Abstract

The size of the gill net in the waters of Pangkalan Terap Village is 2.5 inches, 3 inches, and 5 inches, but its use is still based on the current season. This study aims to determine the effect of gillnet mesh size on catches, determine the number, type, weight, and size of catches, and determine the size of gill nets that are effectively used to catch fish in Pangkalan Terap Village. This research was conducted in April - June 2022 in Pangkalan Terap Village, Teluk Meranti District, Pelalawan Regency, Riau Province. The method used in this research is an experimental fishing method with a Randomized Group Design. The results showed that the mesh size of 2.5 inches, 3 inches, and 5 inches in the rainy and dry seasons in Pangkalan Terap Village had a significant effect on the number and weight of fish caught (Fcount> FTable). The number of fish caught in the rainy season was 219 fish weighing 46259 g, while in the dry season, 241 fish weighing 79435g. The types of catches in all nets in both seasons were ten species dominated by Cyclocheillichthys sp. 2.5-inch gill nets are more effectively used because they get the most diverse catches compared to other nets

Abstract

The size of the harbor pool will affect the number of ships that will dock. The purpose of this research is to determine the size of the port pool needs and determine the depth of the port pool needed for smooth activities at PPS Bungus. Data collection is done directly in the field to see the maximum number of ships anchored the port pool area (m2), the depth of the port pool (m), data on the width, length, and depth of the largest ship (m), the maximum tide in the port pool (m), and the squat or height of the oncoming ship (m). The results concluded that the existing harbor pool is no longer able to accommodate all ships that dock. The current harbor pool area is 40,000 m2 with 348 vessels, requiring a pool area of 458,762.06 m2. The current average harbor pool depth is 2.75 m, and it is safe for ships to anchor in the harbor pool

Abstract

Production of catches on hand line fishing gear at Kutaraja Ocean Fishing Port has declined. This is seen from the level of fish production produced, which was 2.407.580 tons in 2018, compared to in 2019 which was 2.285.750 tons. The fishing business, which has become one of the livelihoods of the Indonesian people, is a little riskier than other businesses because the fish, which are the play target of this business, are constantly moving dynamically. The research objective was to determine productivity per GT, Trip, and ABK on hand line fishing gear and to determine the financial feasibility analysis of fishing effort on hand line fishing gears at Kutaraja Ocean Fishing Ports. The benefits of this research are to increase knowledge and insight regarding productivity and financial analysis of the fishing line effort. The method used in this study is a survey method. The data analysis method used in this research is descriptive. The results showed that the value of productivity per trip with large-size ships has a high amount of production compared to smaller ship sizes. Hand line fishing with a vessel size >30 GT has a relatively long payback period, <5 years. While ships with a height of 5 GT, 6 GT, 9 GT, 22 GT, and 24 GT have a payback period of <3 years

Abstract

The Java Sea is influenced by various atmospheric and oceanographic factors such as monsoon winds and the inflow of water from adjacent seas, thus leading to the formation of thermal fronts. In this research, the atmospheric process over the thermal front was estimated by using sea surface temperature (SST) gradient and crosswind-SST gradient calculation based on the GLORYS12V1 monthly SST data from Copernicus Marine Service (CMEMS) and the ERA5 monthly surface wind data from European Centre for Medium-Range Weather Forecasts (ECMWF) for 27 years (from 1993 to 2019). Moreover, the oceanic process was determined from the volume transports of three major channels surrounding the Java Sea, which are Karimata Strait, Sunda Strait, and the eastern boundary of the Java Sea. Based on the annual variance analysis, there are four main thermal front areas, such as Northern Java Coast (NJC), Eastern Sumatra Coast (ESC), Western Borneo Coast (WBC), and Eastern Borneo Coast (EBC). The annual variation of the thermal front over the ESC, WBC, and ESC has two peaks in March and October, while the NJC thermal front area has three peaks in March, July, and November. This study results that the thermal front activities over the NJC, WBC, and EBC are significantly correlated to the wind stress curl over those areas, with a coefficient correlation of about 0.62, -0.92, and -0.73, respectively. In addition, the increase in thermal front activity over the NJC area is controlled by negative wind stress curl with no lag time, while the WBC and EBC areas are controlled by positive wind stress curl with a lag time of 1 month (wind stress leads). On the other hand, the thermal front activity over the ESC area is closely related to southward volume transport from the Karimata Strait, with a correlation coefficient of -0.74 and a lag time of 2 months (volume transport leads).

Abstract

Cd is a non-essential metal and a widespread micropollutant that has physiological effects on aquatic organisms. Cd heavy metal poisoning can be acutely caused by contamination at high doses, while chronic poisoning is generally caused by low levels of contamination and long exposure time. This research was conducted in June 2022 at the Marine Chemistry Laboratory Faculty of Fisheries and Marine, Universitas Riau, which aims to determine the value of LC50 (Lethal Concentration) for 24 hours after being given a toxicant in the form of Cd and to determine the level of Cd toxicity in A. salina. The method used in this research is the experimental method with the experimental unit A. salina. The LC50 of Cd on A. salina revealed 11.7109 mg/L. This concentration is capable of causing the death of 50% of the test animals. Furthermore, the water quality in the acute toxicity test, P0 (control), was classified as good to support the life of A. salina, while at P1 (3.13 mg/L) - P5 (50 mg/L), it was classified as polluted

Abstract

Tropical cyclones are one of the meteorological phenomena that can have negative impacts on humans. These impacts can include heavy rainfall leading to floods and even storm surges. However, tropical cyclones can also have positive effects as they can trigger upwelling. Upwelling affects the fisheries aspect because in areas where upwelling occurs, sea surface temperatures are lower, and nutrients (such as phosphate and nitrate) are lifted from deeper layers of the ocean, which can affect the growth of phytoplankton. The objective of this research is to identify and analyze the upwelling phenomenon in the waters south of Java Island during the occurrence of Tropical Cyclone Charlotte. The data used in this research includes the intensity and movement direction of Tropical Cyclone Charlotte from the zoom.earth website and sea surface temperature, chlorophyll-a, mixed layer depth (MLD), and sea level anomaly data from the E.U. Copernicus Marine Service Information (CMEMS)-Global Monitoring and Forecasting Center during March 17-28, 2022. The results of this research indicate that upwelling was not identified during the period before or after the cyclone, as evidenced by sea surface temperatures between 28.5-29.5°C, chlorophyll-α concentration of <0.15 mg/m3, and a sea level rise of 0.1 m

Abstract

Upwelling events that occur in the Halmahera Sea are influenced by the El Nino Southern Oscillation (ENSO). Upwelling can cause sea surface temperatures to be lower than normal, affecting the potential of fishery resources in the region. The purpose of this study was to determine the conditions of sea surface temperature, chlorophyll-a content, salinity, and upwelling conditions when viewed from the parameters of chlorophyll-α content and sea surface temperature when El Nino was strong, El Nino was weak, La Nina was strong, and La Nina weak and in normal conditions in the Halmahera Sea region. The data used in this study include the Oceanic Nino Index, sea surface temperature, salinity, and chlorophyll-α content during the 2010–2019 period. A quantitative descriptive research type is used by filtering ENSO data to determine when ENSO occurred, then visualizing the data in each parameter and analyzing it. The results of this study show that upwelling is known to occur in the northern to western parts of the Halmahera Sea. When the El Nino phase is vital, the upwelling parameter changes, the sea surface temperature decreases to 27.1⁰C, the chlorophyll-α content increases to 0.70 mg/m3 compared to the normal phase, and the upwelling intensity changes.

Abstract

Gill nets are placed perpendicular to the water to block the swimming direction of the fish. Fish are caught by being entangled in the meshes or entangled (spun) in the body of the net. This research was conducted in Pambang Pesisir Village, Bantan District, Bengkalis Regency, to know the composition of the catch and the selectivity of drift gill nets, comparing the composition of the number, type, weight, and size of the catch from different mesh sizes, and knowing how to catch fish (entangled, gilled, snagged, wedged) on the same mesh used. This research was carried out in December 2020 using the experimental fishing method, which is a research method that uses samples of research objects caught on fishing gear for observation. The research results of drift gill nets are species-selective fishing gear. Moreover, drift gill nets with a mesh size of 7.62 cm are more selective than nets of 5.72 cm because they have a catch ratio value closer to 1 and catch more large fish (worth catching). How to catch fish with a mesh size of 5.72 cm, many fish were caught by snagged; namely, 65 fish (30%), wedged 61 fish (28%), gilled 59 fish (27%), and 33 fish entangled (15%). Meanwhile, for the mesh size of 7.62 cm, 30 fish (31%) were caught wedged, 27 fish (29%) snagged, 27 fish (29%) gilled, and ten fish entangled (11%).
