Abstract

Vannamei shrimp (Litopenaeus vannamei) is a brackish water commodity that is currently in great demand and is a leading producer of the aquaculture sector in Indonesia. This is because some of the advantages possessed by the vannamei shrimp, among others, can be maintained with a high stocking density, rapid growth, has a high resistance to disease and environmental changes. The mating process occurs through four stages, namely approach, pursuit, pride, and mating. This process can be known by looking at the behavior of the male parent who swims to follow the female parent. They both looked like a chase. Then the male parent swims parallel to the female and turns her body towards the female shrimp's belly. After that, the male grabs the female and releases sperm that attach to the thellycum. In the maintenance of larvae that must be considered is the management of water quality and feed management. This is because water is a living medium for aquatic organisms, so it determines the survival of larvae. During the period of high maintenance and market, demand continues to increase where the shrimp farming process includes the hatchery stage to enlargement. Vannamei shrimp hatchery activities are inseparable from the availability of quality fry

Abstract

This study aimed to assess the quality of seaweed by analyzing its carrageenan content, water content, and growth rate. The research was conducted in the waters of Liang Village and Jayabakti Village for 45 days, with observation periods every 15 days. Carrageenan examination was carried out at the Pharmacy Laboratory of Sam Ratulangi University, while the water content was determined at the THP Laboratory of the same university. Growth measurements were conducted at 0, 15, 30, and 45 days in both locations. The results showed that the concentration of carrageenan in seaweed from Jayabakti Village was 39.81%, while in Liang Village it was 35.88%. The percentage of seaweed water in Liang Village was 9.3%, while in Jayabakti it was 27.0%. In addition, there was no significant difference in seaweed growth between the two water sites (P>0.05). The average difference in seaweed growth between Jayabakti Village and Liang Village on days 15, 30, and 45 was 1.5, 0.5, and 16.3, respectively. The daily weight gain rate of seaweed on day 15 was 5.55% in Jayabakti Village Waters and 5.50% in Liang Village Waters. On the 30th day, the daily weight gain of seaweed in Jayabakti Village Waters and Liang Village was 4.88% and 4.89%, respectively. On the 45th day of the rearing period, seaweed in Jayabakti Village Waters experienced a weight gain of 4.16%, while seaweed in Liang Village experienced a weight gain of 4.22%. The findings showed that the carrageenan test, conducted by assessing water content, indicated that the quality of seaweed in the waters of Liang Village was superior to that of Jayabakti Village.

Abstract

Water quality is a major factor in the survival of white snapper. In the process of successfully producing white snapper, it is necessary to monitor the water quality in the spawning tank so that it can determine the optimal water quality and its effect on the hatching power of snapper eggs. The purpose of this study was to see the correlation of water quality parameters with egg hatching, and to determine the relationship between length and weight in White Snapper. The analysis method used is the parametric statistical method with the analysis tool used, namely the SPSS statistical application 26. The analysis used is a simple linear regression test, and a correlation test between water quality and egg hatching power. The results of the study showed that the growth pattern was more dominant in increasing the length of white snapper, while the results of the Pearson correlation test showed that temperature and salinity suitability greatly influenced the number of white snapper eggs that hatched.

Abstract

Penelitian ini dilakukan untuk melihat perbedaan lama waktu pematangan gonad dari udang vaname yang di ablasi dan tidak di ablasi. Penelitian ini dilaksanakan di instalasi Pembenihan Udang di Balai Perikanan Budidaya Air Payau (BPBAP) Situbondo, Jawa Timur. Karakteristik induk udang yang baik adalah udang jantan dan betina memiliki karakteristik reproduksi yang sangat bagus. Spermatofora jantan berkembang baik dan berwarna putih mutiara dan udang betina matang secara seksual dan menunjukkan perkembangan ovarium yang alami. Induk berasal hasil pemuliaan Multipication Broodstock Center (MBC) dengan bobot tubuh sebesar 30-35 g (jantan) dan 40-45 g (betina). Induk diberikan kombinasi tiga jenis pakan selama masa pemeliharaan dengan frekuensi pemberian 4 kali sehari sebesar 40% dari biomassa yakni pukul 07.00, 11.00, 15.00 dan 19.00. Proses ablasi dilakukan pada pagi hari. Proses ablasi yang dilakukan adalah dengan cara memegang induk betina secara perlahan-lahan dan hati-hati sehingga udang tidak merontaronta dengan cara melipat ekor udang ke arah dalam secara perlahan. Lalu setelah itu dilakukan pemotongan tangkai mata menggunakan gunting arteri yang telah dipanaskan. Pemotongan tangkai mata dapat dilakukan pada bagian kanan ataupun kiri sesuai kondisi mata induk. Setelah di ablasi, induk udang diamati tingkat kematian untuk meyakinkan ketersediaan induk yang akan digunakan untuk pengamatan tingkat kematangan gonad. Tingkat kematangan gonad udang vaname menunjukkan ada perbedaan pada lama hari inkubasi untuk perlakuan ablasi dan non-ablasi. Periode waktu untuk perkembangan TKG udang yang di ablasi antara 0-12 hari sedangkan 0-22 hari untuk yang tidak di ablasi.This study was conducted to see the time difference in the gonad maturation time period of ablated and non-ablated Vaname shrimp. This study was conducted at the Shrimp Hatchery Instalansi at the Brackish Water Aquaculture Center (BPBAP) Situbondo, East Java. The broodstock originated from the Multipication Broodstock Center (MBC), where they were bred for body weights of 30-35 g for males and 40-45 g for females. During the rearing period, the broodstock received a combination of three types of feed four times a day at 40% of biomass, at 07:00, 11:00, 15:00, and 19:00. We carried out the ablation process in the morning. We perform the ablation process by gently folding the shrimp's tail inward and holding the female parent slowly and carefully to prevent it from struggling. Next, use heated artery scissors to cut the eye stalk. Depending on the condition of the parent's eye, you can cut the eye stalk on either the right or left side. We observed the mortality of shrimp broodstock after ablation to ensure its availability for gonadal maturity observations. The difference in the number of days needed for ablation and non-ablation treatments was seen in the vanamei shrimp's gonadal maturity level. The time period for the development of TKG in ablated shrimp is between 0 and 12 days, while 0 and 22 days for non-ablated shrimp.

Abstract

Chlorella sorokiniana is a microalgae with an outstanding nutritional profile and numerous therapeutic substances that can be used as an immunostimulant, including in aquaculture. This research aimed to investigate and characterize peptides isolated from C. sorokiniana protein using TCA digestion and hydrolyzed enzymatically with trypsin. Peptides were then subsequently identified using Tandem LC-MS/MS and Mascot Distiller. Results showed that the percentage of pure protein yield following TCA digestion was 54.66%, and 12 peptides with lengths ranging from 7 to 23 sequences were discovered after trypsin digestion. These peptides originated from various enzymes and chloroplast proteins, including protein synthesis elongation factor TU, photosystem I iron-sulfur center, photosystem II 43 kDa, Ycf4, ATP-dependent zinc metalloprotease FtsH homolog, nitrate reductase, chloroplastic glucose-6-phospate dehydrogenase, and ATP synthase CF1 alpha chain. These findings demonstrated that C. sorokiniana might serve as a source of immunostimulant peptides and proteins, particularly for aquaculture biota.

Abstract

The fisheries sector is one sector that has great potential in improving the economy. To increase the income of fish cultivators, farmers need to manage their business results better before they were marketed or sold. The welfare level of fish farmers was still low, this is not because the selling price of fish is low, nor is it because of the large number of imported fish, but rather due to the government's lack of attention to the fishery sector, especially freshwater fisheries. This study used a descriptive method, which was conducted in the Lima Puluh Kota Regency. The selection of the research area was carried out in purposive method. Determination of the research sample using the snowball sampling method. Collecting data using interview method using questionnaires to obtain primary data and documentation method to obtain secondary data. The data analysis method used descriptive qualitative analysis and quantitative analysis using a triangulation technique approach that tested the validity of the data using methods, sources, and theories. The results showed that the factors that significantly influenced the income of fish farmers in Nagari Andaleh, Luak District, Lima Puluh Kota Regency were the number of harvests (X1), land area (X2), production costs (X5), and the selling price of production (X6).  While the factors that do not affect the income of rice farmers are farmer education (X3), farmer age (X4) and other occupations (X7).
