Volume hasil tangkapan dan harga ikan kembung di Kota Bandar Lampung yang terus meningkat beberapa tahun terakhir, mendorong upaya penangkapan yang semakin intensif dan ekploitatif. Penelitian ini bertujuan menganalisis hubungan panjang-berat, sebaran panjang, faktor kondisi, dan pola petumbuhan ikan kembung lelaki (Rastrelliger kanagurta) yang didaratkan di PPP Lempasing, Kota Bandar Lampung. Penelitian ini diharpakan menjadi informasi dasar bagi pengelolaan sumberdaya ikan kembung lelaki di Perairan Teluk Lampung dan sekitarnya. Sampel ikan kembung lelaki diperoleh dari ikan yang di daratkan di PPP Lempasing sepanjang bulan Juli-September 2022. Sampel ikan diukur panjang dengan pita ukur, dan beratnya mengunakan timbangan digital dengan ketelitian 1 mm dan 0,1 gr, selanjutnya dianalisis sebaran panjangnya, faktor kondisi dan hubungan panjang-berat. Ukuran panjang ikan yang didaratkan di PPP Lempasing berkisar antara 170–282 mm. Ukuran ikan terkecil pada selang kelas 170–184 mm. Ukuran ikan yang paling banyak tertangkap selang kelas 230–240 mm. Faktor kondisi tertinggi bernilai 1,02 ditemukan pada selang kelas ikan terkecil. Nilai faktor kondisi menunjukkan nilai tidak berbeda nyata dengan 1. Hubungan panjang-berat menunjukkan persamaan W=0,0017L2,086 dengan nilai koefien determinasi (R²) sebear 0,811. Pola pertumbuhan ikan kembung lelaki bersifat allometrik negatif. Hal ini menggambarkan bahwa ikan kembung lelaki lelaki cenderung pipih. Penelitian lebih lanjut terkait pola reproduksi, indeks kematangan gonad, komposisi jumlah dan produktivitas hasil tangkapan, hubungannya parameter lingkungan secara periodik dan berkelanjutan sangat dibutuhkan dalam rangka upaya pengelolaan sumberdaya ikan kembung lelaki yang presisi dan berkelanjutan.

“…The quality of the aquatic environment is one factor that affects fish's growth, survival, and production (Koniyo and Juliana 2018;Asriyana et al 2021). On the other hand, biofloc technology has the opportunity to be an alternative solution to the problem of the quality of the aquatic environment in closed-system aquaculture.…”

Abstract. Halla PTHB, Lalel, H, Santoso P. 2023. Short Communication: Comparison of the water environment aspects and production of Nile tilapia (Oreochromis niloticus) between biofloc and conventional aquaculture systems in tropical dryland region. Intl J Trop Drylands 7: 12-15. The study aimed to compare the water quality of two aquaculture systems (i.e., conventional system and biofloc technology system) used to cultivate Nile tilapia (Oreochromis niloticus Linnaeus, 1758) in tropical dry land areas. This study used a survey method using seven samples for each aquaculture system. The results of the Kruskal-Wallis test showed that there was a significant difference (P<0.05) in the content of ammonia (NH3) between the two aquaculture systems, while the content of nitrate (NO3), phosphate (PO4), dissolved oxygen (DO) and pH was not significantly different (P>0.05). Although the value of ammonia (NH3) in the biofloc aquaculture system is higher than in the conventional aquaculture system, it is still below the quality standard of the aquatic environment. Conversely, the specific growth rate (SGR), relative growth rate (RGR), survival rate (SR), and production of fish between the two aquaculture systems showed significant differences (P<0.05). Where the value of SGR, RGR, and survival rate in conventional ponds is higher than that of biofloc ponds, on the contrary, the value of fish production in biofloc ponds is higher than in conventional ponds.

The striped eel catfish, Plotosus lineatus was first described by Thunberg in 1787 from the Indo-Pacific region in the East Indian Ocean. Since then, the species has been recorded in various marine and brackish habitats in Japan, southern Korea, the Ogasawara Islands, Australia, Lord Howe Island, Palau and Yap in Micronesia, East Africa to Samoa, Madagascar, Red Sea and the Persian Gulf. Occurrences of this species have also been registered in the Mediterranean Sea, a non-native location, indicating a possible biological invasion event. Despite its long history, the taxonomic status of the P. lineatus species complex remains puzzling and uncertain. Here, we analysed all the available mitochondrial cytochrome c oxidase subunit 1 sequences (NCBI and BOLD) from specimens covering the current known distribution range, in an attempt to clarify the evolutionary relationships of different lineages within this species. We deduce nine monophyletic Lineages - I–IX, of P. lineatus with Kimura-2P distances ranging from 2% to 16%, with a mean intraspecific distance of 6%. Strikingly, Lineage V is composed uniquely of Mediterranean-captured individuals, with an unknown evolutionary origin. These findings strongly suggest the need for a careful species taxonomic reassessment. Some Lineages are composed of individuals from specific geographic locations (e.g., Australia and Indonesia), while others include specimens from broader geographic areas (e.g., almost all Indo-Pacific coastline). Additionally, several deposited sequences are most likely the result of morphology-based misidentifications. Due to the biological invasive potential, as well as the use of the species as a valuable physiology model, the P. lineatus species complex requires further attention. Overall our study offers a clear framework for future comparative studies of striped eel catfish individuals captured from different ecosystems.
