Abstract

The fourfinger threadfin, Eleutheronema tetradactylum is one of economic demersal species in Indonesia. Information of its biology was needed to ensure the sustainable fisheries management of this species. This study aimsto estimate the lengthweight relationship and condition factor of E. tetradactylum landed in Sedati, Sidoarjo, East Java. In total, 649 samples were randomly collected from Sedati Fishing Base during the study. The results indicated that E. tetradactylum has negative allometric growth pattern (b = 2.8, p<0.05), means the growth of length was faster than weight. In addition, the average value of relative weight condition factor (kn) was 1.01, which is greater than or equal to 1, means E. tetradactylum live in good growth conditions. This finding contributes to managing E. tetradactylum fishery in the north Java waters, especially in East Java. As this study was conducted from unsexed samples, future research with focuse on sexed samples is suggested to give more comprehensive result.

Abstract

Squid (Loligo spp.) belongs to the Cephalopoda group (squid, cuttlefish, octopus) and is one of the primary export commodities in the fisheries sector. National squid production increased by 5.5%, from 193,583.82 tons in 2020 to 204,156.28 tons in 2021. However, the potential sustainable catch in the Java Sea (WPPNRI 712, including the Madura Strait) has experienced an average annual decline of 1.9% from 2017 to 2022, dropping to 66,608 tons in 2022. This study aims to identify the species composition of squid, analyze length-weight relationships, and determine the mantle length at first gonad maturity (Lm). Data were obtained from fixed lift-net catches and analyzed in the Fisheries Exploitation Laboratory of Universitas Brawijaya. The results identified two main species: Photololigo duvaucelli (Indian squid) and Sepioteuthis lessoniana (bigfin reef squid). The composition of squid catches was 1.29% in purse seine operations and 2.91% in payang (seine net) operations. The length-weight relationship of both species exhibited a negative allometric growth pattern, where length growth outpaces weight gain. The sex ratio between males and females was balanced for both species. The mantle length at first gonad maturity (Lm) was greater than the mantle length at first capture (Lc), indicating that the catch was dominated by immature squid. These findings highlight the need for minimum catch size regulations to ensure the sustainability of squid resources in the Tuban waters.

Abstract

Anggota famili Leiognathidae atau Peperek termasuk dalam kategori minor commercial, berfungsi sebagai komoditas ketahanan pangan sehingga kurang mendapat perhatian untuk diteliti. Penelitian ini bertujuan untuk membuktikan hipotesis penemuan seluruh genera dari Leiognathidae pada perairan Pantai Jawa Timur. Sampel ikan dikoleksi dari hasil tangkapan nelayan dengan alat penangkapan ikan; Jaring Tarik, Cantrang, dan Mini-Trawl dari Januari 2023 sampai Oktober 2024. Analisis genus dilakukan melalui deskripsi morfologi eksternal, morfometri, dan penyelidikan otolith. Studi otolith dilakukan melalui koleksi sagittae dari tulang telinga di belakang otak. Analisis morfometri untuk memperjelas definisi bentuk tubuh menggunakan perangkat lunak TpsDig. Total 12 variabel morfologi digunakan untuk menjelaskan masing-masing kerabat pada genus. Sementara deskripsi otolith dianalisis dengan menggunakan 15 variabel bentuk, cekungan, dan tonjolan dari otolith. Dendogram dihasilkan dari analisis morfologi dan otolith untuk memisahkan kekerabatan di antara genus. Hasil analisis membuktikan bahwa terdeskripsi total 10 genera dari famili Leiognathidae yaitu; Leiognathus, Aurigequula, Eubleekeria, Photopectoralis, Nuchequula, Karalla, Gazza, Deveximentum, Equulites, dan Photolateralis. Genus Gazza ditemukan pada seluruh lokasi sampling. Namun genus Karalla hanya ditemukan pada lokasi sampling di Selatan Barat Jawa Timur (Pantai Dangkal Pacitan, dan Prigi Trenggalek). Hasil analisis dendogram berhasil menempatkan Equulites satu kerabat dengan Photolateralis, namun tidak berhasil memisahkan antara Leiognathinae dengan Gazzinae. Sebaliknya, analisis menggunakan morfologi otolith tidak berhasil menempatkan Equulites satu kelompok dengan Photolateralis, namun bisa memisahkan antara sub famili Leiognathinae dengan Gazzinae. Kondisi lingkungan geografis mungkin menjadi faktor utama terjadinya adaptasi morfologi eksternal dan otolith yang berbeda. Deskripsi morfologi dan otolith bisa digunakan sebagai indikator apomorfi genus. Analisis genetik melalui DNA barcoding masih diperlukan untuk menelusuri kekerabatan diantara genus.   Members of family Leiognathidae are included in the minor commercial category, functioning as a food security commodity so that they have received less attention for research. The study aims to prove the hypothesis of the discovery of all genera of Leiognathidae within coastal waters of East Java. Fish samples were collected from the catches of fishermen using fishing gear; Beach Seine, modified Danish Seine, and Mini-Trawl, from January 2023 to October 2024. Genera analysis was carried out through external morphological descriptions, morphometry, and otolith investigations. Otoliths were collection of sagittae from the ear bones behind the brain. Morphometric analysis to clarify the definition of body shape were using TpsDig software. A total of 12 morphological variables were used to describe each genus within family. While the otolith description was analyzed using 15 variables of shape, depression, and protrusion of the otolith. Each dendrogram was generated from morphological and otolith analysis to separate the clade among genera. The results of the analysis proved that all 10 genera of Leiognathidae were described, consisting of: Leiognathus, Aurigequula, Eubleekeria, Photopectoralis, Nuchequula, Karalla, Gazza, Deveximentum, Equulites, and Photolateralis. The genus Gazza was found in all sampling locations. However, the genus Karalla was only described in two sampling locations in Southwest of East Java (Pantai Dangkal Pacitan, and Prigi Trenggalek). The results of dendogram analysis succeeded in placing Equulites in the same clade as Photolateralis, but failed to separate Leiognathinae from Gazzinae. On the other hand, the analysis using otolith morphology failed to place Equulites in the same group as Photolateralis, but could separate Leiognathinae from Gazzinae. Geographical barriers and environmental factors might be the main factor in the occurrence of different morphological and otolith adaptations. Genera can be distinguished through external morphology and otolith description. Genetic analysis through DNA barcoding is still needed to trace the lineage among genera of Leiognathidae.

Abstract

The southern waters of Java are suitable to be the largest supplier of Yellowfin tuna exports in Indonesia, but have not efficiently produced the expected yield. This research minimizes these constraints by modeling the yellowfin tuna fishing grounds in the southern waters of Java based on oceanographic factors such as Sea Surface Temperature (SST), chlorophyll-a (CHL_A), Sea Surface Salinity (SSS), Sea Surface Height (SSH) using an integration between remote sensing, Geographic Information Systems (GIS), and the Generalized Additive Model (GAM) statistical method. This study used oceanographic factor data from Aqua MODIS Level-3 and Copernicus, while yellowfin tuna fishery production was obtained from Palabuhanratu Nusantara Fishing Port (NFP), Cilacap Ocean Fishing Port (OFP), and Pondokdadap Coastal Fishing Port (CFP). The modeling process used 80% of the data, while the remaining 20% was used to validate the model results. The order of influence of oceanographic parameters from largest to smallest is SST > SSS > SSH > CHL-A. The best model from the GAM analysis showed that the combination of four oceanographic parameters had the greatest influence on yellowfin tuna CPUE. The catch per unit effort (CPUE) of yellowfin tuna was predicted to be high in May-October and low in November-April. The prediction model had high accuracy because most of the fishing activity was in the HSI 0.4-0.5 range and the RMSEP value was 0.63. Yellowfin tuna were suitable in habitats distributed from inshore to offshore in June and July, but less suitable in December.

Abstract

Perairan Samudra Hindia Timur memiliki keanekaragaman lobster yang tinggi, di mana Indonesia menjadi habitat bagi 6 dari 19 spesies Panulirus yang ada di dunia. Wilayah barat Pulau Sumatra, yang termasuk dalam kawasan ini, memiliki potensi besar dalam perikanan lobster. Penelitian ini bertujuan untuk mengkaji komposisi spesies, distribusi panjang karapas dan berat lobster beserta pola pertumbuhannya, serta menilai kesesuaian hasil tangkapan dengan ketentuan PERMEN KP No. 16 Tahun 2022 di perairan Sumatra Barat dan Pulau Tello, Sumatra Utara. Analisis yang digunakan meliputi identifikasi spesies, komposisi, distribusi frekuensi, chi-square, ANOVA satu arah, dan regresi. Hasil menunjukkan bahwa di perairan Sumatra Barat ditemukan enam spesies lobster, dengan Panulirus homarus (lobster pasir) sebagai spesies dominan, sedangkan di Pulau Tello ditemukan empat spesies, dengan dominasi P. versicolor (lobster bambu). Distribusi panjang karapas tertinggi di Sumatra Barat terdapat pada kisaran 8–9 cm (442 ekor), dan berat pada 220–360 gram (529 ekor), dengan pola pertumbuhan alometrik negatif. Di Pulau Tello, panjang karapas terbanyak berada pada kisaran 12–13 cm (30 ekor), dan berat pada 500–640 gram (25 ekor), juga menunjukkan pertumbuhan alometrik negatif. Seluruh komposisi lobster yang tertangkap di kedua lokasi dinilai layak tangkap berdasarkan ketentuan regulasi yang berlaku.   The East Indian Ocean holds significant potential for lobster diversity, and Indonesia is home to 6 of the 19 Panulirus species found globally. West Sumatra, located within this region, has promising lobster resources. This study aimed to assess species composition, carapace length and weight distribution, growth patterns, and compliance with fishing regulations (PERMEN-KP No. 16/2022) in the waters of West Sumatra and Tello Island, North Sumatra. Analytical methods included species identification, composition analysis, frequency distribution, chi-square testing, one-way ANOVA, and regression analysis. Findings revealed that six lobster species were identified in West Sumatra, dominated by scalloped spiny lobster (P. homarus), while four species were found on Tello Island, with painted spiny lobster (P. versicolor) being most abundant. In West Sumatra, the dominant carapace length class was 8–9 cm (442 individuals), and the most common weight class was 220–360 g (529 individuals), both exhibiting a negative allometric growth pattern. Meanwhile, Tello Island lobsters showed a dominant carapace length of 12–13 cm (30 individuals) and weight range of 500–640 g (25 individuals), also with negative allometric growth. Overall, the lobster catch composition from both locations was found to comply with the sustainable capture guidelines outlined in PERMEN-KP No. 16/2022.

Abstract

The world finfish database reports that Indonesia has more than 3,647 species of marine fish in the finfish category. Fisheries statistical data divides marine fishery catches into 92 species categories. It is very possible for one species category to be composed of more than 15 different taxonomic species. This research aims to analyze the composition of kembung-mackerel species as representatives of the small pelagic group, including the composition of catches in the Purse Seine and the peak fishing season. A total of 15 specimens in the mackerel fish category were sampled to trace morphological and genetic characters (COI region DNA analysis). Other fish were also searched for local names and morphological characters. A total of 744 Purse Seine catch data were monitored from three TPIs in Lamongan: Kranji, Labuhan, and Lohgung between February to July 2023. At the same time, monthly data compilations were also collected from January 2018 to May 2023. The results of DNA analysis found four identified species often reported as mackerel fish, are: Rastrelliger brachysoma, R. faughni, Scomber australasicus, and Sarda orientalis. These results are in accordance with the morphological characters of the keel (caudal peduncle), inter-dorsal region (between the first and second fins), finlets, and combination of ornaments in the dorsal and ventral regions. All these characteristics make it different from other members within the Scombrid family. Mackerel as a whole constitutes 37.1±24.2% of the total catch after tongkol (little-tuna). The peak mackerel fishing season starts from April to July, preceding the peak tongkol fishing season which starts from October to February the following year. Knowledge about this season is often used as a basis by fishermen to change the size of fishing gear, in adaptation to environmental conditions.

Abstract

Understanding the natural bait preference of predatory fish, such as barramundi, plays a crucial role in improving capture efficiency. This knowledge also supports sustainable fisheries by optimizing bait selection for handline fishing and reducing reef damage by active gear where barramundi species commonly live. This study examines the response of barramundi to various types of natural bait and investigates whether body size plays a significant role in this response. Predatory fish are divided into three different sizes (9, 13, and 15 cm total length), with each size having nine replicates. Fishing behavior and response to baits were divided into four phases: arousal, searching, finding, and uptake. Kinovea computer software (www.kinovea.org) was used to identify each phase with visual support from iVcam. The experiment was designed using a 54 L aquarium filled with saline water of 32 ppt. Data were analyzed using one-way ANOVA in SPSS version 26. When significant differences (p<0.05) were found, Tukey's post hoc test was performed. Bait from trash fish and shrimps did not show significant differences (p>0.05). Worms provided the fewest responses on times and behavior. Body size did not significantly affect behavioral responses or response times (p > 0.05). In conclusion, bait type significantly influenced barramundi's responses, with worms eliciting a significantly slower response compared to shrimp and trash fish, which were equally effective.

Abstract

Graphical Abstract Highlight Research The size of the first mature gonads in hulu'u fish can be analyzed. Differences in sperm and egg size characterize sexual maturity. Sexual maturity is not influenced by season. Hulu'u fish have an asynchronous spawning type. Abstrack Understanding fish reproduction biology, particularly sexual maturity, the reproductive cycle, and fecundity, is useful for managing fisheries. The reproduction of Giuris margaritaceus in Limboto Lake is regrettably unknown. Over a year, fish specimens (N = 662) were gathered. They ranged in length from 6.5 to 20.9 cm (mean SD 10.9±2.5). Fecundity varied from 30,057 to 61,920. The first sexual maturity of male and female fish occurred at different sizes, 11.2 cm and 10.3 cm, respectively. This information is needed to determine this fish's lowest acceptable harvest length under the management aim to enter all-female fish for reproduction at least once. We estimated the reproductive of G. margaritaceus cycle using the size of the oocytes, histological analysis of the ovaries, and monthly mean GSI. These techniques produced the same reliable conclusion: G. margaritaceus can spawn yearly, with maximal between September and October. Based on this finding, spawners of Giuris margaritaceus can be kept from entering the reproductive stock between September and October. Future efforts to fine-tune fishing efforts for the effective management of G. margaritaceus may be aided by the study's findings.

Abstract

Oryzias hubbsi's distribution is rarely discussed, as it is believed to only occupy the western part of Java, while its conservation status is Near Threatened (NT) as of 15 October 2018 on the IUCN red list. Specimens of O. hubbsi were recorded from Bandung and Jakarta in the description, other reports for O. hubbsi are commonly from Southern Sumatra-Western Java (SWJ) ecoregion in Java. However, an unexpected discovery of the genus Oryzias in Semarang freshwater opens up opportunities for the hidden spread of O. hubbsi to Central Java, and especially to other ecoregions which is Central and East Java (CEJ). Morphological approaches with distinctive O. hubbsi characters, complemented by molecular approaches with O. hubbsi samples from the Bogor population, confirmed similarities of species between both populations. Genetic distance using p-distances between both populations was below 2%, both populations made obvious clusters with a gap of 0.5%, and differed by five nucleotide base sites only. This new distribution record of O. hubbsi can be a foundation for conservation and domestication planning efforts.
