Abstract

Shrimp cultivation has always been a star in the world of Indonesian aquaculture and today it is still one of the national priority aquaculture commodities. The market needs of domestic and foreign shrimp cultivation can be met by the high economic value of shrimp. There are many models of cultivation designs and shrimp farming systems that have been developed and used by farmers ranging from traditional to modern. The development of cultivation technology by utilizing marginal land by using plastic as a container for cultivation maintenance is called "Busmetik" technology, relatively small container sizes between 600m2 - 1000m2 are used in order to encourage young entrepreneurs or those who are new to aquaculture. Shrimp cultivation requires large funds both in investment and operational costs in its activities so that young entrepreneurs become pessimistic in starting a shrimp farming business. The banking sector can be convinced by young entrepreneurs with Busmetik technology because it can provide mutually beneficial solutions between entrepreneurs and banks. There are several things behind this Busmetik technology, namely shrimp which is currently the main focus in the cultivation business, has a stable market, the quality of the environment continues to decline, it is difficult to manage ponds with an area of >2000m2, the types of soil used for pond plots to support the Director General of Aquaculture in the shrimp farming program.

Abstract

Age and weight were the main target on domesticated shrimp due to affect on their reproductive performances. The objective of the present study was to know the effect of broodstock ages on reproductive performances of P. indicus. Two series experiments were conducted in the Hatchery Unit of MCBA Jepara by using the 1st generation (G-1) domesticated broodstocks at two differences ages such as 11 months (U-11) and 14 months (U-14). All maturation and spawning process were carried out under separated room-indoor system. Larva rearing and seed productions were conducted into 10 m-3 concrete tanks based on shrimp seed production protocols being developed on MCBA Jepara. Results found that the difference of broodstock ages significantly (p<0.05) affects on daily spawning rate, nauplii productions, spawning frequencies, and larvae survival, were (18.78±4,6 vs 8.85±3,69); (47.000±2.400 vs 27.421±8.555 N spawner-) ; (1.67 for 9 days vs 1.79 for 22 days) and (26.81±7,30% v 37.27s ± 1.95%), respectively. From the experiments it can be concluded that 11 months ages brooders were suggested for mass seed production purposed. However, further research of less than ages mentioned needs to take into account.

Abstract

Waworada Bay is a water in Bima Regency which has long been used by some people for seaweed cultivation. Currently, seaweed farmers do not know the exact harvest period. This causes differences in the harvest period between farmers. So far, research on the harvest period in Waworada Bay is not yet available. The experiments aimed to assess the ideal period for harvest among the different growth periods (35, 45, and 55 days). This research was conducted in Waworada Bay, Langgudu District, Bima Regency, West Nusa Tenggara from November 2021 to January 2022. Observation variables were absolute growth, growth rate, wet and dry biomass, productivity and water quality (temperature, dissolved oxygen, salinity, pH, brightness, current). The seaweed cultivation method uses the longline method. The results showed that the highest absolute growth was found in the 55-day harvest period (115.70±1.71 g) and the lowest was in the 35-day harvest period (55.10±6.62 g). There was a significant difference in absolute growth between treatments. The growth rate was not significantly different between treatments with a value range of 1.09±0.24 to 3.55±1.39%day-1. Wet biomass ranged from 10,022±397.22 g 12m-1 (harvest period 55 days) to (6.306±149.92 g 12m-1) (harvest period 35 days). Dry biomass ranged from 670±34.12 g 12m-1 to 1.016±53.78 g 12m-1. Productivity ranges from 0.04 to 0.07 g dry weight m−2 days−1. The average water quality values are temperature 32.40 0C, dissolved oxygen 5.84 mg l-1, salinity 32 ppt, pH 7.30, brightness 2.50 m and current 14 cm sec-1.

Abstract

Aquaponics is a combination of aquaculture technology with hydroponic technology in one system to create a symbiotic relationship between the two. The main component in the aquaponics system is fish, where fish waste and feed residues as a nutrient supply are very dependent on aquatic plants. Stocking density is one of the things that needs to be considered in aquaponic fish farming systems. Inappropriate increase in stocking density can cause adverse effects that are detrimental to farmers. This study aims to determine the best growth and density level of tilapia reared in aquaponics system. The research was carried out for 40 days in April-June 2022 at the Fisheries Laboratory, Faculty of Marine Affairs and Fisheries, Udayana University, Bali. The research design used was a completely randomized design (CRD) with 3 (three) treatments and each treatment consisted of 3 replications. The stocking density used was treatment I with a stocking density of 100 fish, treatment II 150 fish, treatment III 200 fish. The results of the study concluded that different fish stocking densities had an effect on survival, weight growth and specific growth rates. The highest survival rate was found in treatment III with an average of 87.3%, the highest weight growth was found in treatment I with an average of 3.29 grams, and the highest specific growth rate was found in treatment I of 4.67%.
