The Research about the food habits and length-weight relationship of Labiobarbus leptocheilus Valenciennes was conducted from May to September 2010. The aims of this research were to find out the food habits and to analyze the growth pattern of Labiobarbus leptocheilus Valenciennes. The sampling of fishes was conducted on May 2010 in the Gajah Mungkur Reservoir, Central Java. The sampling of fishes was conducted by using survey on the landing place of fishes (TPI Mina Tirta). The methods of analysis of food habits by using the Index of preponderance. The results of this research obtained were 19 samples of Labiobarbus leptocheilus Valenciennes, the length between 15-20 cm, with the weight between 40-90 grams. Labiobarbus leptocheilus Valenciennes had the negative allometric growth pattern (b <3). The laboratory analysis of food habits showed that the food habits of Labiobarbus leptocheilus Valenciennes were detritus with Index of Preponderance (IP) 82.95% and plankton with IP 17.05%.Keywords: food, habits, length-weight, relationship, Labiobarbus leptocheilus

Portunus pelagicus (blue swimming crab) is one of the important economical marine commodities produced from Indonesian coastal waters that has increasing market demand among fishery commodities. The purpose of this research is to reveal the relationship of carapace width and weight, the growth pattern and the carapace width-weight ratio of P. pelagicus crabs at two different research sites in Manado Bay. The benefits of this study, can be a reference for further studies on blue swimming crabs, P. pelagicus, and information obtained in this study could become important information needed for the maximum sustainable utilization of blue swimming crab, P. pelagicus.This research was conducted at two locations, namely Kelurahan Bahu, Sub-district of Malalayang with coordinates of 1 ° 27'49.86 "North and 124 ° 49'35.79" East and second location in Tumumpa Dua, Sub-district of Tuminting with coordinates 1 ° 31'14.51"North - 124 ° 50'28.67"East. Samples of blue swimming crabs were collected by deploying traps which are placed at 5-7 meters with the distance between traps 10 meter. Traps were placed at 17.00 pm and lifted on the next day at 06.00 am. Measurement of the width of the carapace conducted by using the ruler with 0.1 cm accuracy and weight measurement using the scales with 0.1 gram accuracy.The correlation value obtained for the wide and weight relationship of blue swimming crabs in the Sub-district of Malalayang is 0.953 for males and 0.898 for females. In Kelurahan Tumumpa Dua, Sub-dis ittrict of Tuminting 0.829 for males and 0.920 for females respectively. Based on these values the increase in the width of the carapace will affect the weight gain of the crab. The growth pattern of P. pelagicus crab in Kelurahan Bahu, Sub-district of Malalayang and Tumumpa Dua Sub-district Tuminting showed negative allometric growth pattern with b <3 value which means faster carapace growth compared to the weight of crab. From the result of chi square test on wide body and weight relationship analysis, is found same for both locations with value x2 table = 7.815 <x2 count = 112.3134. This is presumably due to one of the external factors is the availability of food.Keywords: Rajungan, growth pattern, Manado Bay AbstrakPortunus pelagicus merupakan salah satu komoditi hasil laut ekonomis penting yang dihasilkan dari perairan pantai Indonesia dengan permintaan pasar terhadap komoditas rajungan yang terus meningkat. Adapun tujuan penelitian ini yaitu mengetahui hubungan lebar berat rajungan P. pelagicus, pola pertumbuhan rajungan P. pelagicus dan perbandingan lebar berat rajungan P. pelagicus di dua lokasi penelitian yang berbeda di Teluk Manado. Manfaat penelitian ini, dapat menjadi bahan acuan untuk studi lebih lanjut mengenai rajungan P. pelagicus serta infomasi yang didapat dalam penelitian ini bisa menjadi bahan kajian untuk pemanfaatan rajungan P. pelagicus secara maksimal serta berkelanjutan.Penelitian ini dilaksanakan pada dua lokasi yakni di Kelurahan Bahu Kecamatan Malalayang dengan koordinat 1°27'49.86"LU - 124°49'35.79"BT dan lokasi kedua di Kelurahan Tumumpa Dua Kecamatan Tuminting dengan koordinat 1°31'14.51"LU - 124°50'28.67"BT. Pengambilan sampel dilakukan dengan alat tangkap bubu yang diletakan pada kedalam 5-7 meter dengan jarak antara bubu 10 meter. Bubu diletakan pada pukul 17.00 wita dan diangkat pada esok harinya pukul 06.00 wita. Pengukuran lebar karapas menggunakan mistar dengan ketelitian 0,1 cm dan pengukuran berat tubuh menggunakan timbangan 0,1 gr.Nilai korelasi yang didapat untuk hubungan lebar berat rajungan P. pelagicus di Kelurahan Bahu Kecamatan Malalayang 0,953 untuk jantan dan 0,898 untuk betina. Di Kelurahan Tumumpa Dua Kecamatan Tuminting 0,829 untuk jantan dan 0,920 untuk betina. Berdasarkan nilai tersebut pertambahan lebar karapas akan berpengaruh pada kenaikan berat tubuh dari rajungan. Pola pertumbuhan rajungan P. pelagicus di Kelurahan Bahu Kecamatan Malalayang dan di Kelurahan Tumumpa Dua Kecamatan Tuminting menunjukan pola pertumbuhan yang bersifat allometrik negatif dengan nilai b < 3 yang berarti pertumbuhan karapas lebih cepat dibandingkan pertambahan berat rajungan. Dari hasil analisis chi square lebar berat tubuh, sama untuk kedua lokasi penelitian dengan nilai x2 tabel =  7,815 < x2 hitung = 112,3134. Hal ini diduga karena salah satu faktor eksternal yakni  ketersediaan makanan.Kata  kunci : Rajungan,  Pola pertumbuhan, Teluk Manado.

This study is aimed to determine length-weight relationship and condition factor of common ponyfish in Pabean Bay, Indramayu. The study was carried out for one year, from April 2016 to March 2017. Fish collection were caught using gillnet and set net. total of 154 individual fishes were caught, the fish samples ranged from 18 - 141 mm in length and 0.05 – 41.35 g in weight. The length-weight relationship of ponyfish throughout a year was W = 7x10-06 L3,1983. The result indicated that the growth pattern of fish was positive allometric. The relative condition factor of ponyfish was varied from 0,67 – 1,42 AbstrakPenelitian ini bertujuan untuk menentukan hubungan panjang bobot dan faktor kondisi ikan petek yang ada di Teluk Pabean, Indramayu.

C. quadricarinatus (red claw) has important economic value either for consumption or as ornamental crustacean, has been  cultivated, and introduced to many waterways outside its natural habitat. In Tondano lake, C. quadricarinatus has developed and become fishing target  using traps and spearguns.  The purpose of this survey is to describe the freshwater lobster catching using traps, and to know the length-weight relationships, growth pattern and condition factor. The study was expected to use as information on the presence of C. quadricarinatus Tondano Lake. Catches were red claw, C. quadricrinatus, marble sleeper Oxyeleotris marmorata, Mud gudgeon Ophieleotris aporos, Mozambique tilapia Oreochromis mossambicus and African sharptooth catfish Clarias Gariepinus. Length-weight relationship of C. quadricarinatus was W = -1.8005 + 4.2765 log L for males, W = -1.2978 + 3.6524 log L for females, respectively, and W = -1.5631 + 3.9848 log b for combined sexes. They had positive allometric (A +) growth. Condition factor ranged from 0.60-1.43 with an average of 1.071 ± 0.17 for males and 0.46-1.36 with an average of 1.027 ± 0.18 for females, 0.59-1.642 withan average of 1.22± 0.21.Keywords: fishing, length-weight, growth pattern, fishing gear, Kakas district, MinahasaAbstrakC. quadricarinatus (red claws) mempuyai nilai ekonomis penting baik komsumsi maupun sebagai krustasea hias dan  telah banyak di budidaya serta di introduksi ke banyak perairan  di luar habitat aslinya. Di Danau Tondano, C. quadricarinatus telah berkembang biak dan menjadi target penangkapan nelayan mengunakan alat tangkap bubu dan alat tangkap tura sejenis tombak sambil menyelam. Tujuan penelitinan ini ialah untuk mendeskripsikan penangkapan lobster air tawar C. quadricarinatus menggunakan alat tangkap bubu, hubungan panjang berat, pola pertumbuhan dan faktor kondisi. Hasil penilitian ini diharapkan dapat digunakan sebagai informasi keberadaan lobster air tawar C. quadricarinatus di Danau Tondano. Hasil tangkapan yang didapat adalah lobster air tawar, ikan Betutu, ikan Payangka, ika Mujair dan ikan Lele Dumbo. Hasil hubungan panjang berat lobster air tawar di dapat jantan : W=-1,8005+4,2765 log L, betina : W=-1,2978+3,6524 log L dan gabungan ( jantan & betina) : W=-1,5631+3,9848 log L. Pola pertumbuhan ketiganya ialah allometrik positif (A+) dan faktor kondisi jantan berkisar 0,60-1,43 dengan rata-rata1,071±0,17, betina berkisar 0,46-1,36 dengan rata-rata 1,027±0,18, dan gabungan (jantan dan betina) berkisar 0,59-1,642 dengan rata-rata1,22±0,21.Kata Kunci : Penangkapan, Hubungan panjang berat, Pola pertumbuhan, Kecamatan Kakas
