This allows filter net has the potential to be non-selective fishing gear about the fish size and the target species catch. If the fishing gear allowed, hence its existence will ultimately have a negative impact on the sustainability of fisheries resources, especially in coastal waters. The objective of this research is to calculate compositions and proportions of the main catch, bycatch and discard of the filter net. It is expected by knowing the composition and proportion of the main catch, bycatch and discard can provide an overview of the pressure on the stock and sustainability of fisheries resources in waters where it is operated. This research was used survey method. A series of survey activities was conducted directly in the field to identify and count species of filter net‘s fishing catches. Based on the main catch, bycatch and discard of the filter net, it shows that Sergetes similis is the dominant species caught bythe filter net(98.455%). The main catch for Escualosa thoracata reaches 1.354%. Besides, the main catches that were caught were Metapenaus monocerus, Parapenaeopsis sp, Panulirus sp and Paneeus monodon with the catch percentage ranging from 0.011 to 0.024%. Percentage of by-catches reached 0.04-0.00004% of the 24 species caught and the catch removed was around 0.001-0.0005% of the 3 species caught.</p><p class="TubuhTulisanAll"><strong><em>Keywords:</em></strong><strong><em> </em></strong><em>bycatch, discard, filter net, fisheries resources</em><em>, main catch</em><strong></strong></p><p class="TubuhTulisanAll" align="center"><strong>ABSTRAK</strong></p><p class="Abstrakisi">Gombang memiliki ukuran mata jaring pada kantong berukuran kecil. Hal ini memungkinkan alat tangkap gombang berpotensi menjadi alat tangkap yang tidak selektif terhadap ukuran ikan dan jenis yang menjadi sasaran tangkapannya. Apabila alat tangkap ini dibiarkan, maka keberadaannya pada akhirnya akan memberikan dampak yang negatif terhadap keberlanjutan sumberdaya ikan terutama di perairan pantai. Tujuan penelitian ini adalah untuk menghitung komposisi dan proporsi hasil tangkapan utama (<em>main catch</em>), hasil tangkapan sampingan (<em>bycatch</em>) dan hasil tangkapan yang dibuang (<em>discard</em>).Diharapkan dengan mengetahui komposisi dan proporsi hasil tangkapan utama, sampingan dan yang dibuang dapat memberikan gambaran tentang tekanan terhadap stok dan kelestarian sumberdaya perikanan di perairan dimana gombang dioperasikan.Metode yang digunakan dalam penelitian ini adalah metode survei.Serangkaian aktivitas survei dilakukan secara langsung di lapang untuk mengidentifikasi dan menghitung jenis spesies yang tertangkap oleh alat tangkap gombang.Berdasarkan persentase hasil tangkapan utama, sampingan dan buangan per jenis, menunjukkan <em>Sergetes similis</em> merupakan spesies yang dominan tertangkap oleh alat tangkap gombang (98,455%).

The effect of temperature on the swimming performance of jack mackerel Trachurus japonicus was examined in a flume tank by measuring the swimming endurance time and heart rate. The lower swimming performance was observed at 10°C (the lowest temperature tested), manifesting as the shortest endurance time and the slowest maximum sustained speed. ECG measurements of the heart rate under free-swimming conditions at zero flow velocity revealed a temperature effect, with 25.3 beats/min observed at 10°C, 38.9 at 15°C, and 67.2 at 22°C. The heart rate also increased with swimming speed to maximum levels of 60, 125, and 208 beats/min, respectively, at these three temperatures. Heart rate recovery times measured after the fish had been swimming at prolonged speed tended to increase with temperature, while a negative correlation resulting in relatively short recovery times was observed after swimming at close to the burst swimming speed at each water temperature.
The research was conducted from March to June 2015 during the rainy season and the Village were located in four Selatpanjang South Village, East Selatpanjang, Selatpanjang City and West Selatpanjang Tebing Tinggi District of Riau Kepulauan Meranti. The purpose of this study was to analyze the potential availability of rainwater, water needs population in the region Selatpanjang 2030, the development of rainwater harvesting systems and outlines the relationship with environmental, social and economic. The method used in this study was the observation by analyzing rainfall, debit mainstay, drainage coefficient (α), population projections, the ratio of the number of residents with clean water needs as well as rainwater harvesting design. The results showed that the potential of rainwater in the area amounted to an average Selatpanjang 1724.8 mm/year, of the four sub regions Selatpanjang rain water can be harvested amounted to 17.248 billion liters/year. The four village Selatpanjang region in 2030 amounted 49 471 inhabitants population in predicted, so, it is necessary to clean water for 534 286 800 liters for three months. So if managed and well developed, the rain water can meet the need of clean water Selatpanjang community throughout the year. How to manage it is by developing the rainwater harvesting system with a system of individual, communal for three families and communal for five families and build ponds to accommodate the run-off. Economically, the use of rainwater harvesting system is cheaper than buying water each summer, primarily communal system for three families. Socially aspects that bring positive habits and reduce conflicts between neighbors and the environment, with the principle of sustainable utilization of natural resources. The quality of rain water in Selatpanjang meets the criteria for clean water, so it can be used as a source of clean water.
