There is unavoidable need for fish smoking as a preservative technique to reduce rampant post harvest losses in the tropical Africa. However the imperative of healthier and quality smoked products through improved processing method were however investigated. Organoleptic and chemical assessment of African catfish collected from a reputable fish farm in Ogbomoso, Oyo state Nigeria was carried out. Eviscerated and non-eviserated fish samples were smoked using four different smoke sources: Gmelina (Gmnelina arborea), Parkia (Parkia biglobosa), Neem (Azadirachita indica) and charcoal. Overall acceptability was based on 5-point Hedonic scale (excellent (5) - poor (1). Chemical test was on Polycyclic Aromatic Hydrocarbon contents (benzo(a)pyrene, Fluoranthene, Napthalene, Acenapthalene, Chrysene and Benzo(ghi) perylene). Data were subjected to one way Analysis of Variance (ANOVA) using general linear mode (GLM) of Factorial Experimental Design and means were separated by Duncan’s multiple range tests (P<0.05). Non- eviscerated smoked African catfish samples had lower scores for colour than eviscerated smoked samples for energy sources used. Eviscerated samples had mean scores of 4.64, 3.91, 3.36 and 2.82 for charcoal, Gmelina, Neem and Parkia smoked samples respectively, much better than scores of 4.36, 2.46, 2.36 and 2.27 obtained for non-eviscerated samples. Total concentrations of polycyclic aromatic hydrocarbons (PAH) were highest in samples produced using Gmelina as smoke source and Neem for eviscerated (15.25 µg/kg) and non-eviscerated (29.43 µg/kg) samples respectively. Evisceration of fish prior to smoking enhances its sensory characteristics however; concentrations of PAHs for both eviscerated and non-eviscerated fish samples were within the recommended international standard limit.

Japanese threadfin bream (Nemipterus japonicus) is a demersal fish that plays a very important role in maintaining ecosystem stability related to webs and food chains. This fish often becomes prey for predatory fish. In efforts to reveal the relationship between predators and prey in food webs and food chains, there is still limited information due to the difficulty of identifying digested food. In connection with this, this study aims to identify the morphology shape index value otolith of Japanese threadfin bream. Sampling was carried out at the Labuang Maros Fish Landing Site with 150 samples and morphometric data were collected from 150 pairs of otoliths in April and May 2023. The calculation of the shape index uses six descriptors, which include form factor (FF), roundness (RO), circularity or compactness (C), rectangularity (Rt), ellipticity (E), and aspect ratio (AR). The results showed that there was no significant difference in the otolith morphometry of the right and left otoliths (P>0.05). Based on the shape index value obtained, it explains that the morphometric shape of the otolith of Japanese threadfin bream tends to be oval, elongated, and has an irregular surface.

Aims: The aim was to contribute to the improvement of Clarias jaensis productivity through the evaluation of the effect of the substitution level of soybean meal by Chromolaena odorata leaves powder on the survival rate and growth characteristics of Clarias jaensis juveniles. Place and Duration of the Study: From April to June 2019 at TAWON (LN: 5°10' - 5°20' and LE: 10°20' - 10°21'). Sudano-Guinean altitude zone of West Cameroon. Study Design: Two hundred and twenty-five Clarias jaensis juveniles (12.44 ± 0.15g) were divided into five treatments corresponding to 0; 10; 15; 20 and 25% of substitution level of soybean meal by Chromolaena odorata leaves powder. Methodology: They were fed twice a day (8:00 A.M. and 6:00 P.M.) at 5% of ichthyobiomass, total length, live body weight and physicochemical parameters were measured every tree week for 84 days. Results: At the 15% substitution level of soybean meal, the survival rate was the highest (100%). Mean Final Weight and Mean Daily Weight Gain were significantly (P≤0.05) higher at 15% (45.73 ± 7.45g and 0.56 ± 0.31g/d). Specific Growth Rate and Condition factor K were higher at 25% (1.41 ± 0.68%/d and 1.08 ± 0.22%g/cm3), however, no significant differences were recorded. The cost of feed to produce one kg of C. jaensis was lower at 15% (609.61 Fcfa). Conclusion: Soybean meal can be substituted by C. odorata leaves powder at 15% in feed for C. jaensis juveniles.

The aim of this research is to evaluate growth parameters in post larvae catfish in relation to feed types. This study will analyze the trend for length of Claria gariepinus fed on commercial feed, maggot and zooplankton; analyze the trend of weight of Claria gariepinus fed on commercial feed, maggot and zooplankton; analyze the relationship between length and weight and; make forecasts for the length and weight of the fish fed on the specified feed types. Artificial reproduction of African Catfish (C geriepinus) was carried out using the hypophysation technique. Brood stocks were selected from centrally located parent stock holding ponds. Males and females were conditioned in separate ponds. The brood stocks were fed with 20% crude protein formulated feed, acclimatized for three weeks, then transferred into the hatchery holding tanks between 240 Celsius and 270 Celsius to stimulate ovulation after injecting the females with 0.5ml of ovalin. Fertilized eggs were incubated in continuous flow of water until hatching was completed. A commercial starter feed consisting of 8% ash, 6% fiber, 12% NFE, 1.5% calcium, 1.6% sodium, 1.5% phosphorous and sufficient amount of essential vitamins was administered to the larvae. Larvae were randomly distributed into 45 plastic tanks in a flow-through system at a density of 500 fish per tank. Fifteen fries were randomly selected from each holding tank and measurements on weight and length collected daily. Time series analysis and regression analysis were applied in the study. It was found that the length and weight of post larvae fed on mixed zooplankton was consistently lower than the other treatments. The length and weight of the fish fed on the three feed types were successfully modeled and forecasts made for future five periods while the relationship between length and weight was found to be significant on a linear regression model. This certainly adds value as the weight of post larvae catfish is measure with less difficulty and without causing injury or stress to the fish than measurement of length.

In the current study, data on nutritional composition and cost of conventional and non-conventional fish feed ingredients were gathered, a spreadsheet was created to bank the data. Four fish feeds were formulated and produced using three conventional fish feed formulation methods namely Pearson’s Square feed formulation method and two other conventional fish feed softwares, WINFEEDTM, ALLIXTM and a developed software (FUTA AQUAFEEDAPP); the software was developed using data analytical tools: simple harmonic equation, linear programming and stochastic programming techniques. The nutrient composition of the four diets were evaluated in the laboratory. The result of the proximate analyses indicated that the four diets met the crude protein requirements for African Catfish fingerlings, the values ranged from 40.68±0.62 (Pearson square) to 40.98±0.86 (ALLIX). There were no significant differences in the moisture content, crude protein, crude fibre, crude lipid and NFE across all treatments, however there was significant difference in the ash content across the four diets. The result of the cost assessment across the four treatments were significantly different, it revealed that AQUAFEED had the lowest investment cost ($1/Kg) when compared with the three other treatments, while Pearson Square had the highest investment cost ($1.5/kg) due to the high inclusion of fishmeal in the diet.

Objective: this study focused on the effect of a local feed supplement with synthetic amino acids (methionine and lysine) on the survival and growth of Clarias gariepinus fry in happas. Study Design: the study took place at the DJOKWE aquaculture farm located in the Cameroon Littoral Region, Moungo Department, Nkongsamba 1st District. Methodology: Six (06) local T0- diets without synthetic amino acid negative control, T0+ coppens imported feed positive control, T1 (L1.5/M1) containing 1.5% lysine and 1% methionine, T2 (L1, 5/M1.5) containing 1.5% lysine and 1.5% methionine, T3 (M1/L2) containing 1% methionine and 2% lysine, T4 (M1/L2.5) containing 1% methionine and 2.5% lysine were tested in triplicate on 540 fry of 10± 3.1g distributed in 18 happas of 0.5 m2. The fish were fed 3 times per day at a rate of 8% of the ichthyo biomass. Every 14 days, zootechnical parameters were evaluated. Results: depending on the level of supplementation, the survival rate was higher for the T0+ coppens treatment, 96.66%, and lower for T4 (M1/L2.5) supplemented with 1% methionine and 2.5% of lysine with 80%. The significantly highest average weight gain (p<0.05) was recorded with the T0+coppens treatment (89.67±1.52g) compared to the T1 (L1.5/M1) and low (66. 33 ±00g) compared to treatment T3 (M1/L2). The specific growth rate was higher (p˃0.05) or (2.83%±0.16g/d) with T2(L1.5/M1.5) and lower (0.78%±0 .02%g/d) for T0+ coppens. As for the condition factor K, it is significantly higher for the T0+coppens treatment (0.46%±0.030) and lower for the T4 treatment (0.29±0.023). Conclusion: the incorporation of 5% of black soldier fly larva into local feed supplemented with 1.5% lysine and 1% methionine makes it possible to improve the survival of Clarias gariepinus fry but also their growth as well as the production cost.

The study assessed the best immersion period and concentrations of the Cape gooseberry root Physalis peruviana that can efficiently remove egg adhesiveness of Clarias gariepinus. One male and one female C. gariepinus brood stock weighing 1.0 kg and 1.3 kg respectively, were used for the experiment. Three different concentrations (0.5%, 1%, and 2%) of tannin extract from Cape gooseberry root were used. Tannic acid (0.75g) diluted in 1 litre of water was used as reference de-adhesion agent, while water was used as control. The fish eggs were rinsed with the solutions at different durations of 0.5, 1 and 2 minutes. Each concentration and rinsing time was recorded in triplicates. Data generated were subjected to Univariate Analysis of Variance Test, and third order Polynomial regression analysis was then used to determine the best concentration and immersion period that neutralizes adhesiveness in eggs of C. gariepinus. Results of the study showed that there were no significant differences (p≤0.05) in the non-adhesive eggs and hatching of eggs immersed in tannin extract from Cape gooseberry root and Tannic acid solution but significantly different from the control. Therefore, this study showed that tannin extract from Cape gooseberry root at 1% concentration and 1 minute immersion period is more efficient for egg adhesion and increase hatching in C. gariepinus.

The cultivation of multilevel floating net cages (MFNC) systems is believed to be able to increase production capacity without increasing the horizontal area of the cultivation area. Research on the effect of using MFNC on the growth and health performance of Spiny lobsters and Snubnose pompano has never existed, so a study was conducted with the aim of comparing the growth and health performance of spiny lobsters and Snubnose pompano in floating net cage (FNC) and MFNC cultivation systems. The research method used was a field experiment with a comparative analysis of spiny lobsters and Snubnose pompano cultivation with different cultivation systems, namely the MFNC and FNC systems with 3 replications. The rearing lasted for 2 months and was fed trash fish as much as 5% of the biomass every day. Parameters of spiny lobsters and Snubnose pompano growth performance observed included weight growth, carapace length growth, total length growth, and specific growth rate. The health status of spiny lobsters observed quantitatively was the total hemocytes counts and hemolymph glucose levels, and Snubnose pompano by counting erythrocytes and blood leukocytes. The results showed that there was no difference in growth performance, survival and health status of spiny lobsters and Snubnose pompano reared using MFNC and FNC systems based on paired two sample for means, because p value > 0.05 for all growth parameters survival and health status. Thus, the use of a multilevel floating net cage system in lobster cultivation can increase FNC productivity and be efficient in optimal space utilization and does not affect water quality, especially the parameters of temperature, pH, dissolved oxygen and salinity. There were no significant differences in the growth performance, survival, and health status of lobsters and Snubnose pompano when reared using the MFNC and FNC cultivation systems.

This research aims to treat vaname shrimp disease infected with bacteriaVibrio parahaemolyticus. In this research, we used Completely Randomized Design (CRD) 4 treatments and 3 replications. The treatment being tested was the treatment of vaname shrimp disease by soaking in basil (O. basilicum) leaf extract with different concentrations, namely: Treatment A (0 mg/ml), treatment B (1.56 mg/ml), treatment C (3.12 mg/ml) and treatment D (12.5 mg/ml). The parameter observed was the number of bacterial coloniesV. parahaemolyticus maintenance media and in the hepatopancreas of vaname shrimp. Apart from that, observations were made on the survival rate of vaname shrimp and water quality parameters. The research results found that the best concentration in the treatment of diseaseV. parahaemolyticus in vaname shrimp at a concentration of 12.5 mg/ml with the lowest number of bacterial colonies in the rearing media, namely 1.20 x 102 CFU/ml. In the hepatopancreas of vaname shrimp, the lowest number of colonies was obtained at a treatment concentration of 12.5 mg/ml, namely 1.12 x 102 CFU/ml. The highest survival rate was obtained at a treatment concentration of 12.5 mg/ml of 86,67±5,77%. The range of water quality in research observations was obtained as follows salinity 28.72-29.05 ppt, temperature 26.71- 27.25OC, oxygen ranges from 5.72-7.81, pH 7.18-8.13 and ammonia 0.033-0.041ppm. Water quality during the research was in the optimal range for the life of vaname shrimp.

The study was done to evaluate moisture content and sensory properties of colored and non-colored noodles incorporated with different amount of fish (Silver carp, Hypophthalmichthys molitrix) mince during storage at room temperature (30-35○C) in two types of packaging conditions (sealed polyethylene packet and vacuum sealed packet). In addition, proximate composition, cooking time, and water absorption capacity were also investigated at initial stage. Boiled fish mince was incorporated with wheat flour and spices to prepare eight different samples namely CN (without fish mince, colorless), CC (without fish mince, colored), S1N (25% fish mince, colorless), S1C (25% fish mince, colored) S2N (30% fish mince, colorless), S2C (30% fish mince, colored) and S3N (35% fish mince, colorless) and S3C (35% fish mince, colored). No significant change in the moisture content of colored and non-colored fish noodles was found but moisture, protein, and fat content rose significantly with the increment of added amount of fish mince in the noodles. A significant decreasing trend was observed in the moisture content of the samples stored in sealed polyethylene packets during the 305 days of storage period whereas the moisture content of all the samples packed in vacuum sealed packets witnessed a non-significant change for the storage of 360 days. The color, flavor and texture of the products were acceptable up to 305 days in sealed polyethylene packets and 360 days in vacuum sealed packets. Food color had no remarkable effect on proximate composition, cooking time, water absorption capacity, and sensory characteristics of prepared noodles. Colorless noodles containing 35% fish mince was preferred by the panelists. So, both colored and non-colored fish noodles prepared with fish mince (up to 35%) can be stored at room temperature (30-35○C) in both sealed polyethylene packets and vacuum sealed packets for at least 10 months with acceptable moisture content and sensory properties. Vacuum sealed packaging provided the products with better protection against moisture loss throughout the storage period.
