Abstract

The present study was conducted to determine the effect of using turmeric extract (Curcuma zedoaria) on non specific immune of grouper (Epinephelus fuscoguttatus). During the study, fish were fed a diet containing 0, 0.5, 1.0, 2.5 g extract/kg feed twice a day for 14 days. Observations of non-specific immune parameters such as respiratory burst activity, chemiluminescent response, phagocytic activity, superoxidase dismutase (SOD) and lysozyme activity were sampled at 0, 1, 2, 4, 7 and 14 days. The results showed that fish fed C. zedoaria with 0.5 g/kg feed affected non-specific immune responses, and showed significant effect in the short term. On contrary, for long-term administration causes a decrease and inhibition of non-specific cellular defense activity. Thus, this study concluded that the administration of turmeric extract added to the feed can act as an immunostimulant and increase the non-specific immune response in grouper (E. fuscoguttatus).

Abstract

Corn starch is a source of carbohydrates for most cultivated fish, includes rabbitfish as one of the herbivores with high economic value. Therefore, rabbitfish requires cheaper carbohydrate sources to have a profitable business in its cultivation. This study was aimed to determine the substitution of corn starch with Sargassum sp. starch in the diet on the growth, relative feed intake, FCR and nutrient retention of rabbitfish. The average weight of rabbitfish used was 51.76±0.12 g/fish. Rabbitfish were cultivated in small net cages (1x1x1.5m) with a stocking density of 20 fish/net cage for 90 days reared. This study used an experimental method with a Completely Randomized Design (CRD). Corn starch (CM) substitution with Sargassum sp. starch (SM) by 0% (A), 21% (B), 42% (C), 63% (D) and 83% (E) used as the treatments with three replicates each. The measured parameters were weight gain (WG), relative growth (RG), relative feed intake (RFI), feed conversion ratio (FCR), protein retention (PR), energy retention (ER), and condition factor (CF). Data were analyzed using the analysis of variance (ANOVA) and Tuckey’s test. The results showed that the lowest FCR in treatment A had no significant effect with treatment B but was significantly different from treatments C, D and E. The WG, RG, RP and CF parameters had the same values at all levels of CM substitution with SM, while RFI and FCR increased with the increasing CM substitution by SM. It also indicated that CM in the rabbitfish diet could be substituted with SM by 83%.

Abstract

This feeding experiment was performed to determine the effects of Myrmecodia pendens bulb extract (MBE) supplementation in fish feed on the growth, survival, and hemato-biochemical profile of Clarias gariepinus. A group of fish was fed with 0.25; 0.50; 1.0; 2.0% MBE and compared to control group (without MBE) for 75 days observation. At the end of feeding trial, growth parameters, hematological profile such as red blood cells (RBC), white blood cells (WBC), Hemoglobin (Hb), Hematocrit (Htc), differential leukocyte, blood plasma biochemistry (glucose, total albumin, cholesterol, and triglyceride), the hepatosomatic (HSI) and intestinal somatic index (ISI) were measured. Survival of all fish was also counted every two weeks. Supplementation MBE above 0.25% resulted significantly higher final biomass weight (FBW), body weight gain (BWG), daily weight gain (DWG), and average weekly gain (AWG). Meanwhile, fish group fed dietary MBE above 1.0% had significantly higher specific growth rate (SGR) (3.32±0.15) than other groups. Fish fed 1.0% of MBE also showed better value of feed conversion ratio (FCR) (1.13±0.03), Hb, and HSI compared to others group. Survival, neutrophil, monocyte, and ISI of all groups was not affected by any concentration of MBE supplementation. Dietary MBE above 0.5% enhanced RBC, WBC, Hematocrit, platelet (PLT), lymphocyte, blood plasma biochemistry such as glucose, total albumin, and triglyceride. Cholesterol of fish fed MBE in the diet showed incrementally enhanced. Present finding suggested that 1.0% MBE in the diet of Clarias gariepinus is recommended to enhance growth, survival, and blood profiles

Abstract

The mangrove plants has long been utilized as traditional medicinal ingredients for treatments of various diseases in favour of bioactive components from its secondary metabolites. Secondary metabolites from mangroves could act as an antioxidant to prevent oxidative stress. Mangrove may contain endophyte fungi in its tissues that are capable of producing secondary metabolites. In theory, endophyte fungi isolated from a plant can produce secondary metabolites similar to those of the original plants or even in relatively high numbers. In this research, mangrove species Avicennia marina was sampled from Blanakan, Subang District, West Java. Endophyte fungi were isolated from the mangrove roots that had been obtained. The experimental method was used to test antioxidant activitiy using DPPH (1,1-diphenyl-2-picrylhidrazyl) method and phytochemical content, with three replicates for each tests. Fungal isolates were coded according to the distance of the roots from the main mangrove tree, namely STAD and STAJ that represents “close” and “far” roots. Our results showed that the enviromental parameters, namely salinity, dissolved oxygen, and temperature meet the quality standards and mangrove life in the tropics. The A. marina type of substrate muddy soil and has a pH value, which did not meet the quality standards for mangrove waters. As for antioxidant activity, both extracts could reduce DPPH free radicals. Further determination of the IC50 value of the two extracts showed that the endophytic fungi STAD and STAJ had IC50 values of 97.8 ppm (classified as strong) and 822.56 ppm (classified as very weak) in the DPPH radical immersion method. Phytochemical test revealed that the two extracts of fungal isolates contain bioactive compounds, where flavonoids and alkaloids were identified in isolate STAD, whereas STAJ was positive for tannins and alkaloids content.

Abstract

Maggot (Black soldier fly larvae) as an alternative source of protein on feed can increase fish productivity. The research aims to study maggot flour as an alternative source of protein in feed on the growth, structure of the intestine organs and skeletal muscles of Mutiara catfish (Clarias gariepinus Burchell, 1822). The research used 144 Mutiara catfish that were kept for 21 days. The research used a completely randomized design consisting of 4 groups, namely 0% maggot in feed (Control), 25% maggot in feed (P1), 50% maggot in feed (P2), 75% maggot in feed (P3). The parameters consist of the growth, the structure of intestine and skeletal muscle of Mutiara catfish. Growth observations consist of measurements of the absolute length and weight of the fish. Intestine observations consisted of length and weight, as well as tissue structure consisting of villi height, crypt depth, villi / crypt ratio and villi area area. Skeletal muscle observations consist of muscle weight and tissue structure consisting of the diameter and area of muscle fibers. Data analysis was performed with one-way anova, followed by the Duncan Test. The results showed that 75% maggot feed gave significant results on absolute weight, structure of intestine and muscle organs compared to other treatments (P <0.05). The absolute length did not provide a significant difference between treatments (P> 0.05). The conclusion shows that 75% maggot feed can be used as an alternative source of feed protein because it can increase the growth, structure of the intestine organs and skeletal muscles of the Mutiara catfish.

Abstract

The aim of this study was to determine the PCB levels in the Atlantic Mackerel (Scomber scrombus) sourced from cold storage points in Benin City, Nigeria by GC analysis and its suitability for human consumption. The PCB concentrations (mg/kg) in S. scombrus ranged from 0.0183 for PCB 114 to 0.5542 for PCB 126 with a recorded total of 0.991 while the mean concentrations (mg/kg) of PCBs in S. scombrus by cold storage point ranged from 0.0111 for PCB 114 to 0.684 for PCB 126 both at the New Benin points, with no observed significant difference (P>0.05) in the mean concentrations of PCBs 126, 156 and 180 in fish between these points. The mean concentration (mg/kg) of PCBs in S. scombrus by month peaked in June with a value of 0.615 for PCB 126. However, there was no observed significant difference (P>0.05) in the mean concentrations of PCBs 114, 118, 138, 153, 156 and 180 in fish specimens between months. Essentially, data from the study revealed that the experimental fish species are suitable to eat by the consuming public as there was no glaring indication of immediate health hazard.

Abstract

The cost incurred in raising fish to table size in fish farming has been a major issue both to the farmers and the consumers at large. To address this concern this study assessed the growth performance of Clarias gariepinus fed varying inclusion levels of water melon (Citrullus lanatus) bark. A total of 120 samples with 0.75±0.209g mean weight and 3.9±0.31cm mean total length were acclimated in the laboratory for a period of 14 days during which they were fed to satiation twice daily. Subsequently, they were randomly assigned to the five treatments diets with replicate in each case at 12 fish per treatment; T1 with 00%, T2 with 25%,  T3 with 50%, T4 with 75% and T5 with 100% levels of inclusion as possible replacement for equal weight of soybeans. The set-up ran for 12 weeks and the growth parameters (lengths and weight) were determined on weekly basis. Weight gain and specific growth rate were calculated. The physico-chemical parameters of the test media were also determined on weekly basis according to standard methods. The data generated were subjected to one way analysis of variance. From the results: Treatments with 50% and 75% inclusion levels performed slightly better than the control in terms of weight gain. The highest weight obtained in T2 and T3 were 31.71±0.35g and 31.48±1.71g, respectively. Similarly, the optimum requirement of watermelon bark level in the formulation of practical diets for improved growth of C. garienpinus were 50% and 75% in terms of lengths. T2 and T3 had the highest total lengths with 19.05±0.35cmand 15.90±2.80cm, respectively; while the standard lengths in T2 and T3 were 13.50±0.35cmand 13.45±2.85, respectively. Hence, water melon bark can replace the more expensive soybean thereby reducing cost of production and curtail environmental filth and disposal problems associated with watermelon bark waste in Nigeria.

Abstract

Olive flounder (Paralichthys olivaceus) is the most popular consumption fish in South Korea. Korean consumes flounder as sashimi, spicy soup, stew and cutlet. Due to its popularity; Korean considers Olive flounder as the nation’s raw fish. Despite advanced aquaculture technique, modern facilities and massive production, fingerling size grading and abnormal sorting are conducted by traditional method. This study was conducted by observation. A group of 5 to 6 person worked meticulously to sort out abnormal fingerling and juvenile. Sorting is based on physical traits such as the shape and structure of head, jaw, operculum, fin, body; body coloration, pigmentation and length. Due to the exclusiveness and technicality of this profession, information and standard in grading and sorting has been lacking. This research provides the information about sorting criteria of Olive flounder juvenile and detail description of physical abnormalities being sorted out.

Abstract

The potential of freshwater fisheries in Bangka Regency, Bangka Belitung Province, is sufficient to support fisheries activities in this area. An activity that is quite prominent is catfish farming using swamps and tarpaulin ponds on limited land. In this study, the analysis of cultivation activities was carried out on the Bukit Dempo community group who became partners in the national community service activities, in cooperation with Universitas Airlangga and Bangka Belitung University. Characteristics of the pond using a combination of fixed nets with a net diameter of 0.5 cm. In the pond also found water plants in the form of water hyacinth which is expected to be able to make a symbiotic use of the organic material that has been left behind from feed and catfish waste. The cultivation system is classified as semi-intensive with a combination of commercial feed with high protein (31-33%).  The main problem in this cultivation system is low productivity and the lack of technology applied in an effort to increase production efficiency Furthermore, high production yields are marketed to Pangkal Pinang City and also to local areas around the Belinyu sub-district. Technical constraints include Motile Aeromonas Septicemia (MAS) due to the bacterium Aeromonas hydrophylla, which causes about 10% of mortality in commodities before harvest. There has been no treatment action in overcoming the disease, so it is necessary to be careful in avoiding death due to disease by observing catfish at the change of seasons.

Abstract

The research objective of this study was to determine the impact of feed enrichment using Moringa leaf meal and shrimp meal on the growth performance of Tilapia. The initial weight of experimental fish was 6.10 ± 0.55 g/ head. The treatments given were Treatment A (feed without Moringa leaf meal and shrimp meal), Treatment B (commercial feed + 20% shrimp flour), Treatment C (commercial feed + 10% Moringa leaf meal + 20% shrimp meal), and Treatment D (commercial feed + 20% Moringa leaf meal + 20% shrimp meal). In total, there were 4 treatments with 3 replications each. Fish rearing lasted for 40 days. The results showed that the treatments had no effect on amount of feed consumption, protein efficiency ratio, specific growth rate, feed efficiency, survival rate, coefficient of variation and hepatosomatic index (p>0,05), but had an effect on the amount of protein consumption and body protein (p<0, 05). In conclusion, the enrichment of feed containing Moringa leaf meal and shrimp meal had no effect on the growth performance of Tilapia.
