Abstract

Local people name Selaroides leptolepis distributed in Tomini Bay as Oci Fish. A study of the fish reproductive biology, which is one aspect of fisheries biology, is crucial to support the implementation of sustainable Oci Fish resource management policies. This study aims to determine the average length at first maturity, gonad maturity stages, and fecundity of the fish in Tomini Bay. Sampling was carried out using a stratified random sampling method from the catches of the fishermen landed in Fish Landing Base Kampung Tenda, Gorontalo City. The time interval sampling was conducted per month during April, May, and June 2020. Fish and egg samples preserved using ice cubes and a 10% formaldehyde solution correspondingly. The results of the study showed that the Oci Fish in Tomini Bay had a length range of the first maturity between 166 and 174 mm with a gonad maturity index ranging from 1.773 to 2.760%. The average fish fecundity was 16623 ± 4850 eggs.

Abstract

ABSTRACTSkipjack (Katsuwonus pelamis) is the one commodity that the waters of the Gulf of Tomini which potential and high economic value, and the fishermen used with various types of fishing technology. The aims of this study was to see whether the fish catches of skipjack influenced by extrinsic factors such as zones, depth, and season and knowing revenue per fishing effort. This study used primary data, especially on fish resources obtained through direct observation of research and interviews with actors fishery (fishing/crew, ship owners, collectors, officers TPI and other stakeholders), and the option to use a list of questions/questionnaire structured according to the research objectives. Secondary data were collected through the reporting of fisheries statistics include statistical data of domestic fisheries (RTP), statistics fleets and fishing gear, production data from the Department of Fisheries and Marine Gorontalo Province, Department of Fisheries and Marine Pohuwato, the Central Bureau of Statistics of Gorontalo Province Development Planning Agency Regional and Tomini Bay Sustainable Coastal Livelihoods and Management (SUSCLAM). In addition, a variety of literature supporting this research e.g. scientific publications, local publications and other documents. Data analysis was performed using resources through the stock abundance index data recording catches and the number of trips/boat/gear in the time series, to determine the allocation of fishing effort on the abundance of fish. Next will be the calculation of the catch per effort (CPUE, Catch per Unit of Effort). Analysis of the allocation of fishing effort done using monthly seasonal index (%), and forecasts an economic advantage by analysis Revenue per Unit Effort (RPUEj). The results of the study explained that the test results obtained by a factor wald gear types, depths and seasons significant effect on catches of tuna with a p-value <5%. The zone does not affect the catches of skipjack. Based on the Monthly Seasonal Index (Ij) that Ij the August high of 69, 05% then followed in July by 65, 94%. The results of the analysis Revenue per Unit Effort (RPUEj), the value of the highest RPUE for flying fish and tuna occur on in October of IDR 102,325,862.Keywords: resource analysis, skipjack, PahuwatoABSTRAKIkan cakalang (Katsuwonus pelamis) merupakan salah satu komoditas perikanan di perairan Teluk Tomini yang potensial dan bernilai ekonomi tinggi, dimanfaatkan nelayan dengan berbagai jenis teknologi penangkapan ikan.

Most of the corn commodities in Omuto Village are marketed in primary form (fresh corn) or shelled dry maize with a low selling value. This program of KKS Service activities aims to increase the added value of corn through the diversification of processed food. The target of this activity is so that the target group can acquire skills in processing various kinds of products made from corn, so that gradually they are motivated to develop businesses with a commercial-business mindset. This KKS Service activity will be carried out from September to October 2020. The technique used to socialize innovations in the field of food processing technology to the public is through communicative learning through training activities. Efforts to empower the community in Omuto Village are carried out by providing guidance and transfer of knowledge. technical skills and how to process corn commodities into processed products in the form of home industries

Abstract

This study aimed to identify the inventory of gastropod species and Density at The Mangrove Ecosystem in Pentadu Timur Village, Tomini Bay, Gorontalo, from March to April 2022. Two observation stations were determined from purposive sampling, which was carried out in five transect lines and four quadrants measuring 1x1, while the gastropod samples were taken and then placed in a plastic bag for identification and documentation. In contrast, the density analysis was carried out descriptively by differentiating each species of Gastropod. The results showed that eight families and 11 species of gastropods were identified, namely; Monodonta labio, Cassidula aurisfelis, Littoraria sulcata, Nerita planospira, Chicoreus capucinus, Cerithium kobelti, Nassarius polygonatus, Cerithidea obtusa, Telescopium telescopium, and Tereblaria palustris. In both stations within the tourist area, two types of gastropod species experienced the highest and lowest densities for two months, namely Nassarius polygonatus, found at 20.4 ind/m² in march and 18.4 ind/m² in April, whereas the protected forest areas that species Telescopium found 14.2 ind/m² in march and 12.40 ind/m² in April

Abstract

The objective of this research was to determine the species composition and abundance of fishes in the waters of Tontayuo Village and Lamu Village, Batudaa Pantai Subdistrict, Gorontalo Regency. This research was conducted from April to May 2022. The data collection of this research was carried out using a net with a length of 50 m, a widh of 2 m, and a mesh size of 1.5 cm drawn in the seagrass meadow, and it was replicated three times at each station, namely station I (Tontayuo Village) and station 2 (Lamu Village). The findings denoted that the highest species composition was found at station I with 34 species, while at station 2, there ware only 11 species. At the same time, the highest abundance value found at station 1 was Piotosus lineatus species, and the highest abudance at station II was Caranx melampyus species. Overall, the finding signified that the composition and abundance of fishes at station I and station II ware highly different due to the different water condition and fishing times.
