Abstract

Intensive vannamei shrimp cultivation is a high-density culture to get maximum results with the use of limited cultivation space. High cultivation activities cause high waste production, which inhibits growth, survival rate, and feeds conversion ratio (FCR). This study aims to determine the cultivation of vannamei shrimp with an intensive system on growth, survival rate, and FCR. The research was carried out in Lengokjawa, Pangandaran in the period March–May 2022. The research was carried out by means of a survey and analyzed by a quantitative descriptive approach. The results of the study obtained growth values, namely: Mean Body Weight (MBW) ranges from 1.61 to 21.11 g/head, Average Daily Growth (ADG) ranges from 0.14 to 0.62 g/day, size is 49 fish/kg and biomass is 7,680 kg. The survival rate value obtained is around 95.07 – 84.87%, while the feed conversion ratio (FCR) value ranges from 1.2 to 1.5. In general, the results of growth, survival rate, and FCR showed high performance and supported the success of vannamei shrimp culture with intensive system

Abstract

Kappaphycus alvarezii is used in industry as a food ingredient, a source of hydrocolloids, cosmetics, food additives, animal feed, fertilizers, biofuels, and medicinal ingredients. K.alvarezii is cultivated in several areas in Indonesia, including on the island of Lombok. The production of K.alvarezii is related to its growth and it is related to its phytohormones. K.alvarezii cultivated in Lombok is currently not known for its composition and amount of phytohormones. The content of phytohormones at different planting ages is of course different. The purpose of this study was to determine the number of phytohormones in seaweed K. alvarezii at different planting ages. This study was conducted in Ekas Bay, Lombok, Nusa Tenggara Barat from June to December 2020. The study used experimental methods and descriptive data analysis. The results of this study explain that currently cultivated K. alvarezii contains cytokinins, auxins, and gibberellins. Cytokinins obtained on the 9th day of planting were 11.62 ppm and increased on the 18th day to 12.34 ppm. At the next planting age, it continued to decrease on the 27th day to 11.43 ppm, and at harvest time, the 45th day of 10.69 ppm. Auxin detected in the seeds used was 644.93 ppm, on the 27th day of 14.27 ppm, and on the 36th day of 1078.25 ppm. Giberilin was detected on the 9th day at 0.49 ppm. This study concluded that K. alvarezii at different planting ages had different phytohormones content
