“…In addition to its high cruising ability, it is also capable of predating various types of prey, so it has the potential to be used as a pest control agent with a high personality. The research results of [50] indicated two types of predators with high potential to suppress B. tabaci populations in the field were Coccinella sp. and Paederus fuscipes because every 24 hours, they are able to predate up to 41 B. tabaci nymphs while the predation ability of imago is around 10-17 individuals.…”

Cylas formicarius is a major pest of sweet potato in various countries, with yield losses reaching 100%. Control technology using chemical pesticides is not successful. This study aims to examine the efficacy of the entomopathogenic fungus Beauveria bassiana compared to chemical pesticides against C. formicarius, which was conducted in Lumajang Regency, East Java, from May to September 2021. The results showed that the highest tuber productivity occurred in innovative technology, reaching 43 t/ha with only 1% tuber damage. While the productivity of the existing technology is only 20 t/ha with a tuber damage rate of 21%. The advantages of innovative technology can also be seen in the abundance of both predatory an parasitoid insects. The application of B. bassiana to control the tuber borer at the base of the stem is safer for the survival of useful insects, especially predators, and parasitoids. In addition, the tubers obtained are more organic, so the selling price of these commodities is more expensive than conventional ones. The entomopathogenic fungus B. bassiana has a great opportunity to be used as a potential biopesticide candidate to be developed as a technological innovation to replace the efficacy of chemical pesticides.

“…The other gears that caught a significant proportion of these families by weight were troll line (98.7%), dropline (93.4%), set gillnet (53.7%), and trap (100%). Although epinephelids and lutjanids were landed using boat liftnets, these data were omitted from further analysis, as this fishing method is primarily used to target anchovies and other bait fish [55,56].…”

Small-scale tropical fisheries are complex systems that utilize multiple fishing gears to target various species. In this study, we investigated small-scale reef and demersal fisheries in Saleh Bay, Indonesia, using catch and effort data from 2016 to 2019, where 57.7 percent of the catch was grouper (serranids) and snapper (lutjanids). Despite the complexity (75 documented species and eight fishing methods), this fishery is characterized by the catches of four dominant species: leopard coral grouper (Plectropomus leopardus), orange-spotted-grouper (Epinephelus coioides), spotted coral grouper (P. maculatus), and malabar blood snapper (Lutjanus malabaricus). The species caught varied among fishing methods. Over 90% of the catch was attributed to three primary fishing methods: bottom longline, speargun, and handline. Multivariate analyses found that fishing depth, season, and/or year significantly influenced the catch composition for each of these fishing methods. Fishing activities exhibit a temporal pattern influenced by monsoonal seasons. Results also suggest that fishers employ specialized fishing tactics by targeting high-value species to maximize their profits. This study recommends a management strategy of focusing on monitoring and managing the three main fishing gears and four important species during their peak seasons to reduce some of the complexity and management costs.

“…Many studies on artisanal fisheries in Java have been carried out, and Selaroides (Wijayanto et al 2019a, Wijayanto et al 2019b) is one of the catch targets for medium-sized nets such as the use of Danish seine fishing gear, which is considered an environmentally friendly fishing gear compared to trawling (Adhawati et al 2017a, Adhawati et al 2017b). This artisanal fishery has driven the economy and even continues today.…”

“…For example, capture fisheries in Pekalongan with mini purse seine fishing gear that get catches belonging to the Caranginae group, such as the type of Decapterus sp (Maulana et al 2017). In addition, artisanal fisheries in the northern waters of Java are also highly developed, such as in Banten (Barlian et al 2020;Barlian et al 2021), Tegal (Wijayanto et al 2019a), Lamongan (Syamsuddin et al 2020), and Madura (Yonvitner et al 2021).…”

Abstract. Andriyono S, Alam MJ, Sumartiwi L, Mubarak AS, Pramono H, Suciyono, Kartika GRA, Sari AHW, Sektiana SP. 2022. The diversity of Carangidae (Carangiformes) was revealed by DNA barcoding collected from the traditional fish markets in Java and Bali, Indonesia. Biodiversitas 23: 2799-2806. Biodiversity has been utilized in various ways, including in fulfilling the protein needs of fish for coastal communities. For the island of Java, with the largest population in Indonesia, the intensive fisheries in the Java Sea are sufficient to support domestic food needs. This Carangid fish diversity study in Java is the beginning to identify commercial fish in Indonesia, which have been exploited for a long time. In this study, identification was carried out molecularly in the Cytochrome c oxidase subunit I (COI) gene region with the universal primary set and found a great variety of Carangids fish species. Thirty-three fish specimens have been identified, indicating two suborder groups, Caranginae (31) and Scomberoidenae (2). The Caranginae suborder group is more dominated with the most types of which are Megalaspis cordyla (3), Atule mate (3), and Decapterus macarellus (4). Meanwhile, the Scomberoidinae suborder is Scomberoides commersonnianus and Scomberoides tala. This study also found two species that have the potential to be ciguatera poisoning agents that need to be watched out for (Decapterus macarellus and Selar crumenophthalmus). Food safety in the fisheries sector has received considerable attention for a long time. Fishery commodities in highly polluted habitats are among the chains in increasing heavy metals concentration and the other residual chemical compounds that may impact human health.
