The tidal lake ecosystem is formed by the flow of the Belmera River and seawater through a tidal process along a course of 12 km from Belawan (Malacca Strait). This lake has a tidal lake that has the characteristics of fresh water to brackish water and Mollusc communities from freshwater species to brackish water species. This study was performed to develop a mollusc conservation strategy based on the spatial and temporal distribution of Mollusca in the tides. The study was conducted from September 2018-August 2019. Mollusc samples were taken every month at high tide and low tide using a Petersen grab tool. Nine Mollusca species, consisting of three bivalves and six gastropods, were identified. Polymedosa expansa is a mollusc species that is considered for conservation. The population size of P. expansa is small, and its distribution is limited to the northern lake. P. expansa was found only in September at high tide and in December at low tide. Competition among Mollusca and habitat availability are obstacles to the survival of P. expansa. The habitat of P. expansa is mangrove, and therefore a conservation approach was carried out through improvement of mangrove quality.

There are several option management measures in preventing sustainability stock of the blue swimming crab (Portunus pelagicus), i.e., nursery ground conservation. Thus, the objective of this study was to analyses habitat characteristic and its population biology in the PGN marine embayment of Labuhan Maringgai, as one among crab habitat essential in East Lampung coastal water. The potential nursery ground conservation was assessed by habitat suitability index, carrying capacity, distribution and abundance as well as crabs size. The result shows that environmental condition was still suitable, even though the habitat carrying capacity tend to degraded by an increasing of turbidity and sedimentation at the embayment mouth. The crabs captured were also not representing of peak abundance season and recruitment during sampling period, while those crab size almost 100% under Lm50. The strategic management directive is required to control in utilization of crab’s essential habitat, including crab fishing by any fishing gear resulted undersize captured crabs. Meanwhile, to propose habitat essential conservation might need more consideration and comprehensive study, including social economic and cultural aspects and co-management approach may be required in management measure applied.

Seagrass has long been known to be very sensitive to environmental changes, especially caused by human activities (anthropogenic disturbance) and has been used as a bioindicator for environmental condition. This research aimed to study interaction of Thalassia hemprichii measured and derived variables (metrics), at two locations i.e., inhabited island (high anthropogenic location) and uninhabited island (low anthropogenic location). Confirmative approach was conducted using a developed conceptual model based on preliminary studies, the conceptual model was analyzed in multivariate context using data from field observation. The result showed that Thalassia hemprichii dominated and have higher above ground biomass value in inhabited area which indicated high nutrient input, meanwhile uninhabited area showed a higher below ground biomass value. Above ground of Thalassia hemprichii that have direct effect on its biomass and below ground metrics was leaf width, meanwhile leaf length of Thalassia hemprichii have indirect effect on its biomass and below ground metrics. The result also indicated some different metric covariations which were influenced by the degree of Thalassia hemprichii density. Leaf length, leaf width, density, and percent cover of Thalassia hemprichii potentially could be used as components in multimetric index and bioindicator for environmental quality. Keywords: anthropogenic disturbance, path analysis, structural equation modeling, Thalassia hemprichii

Ikan pari totol (Neotrygon kuhlii) merupakan salah satu sumberdaya ikan ekonomis penting dan sebagai hasil penangkapan di Selat Sunda. Penangkapan yang intensif dapat mengakibatkan penurunan stok ikan pari totol. Penelitian ini bertujuan untuk mengetahui panjang bobot, dan karakteristik reproduksi. Karaktersitik reproduksi itu sendiri meliputi ukaran pertama kali matang gonad, tingkat kematangan gonad dan indeks kematangan gonad ikan pari totol (Neotrygon kuhlii) di perairan Selat Sunda yang didaratkan di Pelabuhan Perikanan Pantai (PPP) Labuan, Banten. Hasil penelitian menunjukkan bahwa nilai hubungan panjang bobot ikan pari totol betina. Berdasarkan hubungan panjang bobot ikan pari betina diperoleh persamaan hubungan panjang dan bobot untuk ikan pari totol betina : W = 0.0007 L2.1496.Sedangkan untuk pari totol jantan persamaan hubungan panjang bobot : W = 0.0000L2.251. Ikan pari totol jantan mempunyai faktor kondisi yang relatif lebih besar daripada ikan pari betina. Penurunan nilai faktor kondisi disebabkan bagian terbesar dari makanan yang dikonsumsi digunakan untuk perkembangan sel-sel reproduksinya). Kisaran ukuran pertama kali matang gonad ikan pari totol betina dengan kisaran panajng total tubuh 700-771, sedangkan untuk ikan pari jantan dengan kisaran panjang total tubuh 690-771. Tingkat kematangan gonad terbanyak betina dan jantan (TKG III) pada bulan Juni dan Juli 2013. Indeks kematangan gonad (IKG) ikan pari semakin meningkat seiring dengan meningkatnya TKG.

Ikan peperek (Leiognathus equulus) merupakan salah satu ikan demersal yang memiliki nilai ekonomis penting dan merupakan salah satu tangkapan dominan di perairan Selat Sunda yang didaratkan di Pelabuhan Perikanan Pantai (PPP) Labuan, Banten. Ikan peperek ditangkap dengan beberapa alat tangkap, yaitu payang, dogol, pukat pantai, purse seine, jaring rampus, bagan tancap, dan bagan rakit. Tujuan penelitian ini ialah mengkaji dinamika populasi ikan peperek (Leiognathus equulus) di perairan Selat Sunda. Penelitian ini dilaksanakan pada bulan April hingga Agustus 2015 di PPP Labuan, Banten. Data yang diambil pada penelitian ini berupa data biologi seperti pengukuran panjang total dan tinggi ikan, bobot basah, dan jenis kelamin. Total ikan yang diambil selama penelitan ini mencapai 1895 ekor. Hasil menunjukkan bahwa nilai koefisien pertumbuhan (K) ikan betina dan jantan berturut-turut 0.47 per tahun-1 dan 0.79 per tahun-1 dengan panjang asimptotik (Lâˆž) sebesar 258 mm untuk betina dan 210 mm untuk jantan. Nilai panjang pertama kali tertangkap (Lc) ikan peperek betina (147.57 mm) maupun jantan (142.92 mm) lebih besar dibandingkan dengan nilai pertama kali matang gonad (Lm), yaitu untuk betina dan jantan berturut-turut 116.54 mm dan 146.162 mm. Tingkat eksploitasi mencapai tingkat optimal antara 0.53-0.74. Laju eksploitasi ikan peperek telah melebihi laju eksploitasi optimum, sehingga diduga ikan peperek di perairan Selat Sunda telah tangkap lebih.

Sea ranching merupakan pelepasan ikan ke laut untuk ditangkap setelah mencapai ukuran konsumsi. Sea ranching biasanya diterapkan ketika rekrutmen alami rendah atau bahkan tidak ada dikarenakan sangat intensifnya penangkapan atau rusaknya habitat yang mendukung hal tersebut. Penelitian ini mengkaji daya dukung berdasarkan produktivitas primer. Selain itu juga mengkaji model restocking dalam sistem sea ranching.Â Kajian ini menemukan bahwa perairan Semak Daun sudah mengalami tangkap lebih rekrutmen (recruitment overfishing).Â Untuk itu perlu dilakukan restocking dengan sistem sea ranching. Daya dukung perairan bagi ikan kerapu macan, yaitu antara 0,703-1,06 ton/th dengan rata-rata 0,88 ton/th. Tebar sebaiknya diterapkan setiap bulan dan penangkapan pun dilakukan setiap hari sepanjang bulan. Pola tebar yang optimal adalah panjang benih 11 cm denganÂ padat tebar 14.000 ekor pada mortalitas tangkapan 0,5 atau panjang benih 13 cm dengan padat tebar 13000 pada mortalitas tangkapan 0,4.Kata kunci: daya dukung, Epinephelus fuscoguttatus,restocking, sea ranching
