Abstract

Pearl mussels are included in commodities that almost all parts of the body can be utilized. Starting from the pearls produced, pearl clam shells, and pearl clam meat have a selling value in the market. In addition, pearl mussels (Pinctada margaritifera) have a delicious taste and have a high enough protein content to become a target for public consumption. The cultivation of this type of pearl mussel is still very little, and the utilization of this type of pearl mussel still relies on nature, this certainly has the potential for a decrease in its population in nature. This study aims to determine the effect of density on the growth rate and survival of pearl mussel juveniles (Pinctada margaritifera). This study used treatment A (8 individuals/basket), treatment B (12 individuals/basket), treatment C (16 individuals/basket), treatment D (20 individuals/basket). The results of the analysis conducted showed no significant difference (P> 0.05) in the growth and survival of pearl mussels (Pinctada margaritifera). The research was conducted for 2 months in the waters of Tanah Merah Village, Kupang Regency. Keywords: Density, Pearl mussels (Pinctada margaritifera), Absolute Growth, Survival

Abstract

In an effort to carry out cultivation activities, the obstacle is the availability of seeds is not met, so it is necessary to bring in seeds from other areas. To support cultivation activities, an effective transportation method is needed, one of which is dry system transportation or without water media. By carrying out dry transportation, it can save costs, reduce fish stress, and increase the number of transportation. This study was conducted using a completely randomized design (CRD) with 3 treatments and 3 replications, with the test organism being 5-6 cm white snapper seeds. The treatments tested were different densities, namely treatment A density of 10 fish, treatment B density of 15 fish, and treatment C density of 20 fish. Fish transportation was carried out with previous fish anesthesia, using commercial clove oil anesthetic with a dose of 0.10 ml / liter of seawater. Based on observations of transportation for 1 hour of travel, treatment C was the best treatment, namely with an inductive time of 4 minutes, a duration of unconsciousness of 1 hour, and a sedative time of 18 minutes, resulting in a post-transportation survival rate of 78% and a final maintenance survival rate of 76%. The use of clove oil is effective in maintaining the survival rate after dry transportation and after the end of the research on white snapper (Lates calcarifer) seeds.

Abstract

Saltwater ornamental fish have various species, many of which have been exported to various countries. One type of ornamental fish that can be kept in an aquarium is the clown fish (Amphiprion percula). However, clownfish tend to experience color fading when cultivated. This is caused by less than optimal food and lighting factors. The aim of this research is to determine the role of adding sweet potato flour (Ipomoea batatas) and ulva lactuca flour in feed to maintain the color of clownfish so that it remains as in nature and to support the growth of clownfish (Amphiprion percula). This research was carried out using four treatments and repeated three times, namely (1) F999 brand commercial feed, (2) 25% Ulva lactuca flour + 75% commercial feed, (3) 12.5% ​​Ulva lactuca flour + 12% sweet potato flour .5% + 75% commercial feed, (4) 25% sweet potato flour + 75% commercial feed. The parameters observed include color measurementsRed Green Blue (RGB) which is then converted to a color modelHue Saturation Brightness (HSB) and also growth. The research results show that fish color analysis usesHue Saturation Brightness (HSB), changes in hue values ​​tend towards yellow-orange colors. This shows similarities in maintaining color qualities found in clownfish in nature. However, there was no effect between different treatment on clown fish growth. The optimal dosage to achieve the desired fish color is to use 25% Ulva flour. Keywords: Amphiprion percula, sweet potato, ulva lactuca, color

Abstract

Caulerpa sp., a macroalgae from the Chlorophyceae class, represents a significant marine biological resource. In order to meet increasing market demands, sea grape cultivation has expanded through various methods, aiming to ensure production is not reliant on natural conditions. This study explores alternative cultivation by using container boxes and nutrient manipulation via fertilization to enhance the growth and production of Caulerpa sp. Specifically, the research examines the impact of different Bali Organiculture Guano liquid organic fertilizer dosages on Caulerpa sp. growth, identifying the optimal dosage for maximum growth. A completely randomized design with four treatments (A: control, B: 0.22 ml/l, C: 0.28 ml/l, D: 0.34 ml/l) and three replications were employed. Growth metrics were analyzed using ANOVA and post-hoc tests (BNT). Results indicated significant effects of fertilizer application on daily growth (A=1±0.00a, B=1±0.33b, C=2±0.00c, D=2±0.00d), absolute growth (A=38±0.88a, B=72±2.31b, C=85±2.65c, D=104±2.52d), Caulerpa length (A=1.2±0.03a, B=2.4±0.32b, C=3.0±0.07c, D=3.5±0.09c), and number of ramuli (A=22.4±0.21a, B=35.0±1.26b, C=43.0±4.31b, D=65.3±4.13c). The findings confirm that Bali Organiculture Guano liquid organic fertilizer significantly enhances the growth rate, absolute weight, length, and ramuli number of Caulerpa sp. in cultivation media.
