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.
