Octopus fishing activity have been established in Ampana Waters and surrounding areas since the 1990s. The goal of this research is to examine the octopus fishery in Ampana waters and its surroundings. The research methodology used in this study are CPUE and Length-based assessment which includes some analysis of catch per unit effort, fishing season, size structure, weigh distribution, length-weight relationship, fishing ground, fishing gear operation and specification, and the marketing flow. CPUE ranges from 7–15 kg/units/day, with an average of 11 kg/units/day; the fishing season runs from August to November; mantle length ranges from 8–22 cmML, and the length mode is 14 cmML; male octopus length ranges from 9–19 cmML, while the female ranges from 8–22 cmML; weight ranges from 300–2500 gr, with the male dominant at 800 gr and the female dominant at 1000 gr. Growth patterns for both males and females are negative allometric. Ampana fishermen fished around Tanjung Api, while Pagimana fishermen fished north of Bunta beach. Fishing equipment used included an octopus fishing rod, hook, and arrow, as well as aggregating devices such as gara-gara and a crustacean-like octopus fishing rod. The fishermen sold their catch to the first collector, who then delivered it to octopus middlemen in Ampana, Pagimana, and Luwuk before transporting it to Makassar.

Despite recent advances in field research on white sharks (Carcharodon carcharias) in several regions around the world, opportunistic capture and sighting records remain the primary source of information on this species in the northwest Atlantic Ocean (NWA). Previous studies using limited datasets have suggested a precipitous decline in the abundance of white sharks from this region, but considerable uncertainty in these studies warrants additional investigation. This study builds upon previously published data combined with recent unpublished records and presents a synthesis of 649 confirmed white shark records from the NWA compiled over a 210-year period (1800-2010), resulting in the largest white shark dataset yet compiled from this region. These comprehensive records were used to update our understanding of their seasonal distribution, relative abundance trends, habitat use, and fisheries interactions. All life stages were present in continental shelf waters year-round, but median latitude of white shark occurrence varied seasonally. White sharks primarily occurred between Massachusetts and New Jersey during summer and off Florida during winter, with broad distribution along the coast during spring and fall. The majority of fishing gear interactions occurred with rod and reel, longline, and gillnet gears. Historic abundance trends from multiple sources support a significant decline in white shark abundance in the 1970s and 1980s, but there have been apparent increases in abundance since the 1990s when a variety of conservation measures were implemented. Though the white shark's inherent vulnerability to exploitation warrants continued protections, our results suggest a more optimistic outlook for the recovery of this iconic predator in the Atlantic.

Nineteen broken and complete bone fish hooks and six grooved stones recovered from the Epipaleolithic site of Jordan River Dureijat in the Hula Valley of Israel represent the largest collection of fishing technology from the Epipaleolithic and Paleolithic periods. Although Jordan River Dureijat was occupied throughout the Epipaleolithic (~20–10 kya the fish hooks appear only at the later stage of this period (15,000–12,000 cal BP). This paper presents a multidimensional study of the hooks, grooved stones, site context, and the fish assemblage from macro and micro perspectives following technological, use wear, residue and zooarchaeological approaches. The study of the fish hooks reveals significant variability in hook size, shape and feature type and provides the first evidence that several landmark innovations in fishing technology were already in use at this early date. These include inner and outer barbs, a variety of line attachment techniques including knobs, grooves and adhesives and some of the earliest evidence for artificial lures. Wear on the grooved stones is consistent with their use as sinkers while plant fibers recovered from the grooves of one hook shank and one stone suggest the use of fishing line. This together with associations between the grooved stones and hooks in the same archaeological layers, suggests the emergence of a sophisticated line and hook technology. The complexity of this technology is highlighted by the multiple steps required to manufacture each component and combine them into an integrated system. The appearance of such technology in the Levantine Epipaleolithic record reflects a deep knowledge of fish behavior and ecology. This coincides with significant larger-scale patterns in subsistence evolution, namely broad spectrum foraging, which is an important first signal of the beginning of the transition to agriculture in this region.

Urine-based biomarkers are a rational and promising approach for the detection of bladder cancer due to the proximity of urine to the location of the tumor site and the non-invasive nature of its sampling. A well-known and highly investigated biomarker for bladder cancer is survivin. For detection of very small amounts of urinary survivin protein a highly sensitive assay was developed. The assay is based on the immuno-PCR technology, more precisely a solid-phase proximity ligation assay (spPLA). The limit of detection for the survivin spPLA was 1.45 pg/mL, resulting in an improvement of the limit of detection by a factor of approximately 23 compared to the previously in-house developed survivin ELISA. A key step in development was the initial isolation of survivin by a molecular fishing rod based on magnetic beads. Interfering matrix compounds pose a special challenge for further analytical application, but can be overcome by this isolation step. The assay is designed to work with only 500 μL of voided urine. The survivin spPLA showed a sensitivity of 30% and specificity of 89% for bladder cancer detection in this study of 110 bladder cancer cases and 133 clinical controls. Moreover, the results demonstrated again that survivin is a useful complementary marker in combination with UBC ® Rapid by increasing the overall sensitivity to 70% with a specificity of 86%. Although the performance for detection of bladder cancer was rather low, the herein developed assay might serve as a new tool for survivin biomarker research in diverse human fluids, even if the biological matrix is complex or survivin is only present in small amounts.

The objective of the study was to determine the diversity of fish species found in the Teunom River, Aceh Jaya Regency, Aceh Province. The research was conducted from August 2019 until Juli 2020. This research used an Exploration Method. The research station was determined by purposive sampling based on environmental conditions along river flow. Fish samples were collected using fishing rods, traps, and nets. The results of identification indicate there were 431 individual fish that were divided into 11 families and 16 species. Fish species were commonly found from the family of Cyprinidae with six species namely Labtobarbus hosii, Anematichthys apogon, Rasbora sp., Tor tambroides, Osteochilus kappenii , dan Osteochilus vittatus . The five stations’ diversity index (H’) was classified as low to moderate criterion with a value range of 0,80 to 1,86. The dominance index (C) ranged from 0,17 to 0,52. The evenness index (E) ranged from 0,43 to 0,97. While the similarity index of fish species between stations ranged from 0,0% to 0,89%. The physics-chemical condition of Teunom River water was considered to be optimum for the survival of fish.

Java Island has about 132 freshwater fish species compared to the other major islands in the Sundaland region, such as Sumatra, which has about 589 species. This study aims to reveal and identify the diversity of freshwater fish around Pulosari Village, Pangalengan District. Exploration activities were conducted in river and lake habitats of Pangalengan District, Bandung Regency, West Java. Specimens were collected by authors and local fishermen using three fishing gears: gill nets, fishing rods, and fish scrappers. Immediately after collecting, fish were documented using a digital camera to obtain their original color. In this study, a total of 11 freshwater fish species belonging to 10 families were found. Some species are recognized as introduced fish.

Abstract Fish is consumed as a rich and cheaper source of white meat and proteins all over the world. Fish farming is the leading source of income generation throughout the world. The present research study was conducted with aims to investigate the ecto and endo parasitic fauna of S. plagiostomus (snow trout) in River Swat. A total of 96 fish samples were collected on monthly basis from July-2018 to February-2019, from upper, middle and lower reaches. Fish samples were collected with the help of cast net, hand net and fishing rods. Local fishermen and experts help were also sought out for fish collection. 61 out of 96 fishes were found infected by helminth parasites. The total prevalence and intensity of 63.54% and 2.90 was observed respectively during data analysis. Highest monthly prevalence of 83.33% was recorded during July and August, while lowest prevalence of 33.33% was noted during February. Five species of helminths parasites were detected from S. plagiostomus, of which two were trematodes (Rhabdochona shizothoracis and Rhabdochona species), one species of Monogenia (Diplozoon paraddoxum), one species of Cestodes (Nippotaenia species), and one species of Acanthocephalan (Neoechynorhynchus devdevi). Highest parasite wise prevalence, intensity and relative density of 21.87%, 4.09 and 0.895 was noted for R. schizothoracis while the lowest prevalence, intensity and relative density of 4.16%, 1.25 and 0.052 was noted for N. devdevi. Highest infection of 76.08% was observed in adults host while lowest, 40% infestation rate was observed in young fish samples. 73.68% prevalence was observed in female hosts while only 56.90% prevalence was observed in male individuals. Higher infection (83.33%) was noticed during summer season, while lowest infection (44.44%) was observed during winter season. Similarly 71.79% fishes were found infected that were collected from lower reaches of the River Swat than the fish samples collected from upper reaches (52%). Resumo O peixe é consumido mundialmente por ser uma fonte rica e barata de carne branca e proteínas. A piscicultura é a principal fonte de geração de renda em todo o mundo. O presente estudo foi conduzido com o objetivo de investigar a fauna ecto e endoparasitária de S. plagiostomus (truta da neve) no rio Swat. Foram coletadas mensalmente 96 amostras de peixes, no período de julho de 2018 a fevereiro de 2019, nos trechos alto, médio e baixo com auxílio de redes de arrasto, redes de mão e varas de pesca. Pescadores locais e especialistas também ajudaram na coleta de peixes. Dos 96 peixes encontrados, 61 estavam infectados por parasitas helmintos. A prevalência de 63,54% e a intensidade total de 2,90 foram observadas durante a análise dos dados. A maior prevalência mensal de 83,33% foi registrada nos meses de julho e agosto, enquanto a menor, de 33,33%, em fevereiro. Cinco espécies de parasitas helmintos foram detectadas de S. plagiostomus, dos quais dois eram trematódeos (espécies Rhabdochona shizothoracis e Rhabdochona), uma espécie de monogenia (Diplozoon paradoxum), uma espécie de cestóideos (espécie Nippotaenia) e uma espécie de acantocéfalo (Neoechynorhynchus devdevi). As maiores prevalências de parasitas (21,87%), intensidade (4,09) e densidade relativa (0,895) foram observadas em R. schizothoracis, enquanto as menores prevalências de parasitas (4,16%), intensidade (1,25) e densidade relativa (0,052), em N. devdevi. A infecção mais alta (76,08%) foi constatada em adultos hospedeiros, ao passo que a taxa de infestação mais baixa (40%) foi encontrada em amostras de peixes jovens. A prevalência de 73,68% foi verificada em hospedeiros do sexo feminino, enquanto a de 56,90%, em indivíduos do sexo masculino. Maior infecção (83,33%) foi observada durante a temporada de verão, e a menor infecção (44,44%), durante o inverno. Da mesma forma, 71,79% dos peixes encontrados infectados foram coletados no trecho baixo do rio Swat, enquanto 52%, no trecho alto.

Rivers are highly dynamic systems. Rapid population growth and the development of industrial areas around rivers significantly influence water quality. This research aims to analyze the heavy metal content in both water and catfish in the lower reaches of the Citarum River. Five locations were purposively selected: Station 1 (26.87 m asl), Station 2 (18.35 m asl), Station 3 (22.5 m asl), Station 4 (22.5 m asl), and Station 5 (22.5 m asl). At each site, physical and chemical water parameters (temperature, pH, depth, brightness, current speed, and DO), as well as concentrations of heavy metals (Hg, Pb, and Cd), were measured. Catfish were collected using stocking nets and fishing rods from the five stations, with assistance from local fishermen. Sampling was conducted over 14 consecutive days, from June 20 to July 4, 2022. The bioaccumulation of metals in both water and catfish was analyzed and calculated using the bioaccumulation factor (BAF) formula. The results showed that the accumulation of Hg in catfish was higher than that of Pb and Cd. Spatially, Pb accumulation was highest at Station 5 (4 times that of the water concentration) and lowest at Station 2 (2 times that of the water). Cd accumulation was highest at Station 5 (5 times that of the water) and lowest at Station 2 (3 times that of the water). Hg accumulation was highest at Station 1 (6 times that of the water) and lowest at Station 4 (2 times that of the water).

ABSTRACT The largest lake on the island of Bali is Lake Batur. Fish diversity in Lake Batur is still not well understood. In order to offer correct information on the diversity of species that occur there, this research intends to update the record of fish diversity in Lake Batur. Over the lake area, observations were made at five stations throughout the dry season of 2022, which ran from August 30 to September 5th. Nine indicators of water quality were measured across all stations. In order to gather samples, fishing rods, communal 2-3-inch nets, experimental gillnets with a mesh size of 1 inch, and scoops were used. For the purpose of identifying the species, all samples were kept in 10% formalin. There were 1,104 fish samples from the lake. Abangsongan Station 4 has the most fish. The outcomes demonstrated that the water is still of acceptable quality up to the seichi disk depth. 17 species were present, which were split into 14 genera and 9 families. According to this study, Lake Batur has a remarkable diversity of fish, including climbing perch (Anabas testudineus), snakeskin gourami (Trichopodus pectoralis), and blue gourami (T. trichopterus) and beardless barbs (Cyclocheilichthys apogon), all of which were previously unknown. The Asian swamp eel (Monopterus albus) and milkfish (Chanos chanos) were not discovered, and several scientific names are inaccurate.
