Abstract

Comet fish (Carassius auratus) is a type of freshwater ornamental fish with a high selling value due to its unique body shape and bright colour. The purpose of this study was to evaluate the effect of different LED (Light Emitting Diode) light colours on colour brightness, growth, and survival of comet fish. This study applies an experimental approach with an experimental design in the form of a completely randomized design (CRD) and consists of 5 light treatments and 3 replications, namely A (room light), B (white LED), C (blue LED), D (green LED), and E (red LED). The results showed that LED light treatment had a significant effect on the colour quality and feed efficiency, but did not significantly affect the growth and survival of comet fish. The best colour quality was found in treatment E (red LED) with an increase in the TCF (Toca Color Finder) score of 6.22 and colour performance on the back by 80.80%, pectoral fin colour by 64.91%, and tail fin by 71 .18%. The best feed efficiency was obtained in treatment C (blue LED) with a feed efficiency value of 57.48%. The behavioural responses of comet fish did not make any difference between each LED treatment. The water quality of the comet fish rearing media has a temperature value ranging from 25.70 – 29.20 C. The pH value ranges from 7.29 to 8.50. Meanwhile, dissolved oxygen ranges from 8.00 – 12.20 mg/L.

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 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 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.

Abstract

Gouramy (Osphronemus gouramy) is a freshwater fishery commodity with a large enough demand and a fairly expensive price compared to other freshwater fish. The purpose of this study was to determine the effect of temperature on larval quality and growth of gouramy fry. The research method used is an experimental method using a Completely Randomized Design (CRD) consisting of two treatments of water media temperature, namely 1) Treatment A = The temperature of the media follows room temperature (control treatment), and 2) Treatment B = The temperature of the medium was set constant at a temperature of 30ᵒC. Each treatment was repeated six times to obtain 12 experimental units. Research parameter data were analyzed statistically using variance (ANOVA) at a 95% confidence level using the t-test. The results showed that the degree of hatching of gouramy eggs, larval size, absolute growth, relative growth, daily specific growth rate and survival rate of gouramy larvae at room temperature and 30°C were 90.38% and 98, respectively. 76%; 0.54 cm and 0.66 cm; 0.86 cm and 0.87 cm; 157.52% and 133.26%; 3.99% and 3.58%; and 74.78% and 91.22%. The study concluded that eggs incubated at room temperature (25-28°C) and 30°C gave significantly different effects on hatching rates and post-hatching larvae size. Larval rearing at room temperature and 30°C gave no significant effect on absolute growth but significantly different on relative growth, daily specific growth rate and survival rate

Abstract

Lombok waters are a potential commodity area for fishing. One of the potential commodities caught is the octopus species from the octopodidae family. A recent study revised the generic taxonomy of the Octopodidae family, and several groups of species previously included in Octopus are now recognized as independent genera. However, knowledge of the phylogenetic relationships among taxa in the Octopodidae family is still lacking. This study aims to identify octopuses belonging to the genus Octopus in Lombok Waters, namely: Sari Gong Beach, Ketapang Beach, Beraringan Beach, Cemara Lembar Beach molecularly. The study was conducted from January to June 2024. Octopus samples caught by fishermen were analyzed morphologically and molecularly. The study will be conducted for 6 months from January to June 2024 in Lombok Waters. Octopus sampling was carried out once a month, observations representing the conditions of the dry season and rainy season with an interval of 30 days. The research methods used include: octopus sampling, identification, molecular identification, alignment of 16S rRNA gene nucleotide sequences, genetic distance. It is hoped that this study will be useful for providing basic information on octopus species belonging to the genus Octopus found in Lombok Waters. This information can be used for further studies on octopus biology, octopus resource potential, and studies on octopus resource management strategies in Lombok Waters. The octopus species caught in Lombok Waters were identified morphologically and molecularly as Octopus cyanea. In addition, the nucleotide base sequence can be used to design specific COI gene primers for O. cyanea

Abstract

The cultivation of pearl oysters Pinctada maxima is an important economic sector in Indonesia, but its productivity is often hampered by low growth rates and spat survival. This community service program aims to educate pearl oyster farmers in Sugian Village, East Lombok, Indonesia, through training on spat immersion techniques in natural feed tanks to improve growth. The implementation method includes theoretical and practical training for two days (August 24-25, 2024) with a community-based participatory approach, involving 20 members of active pearl oyster farming groups operating in the waters around Sugian Village. This program is supported by PT. Mutiara Surya Indonesia, a national pearl oyster cultivation company operating in Sugian village. The training materials cover pearl oyster biology, spat nutrition principles, natural feed culture techniques, immersion methods, and growth monitoring. Evaluation results show that all participants expressed that this technology is greatly needed by the community to increase cultivation productivity. The main challenges identified are the need for initial capital and access to microalgae cultures. As a follow-up, it is recommended to provide training on household-scale microalgae natural feed culture that applies simple technology, easy to understand and apply by pearl oyster farming communities. This program has the potential to increase productivity and income of local farmers. Moreover, the technology presented has prospects to be developed and replicated in other regions of Indonesia.

Abstract

Seaweed developed through tissue culture techniques has several advantages, such as high carrageenan content, rapid growth, and resistance to disease. In seaweed cultivation, growth is influenced by photosynthetic pigments such as chlorophyll. Chlorophyll plays an important role in converting sunlight into chemical energy needed for growth. This study aims to analyze the chlorophyll content in Kappaphycus alvarezii cultivated at different depths in Gerupuk Bay waters. This study used an experimental method with a completely randomized design (CRD) consisting of 4 treatments and 3 replications, namely depths of 0 cm (P1), 5 cm (P2), 10 cm (P3), and 15 cm (P4). Results of this study indicate that planting at different depths can increase the absolute weight of K. alvarezii tissue culture ranging from 283 g to 356 g, specific growth rate between 5.72%/day to 5.91%/day, seaweed production ranging from 661 g/m2 to 832 g/m2, chlorophyll content between 5.60 mg/L to 21.89 mg/L, and phycoerythrin content between 0.027 mg/L to 0.19 mg/L. The conclusion is that the cultivation of K. alvarezii tissue culture with floating rafts at different depths can affect growth and yield. Cultivation of K. alvarezii seaweed at a depth of 0 cm using the floating raft method gave the best results, namely increasing absolute weight up to 356 g, specific growth rate up to 5.91%/day, and production up to 832 g/m2, supported by chlorophyll content of 21.89 mg/L and phycoerythrin content of 0.195 mg/L. For optimal production results, it is recommended to use a depth of 0 cm in floating raft seaweed cultivation.

Abstract

Kappaphycus alvarezii is a red seaweed commonly found in the Indo-Pacific region. Seaweed plays an important role in daily life due to its high nutritional value and its content of hydrocolloid compounds such as carrageenan, agar, and alginate. Carrageenan is categorized into three types: iota, kappa, and lambda. It is widely applied in various sectors including food, pharmaceuticals, and cosmetics. This study aimed to identify the optimal cultivation depth to maximize the carrageenan content in Kappaphycus alvarezii. The research employed an experimental method using different depth treatments over a cultivation period of 45 days. A completely randomized design (CRD) was applied, consisting of four treatments with three replications, resulting in a total of 12 experimental units. The treatments were as follows: P1 (0 cm depth), P2 (25 cm), P3 (50 cm), and P4 (75 cm). The research procedure included the construction of floating rafts, seedling preparation, tying of seedlings, planting, sampling, and harvesting. The best results were observed in treatment P1 (0 cm depth), which yielded the highest carrageenan content at 40%, the greatest absolute weight at 350 grams, and the highest specific growth rate at 5.90% per day.
