Abstract

Kappaphycus alvarezii seaweed is important for the processing industry because it contains carrageenan used as a stabilizer, thickener, material forming an emulsifier. This study aimed to find the best and optimal initial seed weight treatment for maximum biomass production, growth rate, and carrageenan content. The research location was in the waters of Aeng Batu-Batu Village, Takalar Regency, South Sulawesi in August-September 2022. The randomized block design method (RAK) consisted of 4 treatments each with 4 repetitions. Seaweed seedlings from spores were weight of 20 g, 40 g, 60 g, and 80 g planted at 60 cm depth respectively and maintained for 45 days. Data analysis used (ANOVA) and W-Tuckey to determine the differences between treatments. The result of the analysis of variences showed that the weight of 40 g, 60 g, and 80 g had an effect on the biomass production, growth rate, and K. alvarezii carrageenan content. However, the highest yield was obtained at a weight of 20 g which had a very significant effect (p<0.01).

Abstract

The purpose of this study was to determine the optimum level of addition of chitosan and probiotics in feed to increase the growth rate and daily feed consumption of giant gouramy  (Osphronemus gouramy). The method used in this research is an experimental method of completely randomized design (CRD), which consists of five treatments and three replications. The treatments used were (A) without giving chitosan and probiotics (control), (B) giving chitosan at 7.5 g/kg feed and probiotics at 10 ml/kg feed, (C) giving chitosan at 7.5 g /kg feed and probiotics at 15 ml/kg feed, (D) chitosan at 7.5 g/kg feed and probiotics at 20 ml/kg feed, (E) chitosan at 7.5 g/kg feed and probiotics of 25 ml/kg feed. The parameters measured were absolute length absolute weight, specific growth rate, feed utilization efficiency ratio (EPP), survival rate, and water quality. Data were analyzed using the Anova test at the 5% level. The results showed that the addition of different concentrations of chitosan and probiotics to commercial feeds could affect growth, and EPP but did not affect the survival rate of giant gouramy. The results obtained during the study showed that treatment C with the addition of chitosan of 7.5 g/kg of feed and probiotics of 15 ml/kg of feed resulted in the highest absolute length growth of 4.87 cm, the highest absolute weight growth of 19,35 g, the highest daily growth rate was 46,08%, the feed efficiency was 91,5% and survival rate was 97,78%. Whereas in terms of the effectiveness of treatment B with the addition of chitosan 7.5 g/kg of feed and less probiotics, namely as much as 10 ml/kg of feed, the treatment was as good as treatment C.

Abstract

The Pamarayan Dam is located in Cikeusal District, Serang Regency, Banten Province where many freshwater fish cultivators based on floating net cages are found. Important aspects that are assessed in aquaculture activities are measuring water quality, location suitability, and productivity. This study aimed to determine the site suitability criteria and analyze the existing performance of fish farming activities with floating net cages. The research was conducted from January to March 2023 at the Pamarayan Old Dam at 4 stations. Water sampling was carried out in situ and ex situ including temperature, pH, DO, TDS, current, brightness and depth, BOD, COD, total P, total N, TSS, and ammonia. Water quality analysis was carried out at the DLH laboratory in Serang City and UPT LABKES in Serang Regency. Additional data by conducting interviews with cultivators. The results showed that the Pamarayan Dam had suitability in the S2 class (appropriate) at all stations. This is based on water quality, most of which are still in accordance with class 3 quality standards including parameters of temperature, pH, BOD, TSS, DO, COD, total P, and ammonia. Cultivation performance at the Pamarayan Dam has a large advantage, where the average net profit per cultivation cycle is Rp. 41.332.000.

Abstract

PPN Karangantu is one of the fish landing sites in Serang City, Banten Province. One of the most commonly landed fish species at PPN Karangantu is mackerel. Several fishing gears are used by Karangantu fishermen to catch mackerel, including single monofilament gillnets, boat lift nets, lift nets, and lines. While mackerel fishing efforts in the 2017-2021 timeframe are likely to increase, specific management measures for mackerel fishery at Karangantu PPN have not been implemented. The purpose of this study was to determine the CPUE trend for mackerel fisheries in the 2017-2021 timeframe and to identify the dominant types of fishing gear used in mackerel fishery activities. The data used in this study were obtained from the PPN Karangantu statistical report and field observations. The collected data was processed and analyzed using CPUE and descriptive analysis. The results showed that the CPUE trend for mackerel from 2017 to 2021 tends to increase sustainably, with the single monofilament gillnet being the dominant fishing gear used in mackerel fishing.

Abstract

Lampung is one of national marine tourism destination. Seagrass is one of fragile coastal ecosystem and it is a habitat and feeding ground for a number of Echinoderms species.  Echinodermata are nutrient recyclers that will in turn provide benefits to the seagrass ecosystem. This research aimed to assess the community structure of Echinoderms and seagrass as well as the relationship between Echinoderms abundance, seagrass densities, and water quality in Mahitam Island and Ketapang Beach. Observations were conducted at 7 stations, namely 3 stations on Ketapang Beach and 4 stations on Mahitam Island. Observations included the type and number of echinoderms, as well as the type, number of individuals, and number of seagrasses stands. Habitat quality that was observed were included water quality such as temperature, salinity, pH, DO (dissolved oxygen), current speed, brightness, and TOM (total organic matter) and also observed substrate type at each station. The result elucidated nine species of echinoderms and 4 species of seagrasses were found in both study sites. The average value of Echinoderms diversity index in Mahitam Island and Ketapang Beach was low. The uniformity index of Echinoderms in Mahitam Island was medium and Ketapang Beach was low. The dominance index of Echinoderms on Mahitam Island was categorized as low and Ketapang Beach was considered high. There was a domination of an Echinoderms species in some stations. The association between Echinoderms abundance, seagrass density and habitat quality in both locations showed a positive relationship and was influenced by the habitat quality parameters of seagrasses.
