Abstract

Narrow barred Spanish mackerel and wolf herring is an important commodity that has commercialized intensively to fulfill the needs of the market, both domestic and export. Research has been conducted from June-August 2020 in Malacca Strait Waters. The purpose of this study is to analyze the dynamics of population parameters such as growth rate, mortality rate, exploitation rates, and recruitment patterns of narrow barred mackerel (Scomberomorus commerson) and wolf herring (Chirocentrus dorab). The sample size of spanish mackerel was taken at random from the purse seiner and gillnet catches. Data of size obtained were used for the analysis of population dynamics parameters. Some population dynamics parameters were estimated using the program FISAT II. Von Bertalanffy growth parameters of spanish mackerel were derived L and growth rate (K),for males 772.8 mm and 0.5/year and for females 979.65 mm and 1,7/year, and wolf herring was derived L and growth rate (K), for males 871.5 mm and 0.59/year and for females 1048.95 mm and 0.65/year, respectively. Total mortality (Z) of Spanish mackerel males and females was 0.61/year and 4.07/year and wolf herring males and females were 0.36/year and 1,3/year. Fishing mortality rate of Spanish mackerel (F) for males and females was 0,13/year and 3.07/year high than the natural mortality rate (M) 0.48/year and 1/year and the wolf herring fishing mortality rate for males and females was 0.16/year and 0.78/year lower than natural mortality rate (M) 0.52/year. Exploitation rate (E) of Spanish mackerel for males and females was 0.21/year and 0.75/year and wolf herring for males and females was 0.44/ year and 0,6/year, that almost full exploitation when compared with the optimum of 0.40. The recruitment pattern of Spanish mackerel for males was (14.59%) in June and for females was (26.84%) in August and wolf herring for males was (16.02) in June and for females was (28.63%) in July.

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

Marine heatwaves (MHWs) are extreme warming events in the ocean when the temperature detected is above the 90th percentile of climatological temperature for at least five consecutive days. MHWs events can extend up to thousand kilometers and have been detected in the subsurface layer. MHWs are described by metrics (frequency, duration, and cumulative intensity). The purpose of this study was to determine the characteristics of MHWs in the subsurface layer for 27 years (1993-2019). The data used in this study is the sea water temperature data of the depth 0,4m-763m from Marine Copernicus Global Ocean Physics and Niño 3.4 indices. The method used in this study is a statistical method to calculate the average and trend of the MHWs metric. The results of this study denotes that the occurrence of MHWs at a depth of 0.4m-92m is caused by ENSO (El Niño Southern Oscillation) positive phase (El Niño) with a delay of 7-8 months and at a depth of 109m-763m caused by negative phase ENSO (La Niña) with a delay of 1-3 months. It was also found that the frequency of MHWs was higher at a depth of 418m-763m with a maximum value is 2,6 events/year, the duration of MHWs was greater at a depth of 0,4m-77 m, with a maximum value of duration is 30-32 days/year, and the maximum cumulative intensity of MHWs events for 27 years is 90˚C. During the 1993-2019, the trend of frequency, duration, and cumulative intensity of MHWs in the subsurface layer of south Java Sea has significantly increased.

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

Abstract

Food waste in urban areas is an endless problem, considering that waste will continue to exist. The technique of managing waste to become an alternative feed for catfish is one of the steps to overcome the problem of waste and at the same time becomes an alternative fish feed solution for fish cultivators. The purpose of this research is to process food waste into fish feed. The method used in writing this article is literature review. Based on the results of the literature review and the author's analysis, it can be concluded that food ingredients that can be processed into catfish feed are food waste by utilizing fermentation or by mixing or formulated with other raw materials such as (fish meal, magot, tofu dregs, and fine bran). The fermentation process can use fishery products sold in the market, including (EM4, Boster, etc) which are mixed with molasses
