Abstract

This study aims to analyze the tilapia population parameters in the waters of Lake Tempe, including estimating population parameters, as well as catches per recruit. Data on body length measurements (Lt, cm) of tilapia caught by monofilament gill net and bottom trap in October – December 2021 amounted to 1600 individuals. The tilapia growth model follows the von Bertalanffy growth model. Pauly's empirical formula and the catch curve are used to estimate the M and total mortality (Z), respectively. The fishing mortality rate (F) is obtained by F=Z-M. The value “E” is obtained from E=F/Z; (Y/R)' values using the Beverton and Hold’s formulas. FISAT-II software was used to calculate all parameters of Oreochromis niloticus population dynamics. The research results show that the estimated values for growth parameters (L∞, K, and t0) of tilapia are 35.5 cm; 0.35 per year; and -0.4512 years. The estimated of natural mortality, total mortality, fishing mortality, and exploitasi rate are 0.89 year-1 each; 2.68 years-1, 1.79 years; and 0.7. Mean while, the estimated actual Y/R' and optimal Y/R' values are 0.013 g/recruitment and 0.0155 g/recruitment, respectively. In conclusion, the tilapia in Lake Tempe takes a long time to reach its maximum length. Greater mortality is caused by arrest factors. The status of the tilapia fishery is over-exploited, in conditions where the optimal Y/R' value is higher than the actual Y/R'.

Abstract

Carcharhinus melanopterus in the southern waters of the Makassar Strait is caught with bottom longlines and bottom gill nets as bycatch, caught throughout the year without any management arrangements. The research objective was to obtain information about the size structure and sex ratio of C. melanopterus in the southern waters of the Makassar Strait. The method used is a survey method. Sample measurements were carried out at TPI Paotere Makassar City and TPI Beba Takalar Regency, South Sulawesi Province from July to September 2020. Measurement of total body length (TL:cm) and determining the sex ratio were carried out directly in the field. The results of the study on 144 sample fish showed that the total length range for C. melanopterus landed at the Paotere TPI was the same as those landed at the Beba TPI at sizes between 58 - 135 cm TL with an average length of 91.18 ± 3.32 cm TL and sizes between 51 - 139 cm TL with an average length of 91.1±2.21 cm TL for both male and female sex, respectively.The comparison of C. melanopterus landed in the two fish landing sites was in a balanced state but the male sex was smaller than the female sex.The sex ratio of male and female C. melanopterus is balanced. Most (69.44%) female C. melanopterus caught were relatively young.

Abstract

Mackerel scad (Decapterus macarellus) is a fish resource that contributes to the economic sector for fishermen in the province of East Nusa Tenggara province. Its production has increased every year. This study aims to analyze the parameters of the population dynamics of the mackerel scad. Fish samples were collected at the Oeba Fish Landing Base Kupang from April to June 2020. The data analysis used included size structure analyzed descriptively, age group using the Bhattacharya method, growth parameter values (L∞ and K) based on the von Bertalanffy equation, natural mortality using the Pauly method, and Y/R using the Beverton and Holt method. The results showed that the smallest size of the mackerel scad was 7.8 cm (FL), the largest size was 27.8 cm (FL), the average length was 19.63 cm (FL) ± 4.46, the asymptotic length (L∞) = 38.10 cm (FL), the growth parameter value (K)= 0.51 year-1, t0= -0.2996 year-1, The population consists of two to three age groups.  the total mortality value (Z)= 2.29 year-1, natural mortality (M) = 1.08 year-1, fishing mortality (F)= 1.22 year-1 and  exploitation rate (E)= 0.53 year-1. The actual Y/R value was 0.057 and the relative Y/R was 0.060 grams recruit-1

Abstract

This study aims to identify main facilities and determine the level of the main facilities utilization of Birea fish landing base, Pa'jukukang District, Bantaeng Regency. The research was conducted from May to July 2020. The method used in this research is a case study. Primary data was consisting of the length of the pier, the distance between ships, the length of time to moor, the length of the breakwater and the length of the trip, and the size and number of ships anchored, were collected through direct observation in the field. Meanwhile, secondary data such as catch production data, development of the number and types of fishing units, the size of the port pool area, and the depth of the waters were taken through the interviews method. The utilization rate of the main facilities utilization of Berea fish landing base are a pier utilization rate of 90.5%, a port pool of 72.5%, a land port 86%, and two meters of water depth are required. Based on the research results, it is found that the long pier is still possible to accommodate ships that are anchored, while the port pool and portland still meet the requirements, however, dredging is necessary for dredging the depth of the waters for shipping in and out of ships. Key words: birea fish landing base, the level of main facilities utilization, bantaeng regency.

Abstract

This study aims to analyze the level of operational performance and identify the possibility of upgrading the port class of PPI Paotere Makassar city. The research method case study is operational aspect, including facilities provision to evaluate the operational performance. The performance assessment is obtained by comparing the condition at PPI Paotere with the regulation stipulated by The Ministry of Maritime Affairs and Fisheries of Republic of Indonesia Regulation No.PER.08/MEN/2012 and also General Director of Capture Fisheries Decree No.432/DPT3/0T.220.D3/I/2008. The data are analyzed descriptively using table Sscoring method of fishery port type D operational performance. The result shows that the percentage of total production success 1.706,3%, ship visiting frequency 180%, ice service 2.466,7%, fuel service 272,55%, clean water service 52,98% and also port facilities availability such as administration office, international marketing, processing industry, marketing facilities, canteen, worship place, polyclinic and service post, but there are no fishing gear and ship repair facilities, spare parts supply and residence. The operational performance of PPI Paotere has a very good operational performance category that exceeds its capacity as a type D fishing port, but it is no longer possible to increase the port class due to the limited area.

Abstract

Makassar Strait has been identified as an area of interesting studies for marine science and operational fisheries. It provides the unique ocean structures such as topographic feature, the main path of the Indonesia Throughflow (ITF) and dynamics of thermal fronts.  The aims of this study were to map the dynamic spatial and temporal of the thermal fronts, and to describe their implications to the pelagic fisheries. We used satellite data of sea surface temperature (SST) for the period of January-December 2018 with spatial and temporal resolutions of 4 km and monthly, respectively. For fishery data, we used sampling data of skipjack tuna fishing ground distributions in October and December 2018.  Thermal fronts throughout the year were estimated using a Single Image Edge Detection (SIED) algorithm and the available fishing ground data were overlain on the SST front map.  The results showed that the spatial distributions of thermal fronts along Makassar Strait tended to be different every month. However, the thermal fronts were consistently detected near the upwelling area from June to September. Skipjack tuna fishing grounds associated with fish aggregating devices (FADs) developed in the northern area of upwelling in October. Two month later, the FADs and free swimming skipjack fishing grounds again well formed around the same location. It implies that the formation of the thermal fronts after upwelling contributes the positive effect on development of pelagic fishery especially skipjack in Makassar Strait.
