Abstract

The spawning of striped catfish which is very dependent on the season and environmental conditions results in the unavailability of mature gonad broodstock during the dry season. The alternative that is often done is by biological stimulation using the ovaprim hormone and laserpuncture technology. The purpose of this study was to determine the effect of giving the ovaprim hormone, laserpuncture induction and a combination of the two on the speed of spawning time and the fecundity value of Striped catfish. This study used an experimental method with a completely randomized design with 3 treatments and 6 replications. The results of this study were the average spawning time for broodstock treated with laserpuncture and ovaprim hormone and the fecundity value was significantly different from the other treatments (p<0.05). Based on the results of the study, it can be concluded that the combination of 0.5 ml/kg of ovaprim hormone and laser puncture at a dose of 0.5 J/cm2 for 32.66 seconds can speed up the spawning time and fecundity of striped catfish.

Abstract

Kuhli loach (Pangio kuhlii) a popular ornamental freshwater fish species with economic potential, originating from Sumatra, Kalimantan, Java, and Malaysia. The kuhli loach's appeal lies in its vibrant colors and distinctive eel-like body. This study aims to explores the sexual primary and secondary characteristics of the kuhli loach. Conducted at Universitas Airlangga in Banyuwangi, Indonesia, the study involved a thorough analysis of 50 kuhli loaches, evenly split between males and females. Morphological observations revealed significant differences (p < 0.05), such as the elongated body and expanded abdominal region in females, suggesting adaptations for reproduction. Internal examinations, including peritoneal dissections and histological analysis, unveiled distinct stages of spermatogenesis in males and ovarian development in females, providing insights into the reproductive cycle. Meristic and morphometric analyses identified noteworthy differences in pectoral fin rays, suggesting potential roles in reproductive behavior, while other traits exhibited similarity between genders. This study contributes to the understanding of kuhli loach ecology and reproductive biology, highlighting the importance of addressing sustainability concerns arising from the continuous exploitation of wild populations. This study serves as a foundational step towards advancing reproductive improvement in fish and supports the conservation of this unique ornamental fish species, with implications for aquaculture practices and economic considerations.

Abstract

Albumin is a plasma protein that consists of a single polypeptide chain and is used to accelerate the recovery of split/damaged cell tissue. Albumin is produced from human blood in the form of human serum albumin (HSA) which is fulfilled through imports at a relatively expensive price. The alternative albumin is needed to get the cheaper albumin but has the same clinical aspects, such as albumin from the scad fish (Decapterus ruselli). The purpose of this study is to determine the effect of different steaming temperatures on the albumin levels of scad fish (Decapterus ruselli) and get the optimal steaming temperature used to obtain albumin levels from scad fish (Decapterus ruselli). This research was conducted by the Completely Randomized Design (CRD) method which consists of 4 different steaming temperature treatments with 5 replications. The parameters observed were albumin content, protein content, and yield. The parameters were tested using One Way Analysis of Variance (ANOVA) followed by the Duncan Multiple Range Test. The results of this study showed that the treatment of different steaming temperatures had a significant effect (p<0.05) on the albumin levels and percentage of protein content. The optimum steaming temperature to obtain the highest albumin content from scad fish species Decapterus ruselli is 35℃ with an albumin content of 0.1394 g/L.

Abstract

The annual need for Artemia in Indonesia reaches 40-60 tons, but up to now 100% of this need is still imported. Various efforts have been made to produce Artemia cysts, but the main obstacle in cultivating Artemia to produce cysts is the availability of natural food, namely phytoplankton which can survive in high salinity. The use of organic materials such as bran can be a solution for feeding and can increase the density of Artemia, but excessive use of bran suspension in Artemia cultivation ponds can trigger a decrease in the quality of the water for the growth of Artemia. This research was conducted to determine the optimal concentration of bran feed for the growth and development of Artemia salina without compromising the water quality of the cultivation. The Artemia feed used in this study was a bran suspension enriched with lemuru fish oil (12 ml/L bran suspension). The bran feed concentration treatments in this study were 5 treatments sequentially, namely P1 to P5 with feed concentrations of 11, 18, 26.34, and 41 mg/L. Artemia salina cultivation in this study was carried out at an initial density of 50 ind/L with a salinity of 30 pptl. The research results showed that cultivating Artemia salina using bran suspension feed with different concentrations had an effect on the growth and development of Artemia salina. The best growth and development of Artemia results from cultivation using bran suspension feed with a concentration of 41 mg/L.

Abstract

The cultivation of vaname shrimp produces waste with a high nutrient content. This waste can be used as fertilizer in microalgae culture like Sprulina platensis. However, the N / P ratio in shrimp culture waste is low, namely 5.5: 1, while the need for growth of blue-green algae ranges from 10:1 - 16:1. Therefore, it is necessary to regulate the N: P ratio in shrimp culture waste to match the needs of S. platensis. The purpose of this study was to determine the effect of different N / P ratios on shrimp culture waste fertilizer on the growth of S. plantesis. This study used a Completely Randomized Design (CRD) which was divided into 6 treatments with 3 replications, as P0: Walne fertilizer (N / P ratio 17: 1), P1: shrimp culture waste fertilizer enriched with urea (N / P ratio 5,5: 1), P2 with N/P ratio of 10.5: 1, P3 with N/P ratio of 15.5: 1, P4 with N/P ratio of 20.5: 1 and P5 with N/P ratio 25.5: 1. The parameters observed were density and growth rate of S. platensis and water quality namely: temperature, salinity, and pH. The data obtained were processed using Analysis of Variance (ANOVA) and continued with Duncan's multiple range test. The results of this study indicate that the application of shrimp culture waste fertilizer with different N/P ratios affect the population and growth rate of S. platensis. Shrimp culture waste fertilizer with a N: P ratio of 15.5: 1 (P3) is the best treatment for the growth of S. platensis because it produces the highest population and growth rate compared to the other treatments.

Abstract

Moina macrocopa is a natural food that has the potential for freshwater fish seeds, because of its high nutritional value, easy to digest and has a fast, fast breeding, and has a size that is in accordance with the fish's mouth opening. Problems in the use of M. macrocopa as natural food are constrained by the availability of M. macrocopa both from nature and from cultivation. Population density in M. macrocopa cultivation varies due to different quality of food used. The needs of M. macrocopa as natural food can be met if the quality and quantity of feed used optimally support population growth. This study aims to determine the effect of lemuru fish oil concentration in bran suspension fermentation on fecundity and offspring production of M. macrocopa. This study used a completely randomized design (CRD) consisting of five treatments three replications, namely: control treatment (0 mg/L lemuru fish oil, 100 gram bran), P1 (4 mg/L lemuru fish oil, 100 gram bran), P2 (lemuru fish oil 5 mg/L, 100 gram bran ), P3 (lemuru fish oil 6 mg/L, 100 gram bran), P4 (7 mg/L lemuru fish oil, 100 grams), and P5 (8 mg/L lemuru fish oil, 100 gram bran ).The parameters observed were fecundity and child production per parent and water quality. Data analysis used the Analysis of Variance test followed by Duncan's multiple test. The results showed that the cultivation of M. macrocopa using different bran suspension feed with supplemented lemuru fish oil affected the fecundity and production of children per M. macrocopa parent. The concentration of lemuru fish oil of 6 mg/L in the feed resulted in a fecundity of 24,00±2,00 eggs/parent and child production is 20,33±1,52 ind/parent.

Abstract

Textile waste consists of insoluble solid particles, salts, dyes and heavy metals and is very difficult to degrade. Chitin derived from shrimp waste has the potential to overcome textile waste in chitin that causes environmental pollution through more economical absorption and easily available raw materials. Factors that improve adsorption performance include pH and temperature. This study was conducted to determine the effect of temperature, pH, and a combination of temperature and pH treatments on the ability of chitin to adsorb textile dye waste. The parameters observed were temperature, pH, combination of temperature and pH, functional groups (FTIR), chitin structure (SEM), and heavy metal test (AAS). Data analysis of statistical test results using two-way Analysis of Variance (ANOVA) followed by Duncan's further test. The ANOVA test results showed that the incubation treatment of temperature, pH, and a combination of different temperature and pH treatments resulted in (p < 0.05). This shows that incubation temperature and pH have an effect (significantly different) on the adsorption of chitin as an adsorbent on dyes. The results of Duncan's test showed that the best chitin adsorption was obtained in temperature incubation at 50°C (A3), incubation at pH 3 (B1), and the best combination adsorption at 50°C and pH 3 of 1,091±0.007a ppm.

Abstract

Carbon dioxide emissions from burning fuel oil have been increasing, resulting in increasingly severe climate change. The use of microalgae as raw materials for biofuel production is an environmentally friendly alternative. Microalgae Chlorella sp. can be sustainably converted into alternative biofuels. Fishery liquid waste, such as that resulting from fish farming and fish processing, can be used as a nutrient medium for microalgae. This study aimed to analyze biomass production from Chlorella sp. using fishery waste in an algae reactor. The working principle of fisheries wastewater processing is related to microalgae in the reactor. The surface of the media forms a biological layer that breaks down organic compounds in the air, thereby reducing the organic content. The compounds resulting from metabolic processes are in the form of solids and gases. The results show that the bioethanol produced from the thermostat Chlorella sp. with fishery waste media can produce 20,000 L/ha. Microalgae contain approximately 20-50% dry weight of carbohydrates, which can be converted into bioethanol. Chlorella sp. can reduce chemical oxygen demand and ammonia by up to 70% by converting carbon dioxide into carbohydrates, fats, and proteins. The application of bioconversion to all companies in the fisheries sector will provide benefits and help the government reduce fossil fuel subsidies.
