Status Assessment

PPI Kedonganan is a fish landing base located in Kedonganan Village, Kuta District, Badung Regency. One of the fish commodities that landed at PPI Kedonganan is Lemuru Fish (Sardinella lemuru). The high rate of catching Lemuru must be balanced with proper management so that Lemuru Fish Resources remain sustainable. This study was conducted to determine the status of the utilization of Lemuru fish resources. The study was conducted from January 2021 to March 2021. Data collection was carried out by observation and interviews. Data analysis of each indicator was carried out using a multi-criteria analysis approach with composite index assessment and visualization by flag model. Indicators were observed the trends of fish size, the proportion of juvenile fish were caught, the species composition, range collapse of fish resources, Endangered, Threatened, and Protected species. The status assessment of the Lemuru resource domain which landed at PPI Kedonganan is in the good category with a composite value of 66.7. Results of the trend indicators of fish size is relatively fixed, the proportion of fish juvenile caught about 90%, the composition of species caught was 100% of the target fish i.e, lemuru that caught by using gill net, range collapse of fish resources as much as 57% of fishermen expressed relatively fixed in looking for fishing grounds, and ETP species not found.

The Status

There are a large variety and quite abundant types of small pelagic fish that have high economic value in the Sulawesi Sea. One of which is the blue scad fish or commonly known as malalugis (Decapterus macarellus). This study aims to analyze and determine the status of scad fisheries management and to develop recommendations in the management of scad fisheries in the waters of Sulawesi Sea, North Sulawesi Province. The evaluation of fishery management status is carried out using multi-criteria analysis (MCA) through the development of composite index of each indicator of Ecosystem Approach to Fisheries Management (EAFM). The results showed that, in general, the status of scad fisheries management in North Sulawesi Province, was in ‘good’ category, specifically reviewed from the domain of fish resources fall into the category of “medium”, habitat and ecosystem “good”, fishing techniques “good”, economy “not good”, social “medium” and institutional “good”. Management actions take precedence over domains that have “poor” indicator values. Priority management action is implemented in the economic domain, followed by the domain of fish resources, social, institutional and fishing techniques.Indonesian title: Pengelolaan perikanan ikan layang (Decapterus spp.) di perairan Laut Sulawesi, Provinsi Sulawesi Utara, menggunakan EAFM

Given the prevalence of lateral ankle sprains during physical activity and the high rate of reinjury and chronic ankle instability, clinicians should be cognizant of the need to expand the evaluation of ankle instability beyond the acute time point. Physical assessments of the injured ankle should be similar, regardless of whether this is the initial lateral ankle sprain or the patient has experienced multiple sprains. To this point, a thorough injury history of the affected ankle provides important information during the clinical examination. The physical examination should assess the talocrural and subtalar joints, and clinicians should be aware of efficacious diagnostic tools that provide information about the status of injured structures. As patients progress into the subacute and return-to-activity phases after injury, comprehensive assessments of lateral ankle-complex instability will identify any disease and patient-oriented outcome deficits that resemble chronic ankle instability, which should be addressed with appropriate interventions to minimize the risk of developing long-term, recurrent ankle instability.

The research aims to record the types of shark utilization in Selayar Islands Regency, explore the spread and shark status of the Regency of Selayar Islands, and examine the sustainability status of shark utilization by fisherman in Selayar Islands. The research method was based on the assessment of EAFM indicator assessments to assess the performance of shark resource management on Tarupa Island, Rajuni Island, Polassi Island and Kayuadi Island Selayar Islands Regency with an indicator approach involving two domains, i.e (1) Fish resources and (2) Fishing technique. The methods of obtaining the data were survey by extracting the data through interviews/questionnaire. The sample was determined using purposive sampling technique. The results of the research indicate that the status of utilizing shark fishery in Selayar Islands Regency is currently in medium category. The main issues indicated are a decrease in catch size and the catch of sharks that are not feasible to catch (50% of catch <Lm). The domains that need to get primary attention in the management of sharks fisheries are the domains of fish resources and fishing technique. The efforts of management carried out in each fields are based on central issues that emerge. Connectivity efforts between communities and institutions are needed to produce functional fisheries management status so that the sustainability of shark resources in Selayar Islands Regency can be sustainable

Abstract.—Spiny dogfish <em>Squalus acanthias </em>have been an important component of the Strait of Georgia fisheries from the late 1800s to the late 1940s, when the fishery collapsed owing to overfishing and changes in market demand. The stock population levels have sustained a commercial fishery of approximately 2,000 metric tons since 1978. Recent concerns regarding the status of dogfish stocks worldwide have reprioritized the status assessment of dogfish in British Columbia. Longline research surveys were conducted for dogfish in the Strait of Georgia in 1986, 1989, and 2005. Additional sources of information are catch and effort data collected through logbook records from the commercial longline fishery. Recent improvements in gear configuration resulted in a switch in the mid-1990s from traditional J hooks to circle hooks, which makes direct comparison of catch rates difficult. In November 2004 a calibration experiment using J hooks and circle hooks demonstrated that, overall, spiny dogfish catch per unit effort (CPUE) for circle-hook gear was 1.6–1.7 times higher than that for J-hook gear. After applying this conversion to the commercial longline CPUE data available for 1980–1984 and 2000–2004, no significant trend in catch rate over time was detected. The catch rate observed in the longline research survey actually increased in 2005 compared to 1986 and 1989. In both fisheries and research data, the proportion of smaller spiny dogfish in the size distribution has increased, reducing the overall mean size. The decline in mean size is probably due to an increase in recruitment of juvenile fish. However, caution in management of this stock is warranted given that the current commercial fishery is now landing a large proportion (estimated 80%) of immature fish. Increased fishing pressure on juveniles could have implications for the abundance of mature fish in upcoming decades.

The Status

The article is devoted to the analysis of some specific characteristics of the language of normal science described by Thomas Kuhn. We would like to draw attention to two problems associated with some features of the concept of paradigms. The first problem relates to the question, how scientists belonging to one paradigm record the position of a group of scientists adhering to another paradigm. Precisely, the article examines how the problem of “synchronous fragmentation of knowledge” is solved in the language of science. The second issue concerns the age of “normal” knowledge and the question, how the anomalous content of knowledge can appear and accumulate, and what is the status of scientists developing the “anomalous” knowledge. We reveal some possible parameters by which we can determine the early stage of the functioning of normal science, the periods of its heyday and decline. In this article, we try to find an approach to these problems by examining the natural language of scientists, using techniques of content analysis, as well as complex linguistic analysis, including discursive, semantic and pragmatic components. Linguistic analysis can’t finally solve the problems of philosophical analysis of scientific knowledge, in particular, the state of the paradigm concept by Thomas Kuhn. But it helps us to identify the boundaries of paradigms, as well as the state of normal knowledge. The problem of fragmentation of knowledge by paradigms, as well as the problem of “aging” of knowledge inside a “normal science” are not directly expressed by scientists. But they can be recorded by analysis of everyday language, which often becomes entangled with the language of science. The high rate of words that semantically indicate the “obvious” knowledge in scientific texts points to a “good” state of the paradigm. And vice versa, the words denoting “improbable” indirectly indicate its crisis state or express an attitude to the knowledge belonging to a different paradigm. The analysis of the data shows that the alleged complete replacement of Kuhn's concept of a paradigm by the concept of “trading zones” by Peter Galison does not appear to be accomplished. Just as the concept of scientific paradigm did not completely replace the falsificationalism, the Galison’s “trading zones” do not fully reflect the real state of affairs in science. Therefore, the Kuhnian paradigms are recorded at the lexical level in the communication of scientists.

The Status

Fish biodiversity on Hau (Bassac) river was investigated to assess the status of species composition and fishing by fishing gears during a year. Sampling was implemented monthly at the upper part (An Giang province), middle part (Can Tho City) and lower part (Soc Trang province) of Hau River using trawl net as main sampling gear. Additionally, fish composition was also recorded from four other most popular fishing gears including cast net, gill net, fixed net and hook operated in the study sites. Fish species composition was determined by fishing gears and their abundance (CPUE) was calculated only from the main sampling gear (trawl net). The results showed that a total of 176 fish species belonging to 16 orders and 49 families was recorded. Perciformes was the most abundant group with 51 species followed by Cypriniformes with 46 species. The number of fish species was decreasing from upper part to lower part. Trawl net was considered the most destructive gear as up to 145 fish species caught by this device, followed by gill net with 98 species, fixed net 75, cast net 57, and hooks 16 species. CPUE was very low ranging from  0.53 kg.ha−1 h−1 to 26.30 kg.ha−1 h−1. Higher CPUE was recorded at lower part in compared to upper part and middle part, and at dry season in compared to rainy season. Regulation on fishing gears, fishing ground and season should be taken into consideration to protect and conserve the resources.
