Abstract

Belawan Harbor of North Sumatra is the third-busiest seaport in Indonesia and a gateway to the economic activity in the respective area. This study aimed to analyze the harbor water quality status and its sources of pollution. The data used for this study was the secondary data from the book of harbor environmental management and observations in 2015-2018 and the governmental regulation number 22 of 2021 on the harbor water quality standards. The observation was conducted in 14 different stations.  The data obtained was then analyzed using STORET and pollution index to determine the quality status then using Pearson correlation to correlate the data. The results showed that according to the pollution index method, the water in Belawan Harbor is categorized as in good condition (comply with the water standard). However, according to the STORET method, the harbor water quality status is in mild pollution categories. The ocean fishing harbor of Belawan (station 7) and Deli estuary (station 8) have the highest number of pollutants. Overall, the water status in the harbor of Belawan is within the threshold of the designated water standard. The polluted conditions generated from anthropogenic activity such as industrial, fishing and agriculture activity and also affected by the geographical location of the habor which located in the estuary area. In addition, the temperature, turbidity, and salinity are the main factors affecting the water ecosystem in Belawan Harbor.

Abstract

Feed is very important in the development of fish farming because around 70% of fish farming production costs come from providing feed. To support the growth and brightness of the color of koi carp, it is necessary to have nutritional content and β-carotene according to the fish's needs. Feed that meets the nutritional needs of fish can increase the growth and color brightness of koi carp. This research aims to determine the effect of feed doses containing shrimp head meal, carrot flour and red spinach flour on the growth and color brightness of koi carp.This study aims to determine the effect of feed doses containing shrimp head meal, carrot flour and red spinach flour on the growth and brightness level of koi goldfish. This research was carried out from November to December 2022 at the Tatelu Freshwater Aquaculture Fisheries Center (BPBAT). The method used was an experimental method with a completely randomized design (CRD) consisting of 4 treatments and 3 replications. Treatment A = (control giving 5% feed dose without containing shrimp head meal, carrot flour and red spinach flour) treatments B, C, and D (feeding containing shrimp head meal, carrot flour and red spinach flour dose 5%, 10 % and 15%). In order to find out the results of the influence of feeding containing shrimp head waste flour, carrot flour and red spinach flour, the data obtained includes the results of calculating the level of color brightness and growth in koi fish calculated using analysis of variance (ANOVA)Based on the results of the study, absolute length growth in treatment D with a dose of 15% had a very significant effect with a value of 1.56 cm, while for the brightness of the color in treatment C, with a dose of 10%, it had a very significant effect with an average value of 10.69, while the growth weight and survival of koi goldfish were not significantly different.

Abstract

Sandfish (Holothuria scabra) are one of the economically important marine animals found in the coastal of the Kei Islands (Tual City and Southeast Maluku Regency). The large exploitation pressure caused the sandfish population in the Kei Islands to decline drastically. This problem can be overcome by farming activities (greeding, nursery and grow-out). Nursery is an important segment in the farming series because through nursery the seeds are prepared to a size that good for rearing in grow-out containers or restocking into nature. This research aims to see the effect of giving Sargasum sp and Ulva sp extracts on the growth and survival of sandfish juveniles. This research doing from August – September 2022 at the Tual Teripang Center, Ohoitel village, Tual City. Juvenile sandfish used as research objects size 3 – 6 mm and stocking density is 40 individu per container. The feed used as treatment was Ulva sp extract 50 g/container (treatment A) and Sargasum sp extract 50 g/container (treatment B). Feeding is done every day and water changes are 70-100% per day. The calculation of growth and survival rate is the variable that observed in this study. The average absolute growth in body length in treatment A was 0.69 mm and in treatment B was 1.72 mm. Through the T test on growth, it was obtained that Pvalue (0.0006) < α (0.05) which means that the two treatments had different effects on juvenile growth. For survival, the average percentage for Treatment A was 40% and Treatment B was 62.5%. Through the T test on survival, it was obtained that Pvalue (0.0048) < α (0.05) which means that the two treatments had different effects on the survival of juvenile sea cucumbers. It was concluded that treatment B was better for the growth of juvenile sandfish than treatment A.

Abstract

Koi fish, a popular freshwater ornamental fish with high economic value, is known for its attractive shape and color. Intensive cultivation of koi (Cyprinus rubrofuscus) using sistems such as Recirculatory Aquaculture Sistem (RAS) and aquaponics presents profitable business opportunities. However, land conversion for development reduces cultivation areas and water quality, necessitating innovations to ensure the sustainability of fish farming. The RAS sistem utilizes filters to recycle water, while aquaponics uses plant media for filtration. Research conducted from February 7 to March 19, 2024, at UD. Pojok Koi Farm, Gresik, East Java, aimed to compare koi growth under these two cultivation sistems. The results indicate that neither the aquaponics sistem nor RAS significantly affected koi length and survival, but both had an impact on weight gain and feed conversion ratio (FCR). Water quality, including pH, temperature, and DO, plays a crucial role in koi growth. pH and temperature remained within suitable ranges, while DO levels met the minimal requirements for koi in both sistems. Good water quality and effective filtration sistems support the growth and health of koi fish.
