Abstract

Bagan Apung fishing gear is one of the fishing gear that uses light as a tool in the fishing process. Floating Bagan fishing gear is a fishing gear that produces a high enough value for fishery production. The value of marine fishery production sometimes experiences instability which can be caused by several factors including oceanographic, weather or climate factors and the period of the moon phase. The research method used in this study was observation or following the fishing operation directly on Bagan Apung as many as 16 trips. Data analysis was carried out to see the effect of the catch on the moon phase using the t test and the BNT follow-up test. The composition of the catch shows that the crescent phase has a catch composition of 33% or with a total catch of 884 kg. The first bright spring moon phase with a catch composition of 17% or with a total catch of 454 kg, the full moon phase with a composition of 13% or with a total catch of 346 kg. The second semi-bright moon phase with a composition of 37% or with a total catch of 987 kg. The results of the t test and further test (BNT) showed that there was a moon phase on the catch of Bagan Apung.

Abstract

Lobster farming still depends on larvae from nature, while the number of larvae caught is small and the size is not uniform. The effectiveness of a trap is caused by various factor. So that in this study it was tested based on the depth test of trap placement and forming material. This study aims to compare the effective trapping materials and identify the trapping depth according to the type and size of post larvae lobsters. The results showed that at the depth of trapping, namely sand lobsters at a depth of 14 meters with a total of 35 heads and a size of 5 cm, was found mostly at a depth of 14 meters with a total of 25 individuals. In the comparison of cement bag trap materials, the catch was the highest, where the cement bag type of lobster larvae that was caught the most was the sand lobster with a total of 154 and in the cement bag, size 5 was obtained with the most number caught. At a depth of 14 meters and cement sack material, the highest number of post-larval lobsters was caught, namely sand lobsters and 5 cm in size, the highest catch was obtained.

Abstract

Gear selectivity is an important part of controlling the size of fish that are suitable for catching so that fish resources are maintained. The size of the hook is one of the factors that affect the selectivity of the fishing line. The purpose of this study is to analyze the selectivity of fishing lines on the results of catching Selar crumenopthalmus. Fish sampling was carried out by following a series of fishing operations by fishermen using hook sizes no. 17 and 18. The Holt method was used to analyze and calculate the selectivity of hook size operated by fishermen on the total length of the fish line. Size distribution of the total length of hook no. 17 in the middle-class size 16.5 cm – 22.5 cm and hook no. 18 in the middle-size class 16.5 cm – 20.5 cm. The distribution of length sizes on both hooks tends to be normally distributed and the proportion of large lengths is higher on hook no. 17. The 50% and optimal (100%) chance of being caught for hook size no. 17 is 18.3 and 20.1 cm, respectively. while the size of hook no. 18 is 167 cm and 18 cm. It is recommended to use hook size for trevally resources in the Seram Strait waters is hook no. 17.

Abstract

Fishing boat has unique characteristics, such as seaworthiness, maneuvering, boat’s velocity, displacement, fishing gear layout, and catch storage facilities. With increasing development of photographic technology, photography is not merely an art but it has become a field of mathematics, making it a technique that can be integrated with software technology designed to produce digital data objects in the form of 3D images called Photogrammetric technique. This study is to obtain the reconstruction of the boat's hull based on the Photogrammetric software, to determine the effect of photography to obtain a 3D image, and to know the weakness and strength of 3D reconstruction of the boat’s hull. The images in this study were obtained using a POCO F3 smartphone camera integrated with the PIX4Dcatch application and analyzed with Agisoft Metashape Professional (Trial Version). From this research, we concluded that 1) the reconstruction of the boat hull can be obtained by using Photogrammetric techniques in the PIX4Dcatch application followed by the Agisoft Metashape Professional (Trial Ver.) software analysis; 2). With photographic equipment and several data processing software, the boat’s shape could be produced in 3D images, and 3). There are several advantages in reconstructing the ship's hull with the Photogrammetric technique, namely producing the ship's reconstruction of 3D images, obtaining the principal dimensions of the boat, such as the area and volume of the boat, that could be as the basic data for boat resistance and ship stability calculation, and the work could be done by one person only.

Abstract

It can be said that a fishing port has carried out its functions properly if all the facilities owned by the port, including the main facilities, functional facilities, and supporting facilities, are in accordance with what is expected. This research was carried out by following the descriptive method. The data taken in this study are primary data and secondary data. PPI conditions were analyzed descriptively. The steps taken to analyze the condition of the facilities are (a) taking an inventory of the types and conditions of existing facilities; (b) collect data on the size and capacity of each facility, and (c) look at the procedures for using the facility, whether it is in accordance with its function. The main facility is a facility at a fishing port that is used for mooring and berthing of fishing vessels and minimizes natural disturbances and shipping safety. The main facilities at the Amurang Fish Landing Base include the Harbor Pool Pier, Complex Roads, Mooring Poles. Functional facilities are said to be superstructures where these facilities function to increase the use value of the main facilities that can support activities at fishing ports. These facilities, among others, do not have to exist in a port, but these facilities are provided in accordance with the operational needs of the port. Functional facilities at the Amurang Fish Landing Base include Fish Auction Sites, SPDN (Solar Packed Fishermen Dealers), Cold storage, Packing Buildings Supporting facilities are facilities at fishing ports that can indirectly help and support the activities of fishing communities and even the general public Mess Office Extension Post Guard Post.

Abstract

This study aims to examine the safety and health aspects of fishermen who use compressors. This research is a descriptive study to describe the use of compressors as a diving aid and its impact on the lives of fishermen. Data collection methods were carried out through surveys and interviews, as well as using questionnaires. The process of data processing and analysis was carried out through the use of cross-tabulation and presentation in the form of pictures, diagrams, and histograms. Several things can be conveyed as a result of this study, namely: the use of compressors as a breathing aid is very dangerous to health because it does not follow the existing diving rules such as diving procedures and the use of air filtering filters that are not used, and the accumulation of negative impacts on the safety of fishermen’s lives, and there have been several fishermen who have died.

Abstract

Covid-19 brought their intensive effects in marine fishery subsector in Manado by the end of 2019. The research aimed at finding out how far the effect of purse seine fishery contribute on Gross Regional Domestic Product (GRDP) Manado between before and after Covid-19. Secondary data collected from of BPS Manado dan North Sulawesi in 2018 - 2022, while primary data i.e purse seiner’s catches and its value production from the annual reports of Tumumpa coastal fishing port by direct observation on board. Data was analyzed using Location Quotient (LQ) approach. The result of data analysis showed, there was a declining production during Covid-19 due to a lack of fishing operation activities, having a consequence in fish production value decreasing, because the fish distribution obstruction from the centres of producer to the centres of consumer. Before Covid-19 period, it gained the average catches of 10,7 million tons.yrs-1 (increasing 17,46% yrs-1), with production value of Rp. 159,6 billion yrs-1 (increase 23,23% yrs-1). During Covid-19, average cathes of purse seiner was 11,3 billion tons yrs-1 (decline 8,25% yrs-1) and production value of Rp. 204,3 billion yrs-1 in average (decline of 8,30% yrs-1). Purse seine fishery contribution on GRDP Manado decrease from 0,10% yrs-1 before Covid-19 (2017-2019) to - 0.42% yrs-1 during Covid-19 (2020-2012). During these two periods, (marine) fishery subsector had a LQ < 1, meant that this subsector was really not a basis of the subsector. To fulfill the Manado society consumption on fishes, it is required to supply fishes from other locations. The other side, the business of purse seiner fishery brought an agreeable advantage.

Abstract

Fishermen in North Buru often depend on seasonal changes in tuna madidihang abundance to plan their fishing operations. However, a more comprehensive understanding of how this seasonal variability affects catches and its implications for fisheries management is still an important research subject. The research was conducted in Wailihang Village, Waplau District, North Buru Regency, between October and December 2022. The observational method was used for this study, where available and precise time series data owned by the Indonesian Community and Fisheries Foundation (MDPI) was collected. The collected data is the number of catch productions (kg) and the total length of fish (cm) from each haul. Yellowfin tuna production tends to fluctuate, with the highest catch (CPUE) occurring in September (63.8%) and the lowest in June (34.2%). The west season and east seasons have a total catch of 556 fish (45.42%), with 382 fish (31.21%) caught during the east season and 174 fish (14.22%) caught during the west season. The distribution of fish length varies in the east season compared to the west season. The west season catches more fish, but they are generally small-sized, while during the east season, large fish dominate, with the highest presentation (38.67%).

Abstract

The aim of this research is to determine the differences between two types of artificial bait on troll line on catches and to identify the composition of catch types based on bait type. This research was carried out in Tanawangko waters and was carried out from February to March 2023 using the experimental fishing method, where two pancing tonda  each using silk fiber and chicken feather bait were operated simultaneously in one boat for 5 trips which were then analyzed using the t test. The catch during the research was 24 individuals with 3 species, namely with silk fiber bait, 20 individuals were caught consisting of 3 species and using chicken feather bait, 4 individuals were caught consisting of 2 species. The analysis results show that tcount = 1.684 < t table = 2.776; so it accepts H0 and rejects H1. This explains that the use of chicken feather bait is not significantly different from silk fiber as trolling bait for catch results. The conclusion of this research is that using silk fiber bait resulted in more catches than chicken feather bait, but the results of the t test analysis showed that the two were not significantly different and the three species of fish caught were 15 skipjack tuna (Katsuonus pelamis), 7 baby tuna (Thunnus sp.), and 2 lemadang (Coryphaena hippurus).
