Abstract

The aim of this study is to find out the composition and condition of phytoplankton in the white shrimp (L. vannamei) culture inffected by the white feces disease so that one of the indicators of the onset of the white feces disease can be known. This research uses descriptive methods. The observed parameters are the identification of species diversity, abundance, diversity index and dominance index of phytoplankton. The sampling was conducted at three locations, Tuban area, Situbondo area, Lamongan area. The results of the study showed observations in Lamongan area, the total abundance of phytoplankton was 473 cells/L. Situpondo areas abundantity of phytoplankton total was 633 cels/L and Tuban areas abundance was 887 cells/L. In Lamongan area, the diversity index was 1,009. In Situbondo areas diversity Index was 1,013. In Tuban area, diversity indexes were 1,082. In Lamongan area, a dominance index was 0.477. In Situpond area, it was obtained a domination index of 0.544. The genus that dominates the three ponds are Cyclotella and Navicula. At all three locations have high variety of species and abundance of the genus members of the filum Cyanophyta and Bacillariofhyta are detrimental, the genuses that are found are indicators of contaminated waters. The dominance of Cyanophyta (blue-green algae) is also an indicator of the White Feces Disease.

Abstract

The food industry with the fastest rate of growth in more than 50 years is the fisheries sector. The sector of aquaculture and capture has grown to be very promising. In order to support the success of this business, the aquaculture industry in freshwater and marine environments is currently progressing. In the larval stage, choosing fish feed that is of high quality is crucial. The primary food source for fish larvae to support the growth and development of farmed fish is natural feed with a high protein content. Numerous varieties of farmed fish and ornamental fish have been fed Tubifex tubifex, a natural silkworm food. Protein and fat content in this polichaeta class worms are respectively 66% and 12%. When farmed fish are growing and developing, the high protein content of these worms may serve as their primary source of protein. Several initiatives are currently being made to enhance worm protein quality by consuming more food that contains macro- and micronutrients. Agricultural waste that has fermented or decomposed, which is typically regarded as waste, has nutritional value that can be combined with mud or sand to keep worms for a while. The nurture of fish larvae or fry may one day be possible using silkworms.

Abstract

Fish farming has become essential in meeting the global demand for animal protein, with the maintenance of fish larvae being a crucial stage in determining production success. Tubifex worms, rich in essential nutrients, have long been used as natural feed in aquaculture. This article provides a comprehensive review of the utilization of Tubifex worms, covering their morphological and anatomical characteristics, habitat, and nutritional content. The benefits of using Tubifex worms as natural feed include enhanced growth and health of fish larvae and cost efficiency in production. This article also outlines feeding procedures, risk management, and challenges in the mass production of Tubifex worms. Additionally, recent research and practical approaches that can be implemented to optimize the use of Tubifex worms in fish farming are discussed, providing guidance for fish farmers and researchers in aquaculture.
