Abstract

Sea cucumbers are phytoplankton and zooplankton (natural food) eating organisms. Availability or concentration of feed plays an important role in the growth and survival of larvae. Three types of plankton used in this study are diatom species, namely Nanocloropsys sp, Isochrysis sp and pavlopa sp which have high nutritional content and are commonly cultivated. This research was conducted to find the right and optimal type of feed in increasing the production of survival rate and growth rate of larvae of sea cucumbers (Holothuria scabra) so that the cultivation of sea cucumbers can succeed. This research was conducted in the village of Teluk Santong, Plampang District, Sumbawa Regency. The experimental design used in this study was a Completely Randomized Design (CRD) with 3 replications and 4 treatments placed at random. The results showed that the highest growth rate and survival rate of sea cucumber larvae was obtained from the treatment of Isochrysis sp. The value of the growth rate of sea cucumber larvae was 62.7 µm and the survival value was 93.33%, while the lowest growth and survival rate was in the control treatment with a growth rate value of 49.4 µm and a survival rate of 9.33%,

Abstract

The COVID-19 pandemic is a problem faced by almost all countries in the world including Indonesia which has implications for the fisheries sector. Fisheries sector players including vulnerable groups affected by COVID-19. This study aim is to analyze the application of health regulation that contain understanding and application of health regulations on fisheries and the impact of COVID-19 on commodity prices and fishing activities. The method used in this study is an online survey through a questionnaire using Google forms and in-depth interviews through the telephone network involving 45 respondents of fishermen. The survey results show that 93% of fishermen knew enough about the COVID-19 pandemic, 84% were quite worried, 7% were very worried and 9% had no effect. Most fishermen have implemented health protocol efforts including activities to wear masks, avoid shaking hands and washing hands with soap. Pandemic has an impact on the decline in fishery commodity prices by 10%. The impact of the pandemic on fishing activities is the delays in the delivery of commodity products, the decrease in the number of fishing, the decrease in the number of catches and demand for catches and the decrease in fishermen's income.

Abstract

This study aims to analyze the water parameters that support fresh fish cultivation in the Batu Bulan dam, Maman Village, Moyo Hulu District. The study used a survey method at three observation locations, inlet, center, and outlet of the dam on water quality, including temperature, brightness, substrate, pH, dissolved oxygen (DO), turbidity, salinity, ammonia, Phosphate, and depth. The results showed that the inlet temperature ranges from 29,32oC, in the middle ranges from 29,91oC, and the outlet is 29.11oC. The average brightness at the inlet is 41.04 cm, the middle is 48.20 cm, and the outlet is 34.16 cm. The substrate at the inlet and in the middle is muddy while the outlet is sandy. The pH average in inlet is 6,33, in the middle is 6,58, and outlet 6,53.  Dissolved oxygen (DO) in the inlet range is 5.34 mg/l, in the middle is 5.51 mg/l, and in an outlet, it is 5.85 mg/l. Turbidity in the inlet range is 2,44 NTU, in the middle 2,67 NTU, and an outlet is 3,26 NTU. Salinity in all locations is 0 ppt. Ammonia in the inlet range is 1,01 mg/l, in the middle 0,69 mg/l and outlet is 1,1 mg/l. The average Phosphate at the inlet is one mg/l, in the middle and outlet is 0 mg/l. The status of the water eligibility for aquaculture is that the inlet and middle of the dam are suitable for cultivation, while those at the outlet are less feasible.
