacement for fish meal. The poultry offal meal was included at 0%, 10%, 20% and 40% levels of inclusion representing, 0%, 25%, 50%, 75% and 100% replacement of fish meal in the diet of the fish. Results showed that fish fed 20% level of inclusion of poultry offal meal (50%) (replacement of fish meal) had the highest average final weight/fish (104.85g) and a significantly (P<0.05) better feed conversion efficiency (0.53) than the other diets. However, fish on diet containing 40% level of inclusion of poultry offal meal (100% replacement of fish meal) had equal feed conversion efficiency (0.49) as the control and the least cost of feed per unit gain in body weight (₦0.15/g). Feed intake and live weight gain were not significantly (P>0.05) different among all dietary treatments. It is therefore established from this study that poultry offal meal; can completely replace fishmeal in the diet of Clarias gariepinus. The best overall performance was obtained at 50% replacement of fish meal with poultry offal meal.

Abstract:
One of the major problems faced by aquaculture industry today is the high cost of fish feed and this contributes more than 50% of the total cost of production in intensification culture systems. An approach to reduce feed cost is by the substitution of fish meal with alternative cheaper protein sources like fish offal among others. Therefore,&nbsp;this experiment was carried out toevaluate the growth performance and survival of&nbsp;<em>C. gariepinus</em>&nbsp;juveniles fed with diets containing various percentages of fish offal to determine the optimum level of fish offal inclusion in diets of&nbsp;<em>Clarias</em>&nbsp;<em>gariepinus.</em>&nbsp;Five diets of T1(0%), T2(20%), T3(40%), T4(80%) and T5(100%) levels of fish offal&rsquo;s substitutions were formulated to contain 40% crude protein and similar energy levels. &nbsp;The total of 150 juvenile fish was randomly distributed into three replicates of five experimental groups in a (45 x 35 x 28cm<sup>3</sup>) plastic rectangular container. Each replicate consist of 10 fish with a mean weight of 25g. At the end of the experiment, result showed that mean&nbsp;weight gain (MWG), survival rate (SR), protein intake (PI), protein efficiency ratio (PER), feed conversion ratio (FCR), specific growth rate (SGR) and relative growth rate&nbsp;of T0&nbsp;were observed to be statistically p&lt;0.05&nbsp; similar with T1 and T2.&nbsp;The study showed that diets with inclusion rate of 20% and 40% fish offal gave similar result as that fed&nbsp;with control diet. Therefore, fish offal with inclusion rate of 20% and 40%&nbsp;could be fed to&nbsp;<em>C. gariapinus</em>&nbsp;catfish without any negative effects on the growth and survival.

Abstract:
Fish offal and other high protein substrates are generally not suitable for anaerobic digestion because of the high levels of ammonia produced as a result of their biodegradation. In order to efficiently use these types of substrates to produce methane, co-digestion is used to balance the amounts of carbon and nitrogen in the feedstock. In this experiment an optimization procedure for maximizing the methane potential of fish offal, using river tamarind as the co-substrates was developed. Our experimental design tested the effects of substrate to substrate mixtures, as well as overall substrate to inoculum combinations, on the methane potentials. This was performed using batch style biochemical methane potential assays, which employed a methodology developed in our laboratory. The optimum of the 25 combinations tested was 50% fish offal to 50% river tamarind at a substrate to inoculum ratio of 0.03, with a specific methane yield of 144 ± 6 NmL/gFM (330 ± 14 NmL/goDM). This gave much improvement when compared with the fish offal alone, which reached 63 ± 4 NmL/gFM (317 ± 20 NmL/goDM) at maximum. These results indicate that with the correct mixture, rivertamarind is a suitable co-substrate for anaerobic co-digestion of fish offal.

Abstract:
Grouper is one of the demersal fish groups that are abundant in Indonesian marine waters. In addition, the high market demand for this fish has also increased its main production technique as an export product. One example of a product from this fish is fish fillet which still leaves waste. Offal is an example of a by-product of grouper which is underutilized so that it is of low value in the market and as a resource. The high protein content of fish offal can be used as a raw material in the manufacture of protein hydrolysates which of course require the role of proteolytic enzymes. Bromelain enzyme which is a proteolytic enzyme that is protease. This study aims to determine the effect of the bromelain enzyme concentration obtained from pineapple crude extract on the quality of the protein hydrolyzate of grouper offal. The experimental design used in this study was a Factorial complete randomized design with different enzyme concentrations (4, 6, 8, 10). and 12%) and the difference in water bath time (4, 6, 8, and 10 hours). The results showed the bromelain enzyme concentration had a very significant effect on the yield and degree of hydrolysis of snapper offal, and observations of the proximate results showed the potential utilization of hydrolyzed protein of fish offal as a food source.

Abstract:
Abstract Silkworm (Tubifex tubifex) is one of the natural food that is often used in fish farming. Determining the success of silkworm cultivation is strongly influenced by the culture media, which is generally rice mud. Rice field mud is a living medium for silk worms in nature, but the low nutrient content requires the addition of silage of fish offal and fermentation of tofu dregs. This study used a maintenance medium dose of 100% rice field mud (control), 75% fish offal silage + 25% tofu dregs fermentation (P1), 50% fish offal silage + 50% tofu dregs fermentation (P2), and 25% of tofu silage. fish + 75% tofu dregs fermentation (P3). The main parameters in this study were the growth of biomass and population of silkworms during 21 days of rearing. While the supporting parameters of this research are water quality parameters which include temperature, pH, and DO. Analysis of the data in this study using Analysis of Variance (ANOVA) 1 factors. The results of the calculation of optimal biomass and population were obtained in 25% silage of fish offal + 75% fermented tofu dregs with an absolute biomass value of 18.6 grams and an absolute population value of 8,698 individuals.

Abstract:
The extraction of nitrogenous compounds from cod (Cadus morhua) offal by enzymic hydrolysis with papain, the membrane separation of the peptides in the soluble fraction and their freeze and membrane concentration were investigated with the aim of obtaining a high yield of functional products. The following aspects were covered: kinetics of the hydrolysis and of the enzyme inactivation, separation of insoluble solids and yield of nitrogen under different operating conditions (water to fish offal ratio, temperature and particle size of the raw material). Three of the processing options -the hydrolyses, without and with added water, and the water extraction of the minced fish offal followed by hydrolysis of the residue- gave nitrogen yields of 51%, 62% and 69% of the total nitrogen in the fish offal, and required water: fish offal ratios of 0,1 and 1.86 respectively. The peptides in the hydrolysate supernatants were not amenable to membrane separation but those in the water extract supernatant could be split by pH precipitation and ultrafiltration. Eight functional properties of the potential products were evaluated. The hydrolysate supernatants lacked most of them except for high solubility but their low ash content and the particular molecular weight distribution of their peptides may be useful in special feeding diets. The pH precipitate and the concentrate from the ultrafiltration of the supernatant from the pH precipitation exhibited all the functional properties tested to some extent. The precipitate exhibited low solubility and high buffering capacity, high viscosity and good foaming properties. The concentrate had good solubility, gel strength and emulsifying properties.

Abstract:
Multispectral Imaging is an increasingly applied technique for the estimation of several quality parameters across the food chain. The microbiological quality and safety as well as the detection of food fraud are among the most significant aspects in food quality and safety assessment. MSI analysis was performed using a VideometerLab instrument (Videometer A/S, Videometer, Herlev, Denmark), while more than 9000 food samples were examined in total, for the assessment of microbiological quality and the detection of food fraud. For estimating microbial populations, total aerobic counts (TAC) were determined. Several regression and classification algorithms were employed, including partial least squares regression (PLS-R), support vector machines (SVM), partial least squares discriminant analysis (PLS-DA), tree-based algorithms etc. The slope of the regression line, root mean squared error (RMSE), coefficient of determination (R-squared) and accuracy score were used as metrics for the evaluation of models’ performance. In adulteration case, the prediction of different levels of pork in chicken meat and vice versa yielded high accuracy scores i.e., over 90% , while, using the SVM algorithm, the presence of bovine offal in beef was successfully detected. Additionally, Random Forest algorithm was efficient (accuracy&gt;93% ) in discriminating seabass and seabream fish fillets. Concerning microbiological quality, as indicated by the performance indices, the developed models exhibited satisfactory performance in predicting microbial load in different foods (RMSE&lt;1.00, R-squared&gt;0.80). Indicatively, MSI spectral data combined with PLS-R could satisfactorily predict TAC and Pseudomonas spp. counts on the surface of chicken fillets regardless of storage temperature and batch variation based on the performance metrics (R-squared: 0.89, RMSE: 0.88) while, this algorithm presented also satisfactory performance in estimation microbial populations in brown edible seaweed (R-squared: 0.80, RMSE: 0.90). However, in this case, selecting the appropriate analytical approaches and machine learning algorithms is still challenging.
