Abstract

Highlight Research Each species of microalga has a preferable nitrogen source for their optimal growth. The nitrogen sources in the grown media affected the growth rate and biochemical composition of Chlorella FNUB01. (NH2)2CO (urea) was found to be the best alternative nitrogen source for Chlorella FNUB01. For producing 1 g of Chlorella FNUB01, the use of urea reduced the cost of medium by 72.6%. Abstract Chlorella sp. is a potential microalgae species to be produced commercially for feed, growth accelerator, and immuno-modulator in fish and shrimp culture. This study aimed to evaluate the various nitrogen sources on the growth, biomass production, and biochemical composition of Chlorella sp. FNUB01. The nitrogen sources used in this study were urea (NH2)2CO, potassium nitrate (KNO3), and ammonium nitrate (NH4NO3). Sodium nitrate (NaNO3) was used as a control as it is a part of the commercial medium BG-11. Generally, the sources of nitrogen in the media affected the growth and chemical composition of Chlorella sp. FNUB01. This green microalga grew better in the urea-containing medium which accounted for 1.5 times the concentration of that cultured in BG-11 (40 x106 cells. mL-1). Meanwhile, this microalgae species experienced the lowest growth when cultured in NH4NO3-containing medium. The biomass productivity of Chlorella sp. FNUB01 cultured in urea (0.93 g.L-1) was comparable to those grown with NaNO3 as the N source. A similar pattern was recorded for protein, chlorophyll, and carotenoid content as these biochemical contents were affected by N availability in the medium. Urea was an alternative low-cost N source for the culture of Chlorella sp. FNUB01. Replacement of NaNO3 with urea could reduce the cost of the medium by 72.6%.

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

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 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.
