Abstract

The snake-head gudgeon or payangka fish (Ophieleotris aporos), tilapia fish or mujair (Oreochromis mossambicus), and marble goby or betutu fish (Oxyeleotris marmorata) are economically important fish in Lake Tondano. However, numerous community activities can disrupt aquatic biodiversity, declining Lake Tondano environmental conditions, and other factors. This study aimed to determine the relationship between length and weight and the habitat conditions of Ophieleotris aporos, Oreochromis mossambicus, and Oxyeleotris marmorata. The method used in this study was purposive sampling with research stations located at Remboken (station 1), Kakas (station 2), and Tondano Estuary (station 3). Sampling was carried out 5 times in every 10 days. The weight and length of the fishes caught in Lake Tondano were 2-60 g and 1-8 cm (Ophieleotris aporos); 9-180 g and 6-25.5 cm (Oreochromis mossambicus); and 16-30 g and 2.6-26.5 cm (Oxyeletotris marmorata), all of them have an allometric growth pattern. Oreochromis mossambicus is the most commonly caught fish in all research stations. The research station with the best level of water fertility is Remboken Station. The habitat characteristic of Lake Tondano was 25-290C of water temperature; brightness of 1.34-2.66 m; depth of 4.23-11.8 m; pH of 6.7-7.8; and dissolved oxygen of 2.27-6.31 mg/L, which still supports the well-being of the fish.

Abstract

Regulation of the Minister of Maritime Affairs and Fisheries number 56 of 2014 and Regulation of the Minister of Maritime Affairs and Fisheries number 10 of 2015 help realize responsible fisheries management and combat Illegal, Unreported, and Unregulated (IUU) Fishing in Fisheries Management Area of ​​the Republic of Indonesia (WPP NRI). The policy of temporarily stopping permits (moratorium) for ships manufactured overseas (ex-foreign vessels) directly impacts fishermen working on ex-foreign vessels in the form of reduced income to loss of livelihoods. The research used a retrospective approach where policy analysis is carried out on the consequences of a policy after the policy is implemented. It is usually referred to as an evaluative analysis model, so it is expected to produce information that can improve the quality of the policies implemented by the government. The study aimed to determine the moratorium's impact on capture fisheries licensing on business activities, especially on fishing effort, catch per unit effort (CPUE), and socioeconomic conditions of fisheries at Benoa Harbor, Bali. This research was conducted from March to October 2022 in the Benoa Harbor Area, Bali. The data in this study were obtained from observation, interviews, questionnaires, and literature/document studies. The moratorium policy for ex-foreign vessels, followed by a ban on transshipment, significantly changed the pattern of trade, particularly for tuna, which was dominated initially by fresh tuna to frozen tuna with a lower value. The longline catches are dominated by Thunnus alalunga, followed by Thunnus maccoyii, Thunnus albacares, and Thunnus obesus. The total of ships in 2014 was 915 units, and only 246 ships remained in 2018. The significant decrease in fish landings in 2015-2017 is a real impact of the moratorium on ex-foreigners in Benoa. The results of the data analysis show that in 2014 the number of attempts was 2,264, which continued to decline until 2018, with only 697 trips.

Abstract

Sondaken Village has three mangrove zones, each with its own type of plant. The first zone, facing directly towards the sea, is dominated by Avicennia sp. The second zone, in the middle, is characterized by Rizophora sp. The third zone, closer to the land, is predominantly Bruguiera sp. Mangroves have different levels of growth, including seedling level, stake level, pole level, and tree level. The purpose of this study was to determine the types and growth levels of mangroves within its zonation in Sondaken Village, which is part of Bunaken National Park Area. This was done using exploratory and descriptive survey methods, by creating 3 plots in each zone from the edge to the center, with sizes of 10x10 m2, 5x5 m2, and 2x2 m2. The research found that mangrove in Sondaken Village consist of Avicennia sp, Rizophora sp, and Bruguiera sp, with the number of individuals per species being 124, 133, and 113 individuals respectively. Each type of mangrove has different growth levels and numbers.

Abstract

Entog Dwarf coconut is a national superior variety. The purpose of this study was to determine the vegetative growth of Entog Dwarf coconut at 7-10 months of age. The research was conducted at the Palm Plant Research Institute in Manado (Upper Kima Experimental Garden and Ecophysiology Laboratory) using a factorial group randomized design with 2 factors and 3 replications. The first factor was the planting hole with a depth of 100cm and 60cm. The second factor was compound inorganic fertilizer with doses of 1.5kg, 1.0kg, 0.5kg, and control. Nutrient analysis of soil and leaves without fertilization at 7 and 10 months and after fertilization at 10 months. The results of the analysis of variance at the 5% level showed that planting holes had a significant effect, while compound inorganic fertilizers had a significant effect on vegetative characters. The tallest plants were about 51.2-63.7cm with a dose of 0.5-1.5kg while the shortest was 27.2cm, the largest stem circumference was 10.8-11.3cm with a dose of 0,5kg and 1.5kg while the smallest was 6.42cm, and the largest number of leaves was 3.67 midribs with a dose of 1.5kg while the smallest number was 2.67 midribs, where all vegetative characters were categorized as low in control plants. The interaction between the two factors had no significant effect on vegetative growth. The vegetative characters observed were positively correlated. The results of nutrient analysis of pH, moisture content, organic carbon, nitrogen, phosphorus, potassium, stomatal index, and chlorophyll showed little difference both without fertilization and after fertilization.
