Abstract

The world finfish database reports that Indonesia has more than 3,647 species of marine fish in the finfish category. Fisheries statistical data divides marine fishery catches into 92 species categories. It is very possible for one species category to be composed of more than 15 different taxonomic species. This research aims to analyze the composition of kembung-mackerel species as representatives of the small pelagic group, including the composition of catches in the Purse Seine and the peak fishing season. A total of 15 specimens in the mackerel fish category were sampled to trace morphological and genetic characters (COI region DNA analysis). Other fish were also searched for local names and morphological characters. A total of 744 Purse Seine catch data were monitored from three TPIs in Lamongan: Kranji, Labuhan, and Lohgung between February to July 2023. At the same time, monthly data compilations were also collected from January 2018 to May 2023. The results of DNA analysis found four identified species often reported as mackerel fish, are: Rastrelliger brachysoma, R. faughni, Scomber australasicus, and Sarda orientalis. These results are in accordance with the morphological characters of the keel (caudal peduncle), inter-dorsal region (between the first and second fins), finlets, and combination of ornaments in the dorsal and ventral regions. All these characteristics make it different from other members within the Scombrid family. Mackerel as a whole constitutes 37.1±24.2% of the total catch after tongkol (little-tuna). The peak mackerel fishing season starts from April to July, preceding the peak tongkol fishing season which starts from October to February the following year. Knowledge about this season is often used as a basis by fishermen to change the size of fishing gear, in adaptation to environmental conditions.

Abstract

Understanding the natural bait preference of predatory fish, such as barramundi, plays a crucial role in improving capture efficiency. This knowledge also supports sustainable fisheries by optimizing bait selection for handline fishing and reducing reef damage by active gear where barramundi species commonly live. This study examines the response of barramundi to various types of natural bait and investigates whether body size plays a significant role in this response. Predatory fish are divided into three different sizes (9, 13, and 15 cm total length), with each size having nine replicates. Fishing behavior and response to baits were divided into four phases: arousal, searching, finding, and uptake. Kinovea computer software (www.kinovea.org) was used to identify each phase with visual support from iVcam. The experiment was designed using a 54 L aquarium filled with saline water of 32 ppt. Data were analyzed using one-way ANOVA in SPSS version 26. When significant differences (p<0.05) were found, Tukey's post hoc test was performed. Bait from trash fish and shrimps did not show significant differences (p>0.05). Worms provided the fewest responses on times and behavior. Body size did not significantly affect behavioral responses or response times (p > 0.05). In conclusion, bait type significantly influenced barramundi's responses, with worms eliciting a significantly slower response compared to shrimp and trash fish, which were equally effective.

Abstract

Glass strain carp (Cyprinus carpio) is highly demanded by farmers due to its delicious, dense meat and fewer spines. To meet the increasing demand for carp, it is necessary to improve the efficiency of aquaculture. The season is known to stimulate one hormone production. The purpose of this study was to determine the effect of season (rainy and dry seasons) on reproductive hormones (follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone and estrogen, and interstitial cell-stimulating hormone)) in C. carpio glass strain. Idi research was conducted using the descriptive method by rearing fish in different seasons (rainy season and dry season). The results showed that the reproductive hormone of C. carpio strain glass increased during the rainy season. During the rainy season, changes in the environment and water flow patterns are detected by the fish's sensory system. The results showed that the highest hormones in a row were: ICSH hormone (12.82 pg/mL), FSH hormone (male: 3.73 ng/mL; female: 12.10 ng/mL), LH hormone (12.48 MIU/ml), testosterone hormone (9.27 ng/mL) and estrogen hormone (21.84 ng/mL). Further research is needed to observe the growth and abnormality of fish larvae produced in different seasons.

Abstract

Spirulina platensis is a highly nutritious cyanobacterial microalga. This microalga is rich in protein, vitamins, minerals and antioxidants. The use of media and cultivation methods that are not appropriate can affect the nutritional content of this microalgae. This study aims to evaluate the effect of urea on growth, biomass production, nutrient content and pigments of S. platensis on an outdoor scale. Technical media such as urea are used instead of nitrate in standard media (zarrouk). This study used four treatments with three replications. The treatments used were different doses of urea, namely 0.1 g/L, 0.4 g/L, 0.7 g/L, and 1 g/L. The results showed that the use of urea affected the growth and nutritional content of S. platensis. The use 0.4 g/L urea producued comparable results than that of nitrate as nitrogen source. However, phycocyanin content was still lower than nitrate-based media. Inconclusion that urea was potential alterative nitrogen source for spirulina cultivation.

Abstract

Quality feed in aquaculture is very important to increase the growth and health of fish. Low feed efficiency can be overcome by feed supplementation using catalytic enzymes. One of the enzymes that can stimulate digestion is protease in red ginger plants. The protease enzyme in red ginger plants plays a role in breaking peptide bonds in place of carboxyl groups so that peptides are formed from complex compounds into simpler compounds. This study aims to determine the profile of amino acids and proximate in feed given red ginger enzymes. This research uses descriptive method. The feed sample used was commercial feed with 4 treatments namely Control (without red ginger enzyme), treatment A (1%), treatment B (3%), and treatment C (5%). The analyzes carried out included red ginger enzyme extraction, protease enzyme purification, proximate and amino acid analysis of each type of feed. The results showed that the results of the SDS-Page analysis on the red ginger protease sample contained at 67.1 kDa. The results of the proximate analysis showed the highest value in feed containing 3% red ginger protease (B) with a percentage of 42.69%. The resulting amino acid content consists of 8 non-essential amino acids namely, L-serine, L-glutamic acid, L-alanine, L-arginine, glycine, L-aspartic acid, L-tyrosine and L-proline. While the essential amino acids consist of 7 types of amino acids namely, L-Phenylalani, L-Isoleucine, L-Valine, L-Lysine, L-Leucine, L-Threonine and L-Histidine. The best type of feed is feed B, which is feed with the addition of 3% red ginger protease.

Abstract

Tilapia (Oreochromis niloticus) is a freshwater fish that has high economic value and potential to be cultivated. The problem that often arises in tilapia cultivation is the lack of optimal use of the feed given. The purpose of this research was to find out blood profile of tilapia during culture period. The method used was a completely randomized design (CRD) with five treatments and every treatment with four replications. This study used 240 Tilapia with average weight of 15 g. The stocking density of the aquaria is 15 fish. Test feed in this study is the form of dry pellets consisting combination of GAA levels, protein content (25% dry matter bases), and source of protein (fish meal and non-fishmeal). During the cultured period of 70 days, fish fed by formula diet of 3% biomass per day. Sampling for blood profile tested of erythrocytes, leukocytes, and hematocrit is carried out after the research. The water quality of temperature, pH, and DO were daily monitoring. The combination treatment of guanidino acetic acid (GAA) levels with different protein sources (fishmeal and non-fishmeal) had a significant effect on total erythrocyte of tilapia, but did not have significant differences between treatments on total leukosyte and hematocrit. Treatment with 1.2 g/kg GAA, fish meal protein source was the best treatment in this research.

Abstract

The drying process is often a problem in maintaining the stability of probiotics and the quality of microcapsules in the processing of synbiotic microencapsulation. This study aims to optimize the temperature and drying time to maintain the core material's stability and the microcapsules' quality. The research design in this study was a completely randomized design with two factorials, namely drying temperature (30°C, 35°C, and 40°C) and drying time (2, 2.5, and 3 hours). The results showed that the highest viability and efficiency values ​​were obtained in the drying process at 40°C for 2 hours, which were 9.29 log CFU/mL and 98.10%. In addition, the water content and gel strength of the microcapsules obtained also showed optimal conditions. Based on the results obtained, it can be concluded that the drying process at 40°C for 2 hours is the best treatment, with the highest viability and EE values ​​and low water content values.
