Blue swimming crab fishery in Salemo Island, Spermonde Archipelago, indicates overfishing. To ensure the sustainability of the blue swimming crab fishery, conservation effort through fishing prohibition needs to enforce. This research aimed to design a reservation area to protect the blue swimming crab resources. The study was conducted from May to July 2015. Creating a reserved area requires information on female berried crabs and larval abundance as the basic assumption that places containing the two information are the spawning ground. Information on female berried crabs in Salemo Island is readily available in the literature, while information on larval abundance must be obtained through this study before designing the reservation. Larvae of the blue swimming crabs were sampled using larval nets. Sampling was performed in three habitats: seagrass beds, coral reefs, and mangroves (estuaries). Differences between habitat’s larval abundance were analyzed using a Student T-test, while the reservation area was designed using Marxan Software. Total larvae captured during samplings were 236 individuals. Larvae were abundant in seagrass beds and coral reefs, making the two habitats suitable for the reserved area. The “no-take zone” area obtained from the analysis protects the biological parameters, less conflict with human activities, and provides minimum cost, which is fulfilled by Scenario 3.

Tujuan penelitian adalah mengidentifikasi keramahan alat tangkap jaring insang terhadap aktifitas penangkapan ikan payangka di Danau Bolano Sau melalui kajian sex ratio dan ukuran pertama kali matang gonad. Penelitian dilakukan di perairan Danau Bolano Sau pada bulan Agustus sampai Desember 2019. Sampel ikan payangka diperoleh dari hasil tangkapan nelayan yang menggunakan jaring insang dengan mesh size 3½ inchi. Analisis sampel dilakukan di Laboratorium Kualitas Air, Sekolah Tinggi Perikanan dan Kelautan, Palu. Perbedaan sex ratio ikan payangka menggunakan uji Chi-square sedangkan ukuran pertama kali matang gonad diduga berdasarkan metode Spearman–Karber. Ikan payangka yang tertangkap dengan jaring insang di Danau Bolano Sau berukuran 79-163 mm. Sex ratio antara jantan dan betina tidak seimbang dimana jantan lebih dominan daripada betina. Ukuran pertama kali matang gonad sebesar 119, 19 mm. Sehingga disarankan ukuran layak tangkap ikan payangka > 120 mm. Penggunaan jaring insang dalam aktifitas penangkapan ikan payangka berpengaruh terhadap keseimbangan populasi jantan dan betina namun sangat selektif terhadap ukuran.

The problem in the management of blue swimming crab (BSC) fisheries is a decrease in stock that overlaps with an increase in fishing activities. This study aimed to analyze the ratio of spawning potential (SPR), reproductive potential, and reproductive productivity of BSCs taken from the Spermonde Islands. Spawning potential was analyzed using SPR, while reproductive potential analysis used the relative proportion of data between female, berried female and the average fecundity of each class size. The results showed that the BSC in Spermonde were growth overfishing and recruitment overfishing. The SPR of the BSC was estimated to be 7%, below the biological reference point. The highest reproductive potential index of berried females occurred in the group with a carapace width of 111-120 mm which contributed 36.84% of the total egg production. The value of reproductive productivity was 1.35 indicating a productive population. Current legislation allows the capture of BSCs with carapace sizes larger than 100 mm. Based on the data of this study, this size limit has the potential to eliminate 65.92% of the total egg production in the Spermonde Islands. To ensure the sustainability of BSCs in the Spermonde Islands, it is necessary to limit size by capturing BSCs >120 mm to protect the berried female and increase total egg production.

Currently, spiny lobster fishery in Indonesia ranks third as an export commodity from the crustacean subphylum after shrimp and blue swimming crab – mud crab. Most of the spiny lobster export needs still rely on wild population resulting in fishing pressure. To ensure the sustainability of spiny lobster stocks, information of the Spawning Potential Ratio (SPR) is needed. This study aims to analyze SPR of spiny lobsters of Panulirus femoristriga and P. versicolor species. The research was conducted in May − November 2022 in Donggala Regency waters. SPR analysis uses the Length-Based SPR method. The results showed that the stock status of P. femoristriga and P. versicolor had experienced growth overfishing and recruitment overfishing with estimated SPRs of 17 and 11%, respectively. Fishing regulations are needed to maintain a sustainable spiny lobster fishery through increased participation of stakeholders in the implementation, monitoring and evaluation of the regulations set by the government. In addition, it is necessary to reduce of efforts 27 − 33% from the current exploitation rate to E50 0.28.

The grey-eel catfish is a highly valued fish species in some parts of Indonesia. The fish is common in brackish water of estuaries, marine and freshwater habitat. They are not are not usually catched in commercial scale because of the limited population in its habitat. Although the status is not evaluated, the fish is predicted facing extinction in several countries. We conducted a study to examine the biological information and reproductive biology of the fish in Kota Langsa to gather information that can be utilize to evaluate reproductive status of the fish in several habitats. Parameters tested in the study includes sex ratio, length-weight relationships, candition factor, size at first maturity fecundity and reproductive potential of the fish. Research results provide information that the fish follows negative allometric model with constant condition factor throughout the study. The catches were relatively young fish which have not reached maturity stage. Fishes in the class sized at 510-550 mm provide the largest contribution to total eggs production. To ensure sustainability of the fish it is advised that the fish must catched at size larger than 550 mm.

The Banggai cardinalfish (Pterapogon kauderni Koumans, 1933) is a conservation priority species in Indonesia. To date there has been no effort to rear Banggai cardinalfish on a commercial scale, so that fish are still mainly captured from the wild. Therefore, efforts are being made to develop ex-situ Banggai cardinalfish culture using different types of natural feed. This research aimed to determine the best type of natural feed to promote the growth and survival of juvenile Banggai cardinalfish. The research was conducted during December 2021-January 2022, at the Central Sulawesi Provincial Marine Affairs and Fisheries Service Hatchery, in Mamboro Village, Palu City. The study used 3 treatments with 6 replicates each: A (Artemia), B (Cullex), and C (Tubifex). The use of different natural feeds had a significant effect on net weight gain but did not have a significant effect on daily growth rate and net growth in length. Treatment B (Cullex) gave the highest net weight gain and daily growth rate of 0.08 ± 0.3 g and 0.25 ± 0.1 % respectively; treatment A (Artemia) gave the highest net growth in length of 0.5 ± 0.2; and survival rate was highest (100%) under treatment B (Cullex).

Highlight Research There are 26 species identified to be originated from the bay, which the highest diversity in Indonesia Six species found in Kwandang Bay is showing trends of decreasing populations and two species vulnerable based on IUCN conservation list Growth model and Fulton condition factor determined for 14 species indicates that they live in a good state of well beings in the bay The models and condition factors also reflect the adequate food resources required for grouper growth which makes Kwandang Bay as a good habitat for groupers Abstract Grouper fishery has been the source of income for 3,700 fishermen in Kwandang Bay. Since 2017, grouper populations in Kwandang have been depleting due to the absence of management. This research aimed to analyze species composition, length-weight relationship, and condition factor of the groupers. Samples were collected from fishers who caught the fish using traps, speargun, and handline. Samples were identified through a method by Heemstra and Randall, while the length-weight relationship was estimated using log-linear regression and t-test. The number of specimens identified during January - December 2021 was 1,571 individuals. Research showed that those samples consisted of 26 species under eight genera. Six species found in Kwandang Bay were showing trends of decreasing populations and two species were vulnerable based on the IUCN conservation list. Length-weight relationship analysis of 14 grouper species resulted in b value ranging from 1.6359 to 3.4417 and R2 ranges from 0.7718 to 0.9858. A significant test at a 95% confident interval showed that 14 species had an isometric growth pattern. Fulton condition factors show that Kwandang Bay is an essential habitat for groupers, and the bay can support the fish growth due to the adequate food availability.
