Abstract

This study aimed to determine the effect of duckweed and fish meal on feed on the growth and survival of Nirvana tilapia (Oreochromis niloticus). The tested tilapia were 8-10 cm long and weighed 12 g, kept in 9 aquariums (120 cm x 50 cm x 40 cm), three aquariums as control, three aquariums for treatment A and three aquariums for treatment B, with each each treatment A. 5% dry duckweed and fish meal (1 kg commercial feed, 25 g dry duckweed and 25 g fish meal), treatment B. 5% wet duckweed and fish meal (1 kg commercial feed, 25 g wet duckweed and 25 g g of fish meal) and treatment K (control) without treatment. The results showed that dukweed and fish meal could be used as additional feed for fish. Of the three feeds that gave the best growth, treatment A 5% (dried duckweed and fish meal) had a specific growth rate of 1.7% with a daily growth rate (GR) of 0.32 grams, and an absolute length of 3.16. cm with a survival rate of 99%.

Abstract

Betta fish, one of freshwater ornamental fish aquaculture commodities which has high sale value. Betta fish has various pattern and unique fish fin shape. Cattapa dip was a fish health product consisting of catappa leaves and vitamin C. This product could be use for betta fish cultivation so as not to be attacked by parasites, fungi, bacteria and also for helping the process of betta fish color changing. Cattapa dip could also maintain the stability of the water pH in betta fish cultivation. This product has a shape resembling a tea bag product which is very attractive and unique. This study consisted of 4 treatments and 3 replications. The treatments given were Treatment A (0.3 gram of catappa leaves and 0.1 gram vitamin C), Treatment B (0.5 gram of catappa leaves and 0.1 gram of vitamin C), Treatment C (0.7 gram of catappa leaves and 0.1 gram of vitamin C) and K treatment / control (without treatment). The parameter observed during the study was the color change of Betta fish (Betta sp) which was measured by the percentage of color change based on RGB (Red Green Blue) using the Color Picker application. The results showed that the treatment with the addition of Kataplus in the form of dip as much as 0.5 gram of ketapang leaves and 0.1 gram of vitamin C was the best treatment. Based on the results of the color changes that occur in treatments A, B, C with 3 color indicators namely Green (green), Red (red), and Blue (blue). Color changes occurred in weeks 1st to week 4th where the best were obtained in treatment B with the average percentage produced, namely Red of 125,975%, Green of 111,375% and Blue of 116,6%. So it could be conclude that the use of Cattapa dip has an effect on color changes in Betta fish (Betta sp).

Abstract

Vannamei shrimp (Litopenaeus vannamei) are one of the mainstays of Indonesia's aquaculture sector, which has great export potential. The development of Millennium Shrimp Farming (MSF) or millennial generation of shrimp farming means that the younger generation is encouraged to actively farm shrimp in a millennial way with the concept of cultivation using small amounts of land, low salinity and maximizing the regulation of water quality. Water quality in vannamei shrimp cultivation is managed by utilizing the application of probiotics and plankton growth. Plankton plays an important role in aquaculture, as natural food and an indicator of the fertility and stability of water bodies. Plankton itself is one of the main components in the food chain system and food web in vannamei shrimp cultivation. The aim of this research was to determine the type of plankton found in the vannamei shrimp ponds of Pangandaran Marine and Fisheries Polytechnic Teaching Factory. The data analysis method used is descriptive quantitative. The test parameters in this research were: plankton abundance, plankton diversity, plankton uniformity and dominance of plankton species found in vannamei shrimp ponds. The results of plankton identification in vannamei shrimp cultivation ponds in Pangandaran Maritime and Fisheries Polytechnic Teaching Factory revealed 7 species of plankton, including: (50-71)% from the Chlorophyta (green algae) group; (16-32)% from the Cyanophyta group (blue-green algae); (2-13)% from the Chrysophyta group (diatoms); 1% from the Phyrrophyta group (dinoflagellates); (2-3)% from the group of protozoa; (1-2)% from the Branchiopoda group and (2-8)% from the Euglenophyta group. The observation results show that the water in vannamei shrimp ponds has moderate biota community stability with plankton uniformity index values ​​under moderate or unstable conditions. Otherwise, there is no individual dominance in the shrimp pond waters.
