Substrat mangrove terdiri atas fraksi pasir (sand), lumpur (silt), dan liat (clay). Gastropoda adalah kelompok hewan dari filum moluska yang hidup di jenis substrat dari kasar ke halus. Kelimpahan gastropoda dipengaruhi oleh substrat dasar yang merupakan habitat dari gastropoda, serta kandungan nutrien yang berbeda pada tiap fraksi akan mempengaruhi kelimpahan Gastropoda yang berada di dalamnya. Oleh karena itu, perlu dilakukan penelitian mengenai hubungan substrat dengan kelimpahan Gastropoda, karena Gastropoda salah satu faktor penting untuk menjaga keseimbangan ekologi pesisir khususnya ekositem mangrove. Penelitian dilakukan di Hutan Mangrove Kulonprogo Yogyakarta bertujuan untuk mengetahui tipe substrat, kelimpahan Gastropoda dan hubungan kedua variabel tersebut. Penelitian dilakukan pada bulan April sampai dengan Mei 2017. Metode yang digunakan adalah metode deskriptif yaitu metode penelitian yang memberikan gambaran secara sistematis, faktual, akurat mengenai faktor-faktor dan sifat-sifat dari suatu daerah atau populasi. Metode pengambilan sampel substrat dan Gastropoda menggunakan metode Purposive Sampling Method pada 3 stasiun berbeda yaitu stasiun I pada bagian dekat pemukiman penduduk, stasiun II pada bagian dekat tambak, dan stasiun III pada bagian muara sungai. Hasil penelitian menunjukkan jenis substrat pada tiap stasiun adalah lempung dan lempung berdebu yang didominasi oleh fraksi lumpur (silt) dan pasir (sand). Jenis Gastropoda yang didapatkan berasal dari genus Littoraria, Natica, Faunus, Cerithium, Neritina, Polinices, Conus, Telescopium, dan Nerita. Meningkatnya prosentase fraksi pasir (sand) dan liat (clay) akan diikuti oleh meningkatnya kelimpahan Gastropoda, sedangkan untuk fraksi lumpur (silt) akan sebaliknya yaitu meningkatnya fraksi lumpur akan diikuti oleh menurunnya kelimpahan Gastropoda. Kata kunci: Tipe Substrat, Gastropoda, Mangrove, Kulonprogo Mangrove substrates formed by sands, silts, and clays. Gastropods is a group of animals of the phylum of mollusks lives on the type of substrate from rough to smooth. Gastropod abundance is affected by substrate which habitat of gastropods and nutrients influencing the distribution of gastropods. Therefore, it needs a deeper research about the correlation of substrate and the amount of gastropods , because gastropods are the importants factor of mangrove ecosystem. The research helds in Kulonprogo Mangrove Forest, Yogyakarta, and the goals are to know the type of substrate, the amount of gastropods, and the correlation among them.

Potensi sumberdaya perikanan tangkap di Indonesia, termasuk di pantura Jawa Tengah terindikasi telah mengalami tangkap lebih (overfishing). Kondisi ini salah satunya disebabkan oleh tekanan penangkapan yang didominasi oleh perikanan tangkap skala kecil yang banyak beroperasi di perairan pantai. Oleh sebab itu, pengelolaan dan pemanfaatan sumberdaya perikanan tangkap di pantura Jawa Tengah ke depan sudah saatnya dilakukan rasionalisasi dan menentukan kebijakan yang berkaitan dengan peningkatan armada perikanan tangkap yang mampu beroperasi di lepas pantai yang masih memberikan peluang pengembangan usaha perikanan tangkap. Tujuan penelitian ini adalah untuk menganalisis seberapa tinggi potensi dan tingkat pemanfaatan sumberdaya perikanan tangkap di pantura Jawa Tengah dan peluang pengembangan usaha perikanan tangkap tersebut di masa yang akan datang. Metode yang digunakan dalam penelitian ini adalah metode survei dan observasi lapangan di masing-masing kabupaten/kota pantura Jawa Tengah sebagai daerah penerima bantuan kapal >30 GT yang meliputi Kabupaten Pekalongan, Kota Pekalongan, Kabupaten Batang, Kabupaten Pati, dan Kabupaten Rembang. Analisis data untuk menduga potensi dan peluang pengembangan usaha perikanan tangkap di waktu yang akan datang dilakukan dengan menggunakan model bioekonomi dari Gordon-Schaefer (Sparre and Venema, 1999) berdasarkan data time series produksi ikan dan upaya penangkapan dari tahun 2006-2009. Hasil penelitian menunjukkan potensi sumberdaya perikanan tangkap di pantura Jawa Tengah, termasuk di beberapa kabupaten/kota pantura Jawa Tengah terindikasi telah mengalami overfishing. Pemanfaatan sumberdaya perikanan tangkap yang overfishing tersebut terbukti tidak efisien, karena dengan tingkat upaya penangkapan lebih besar dari EMSY, namun hasil tangkapannya justru lebih kecil dibandingkan CMSY, di mana dalam kurun waktu 2006 – 2009 produksi perikanan di pantura Jawa Tengah berkisar 153,698-195,636 ton. Dengan kondisi potensi sumberdaya perikanan tangkap di pantura Jawa Tengah tersebut, maka program bantuan kapal sebesar >30 GT dari pemerintah yang diperuntukan untuk mengurangi tekanan perikanan tangkap merupakan peluang pengembangan usaha perikanan tangkap. Meski demikian perlu dilakukan perbaikan, terutama dalam hal spesifikasi kapal dan perlengkapannya serta peningkatan pelabuhan perikanan yang memadai untuk fishing base dari kapal-kapal tersebut sehingga tujuan peningkatan produksi dan kelestarian sumberdaya ikan dapat dicapai untuk meningkatkan pendapatan nelayan. Kata kunci: produksi perikanan, model bioekonomi, pengelolaan perikanan tangkap skala kecil. The research on capture fisheries resources in north coastal of Central Java were to anticipate amount produce and effort of capture fisheries. Usefulness from this research expected to earn as reference of management of small scale fisheries and consideration alternative which can be taken for local government of Central Java Province. Primary data were collected from local fishers, while secondary data were collected from district and Marine and Fishery Services Central Java Province. Data series of 2006 to 2009 were also analyzed by bioeconomic analysis with surplus production model. The result indicate that condition of capture fisheries resources in North Coastal of Central Java were overfishing, included its several regency/city adjacent areas. The effort in developing fish capture has reached its boredom circumstance so this situation needs better maintenance and control toward the capturing activities. The policiy expected to minimize exploitation of fishery resources on coastal area, and the vessel can more further to off shore and oceanic area. The government as a policy maker on fisheries management for coastal fisheries must applicable precautionary approach by focusing on biology and economic aspects. Key words : fisheries product, bio-economic model, small scale fisheries management.
