Abstract

Shrimp commodities in Indonesia have been cultivated, either traditionally, traditionally plus, semi intensive, or intensively. One type of shrimp that is constantly strived to increase its production is the shrimp vaname (Litopenaneus vannamei). The environmental conditions of pond waters are closely related to pond water quality. One of the water quality parameters affecting the survival and growth of vaname shrimp is salinity. The study was conducted from May to June 2018 at the Fish Seed Hall (BBIP) Ghonebalano, Ghonebalano Village, Duruka District, Muna Regency. This study aims to determine the effect of water salinity on different media on the survival and growth of vaname shrimp. The study used a Completely Randomized Design with four treatments and three replications. Treatment A salinity 20 ppt, B treatment salinity 25 ppt, C treatment salinity 30 ppt and treatment D salinity 35 ppt. The results showed that the treatment had significant effect on the survival of the animals in the 95% confidence level where the survival in sequence, the treatment of A 87.50%, the treatment of B 83.33%, the C treatment 80.56% and the treatment D 69.44% . The treatment also had a significant effect on the growth of test animal at 95% confidence level. Successive growth was, treatment A 2.01 g, treatment B 1.91 g, treatment C 1,71 g and treatment D 1.51 g.

Abstract

Morphological identification as an alternative sex identification of dog conch without damaging the shell and viscera. The study aimed to identify the gender of the dog conch Strombus sp. by morphology. Samples were obtained from fishermen collecting dog conch on the coast of Madung, Tanjungpinang, Indonesia. Samples were collected by hand at low tide. To distinguish between male and female dog conch is done by looking at the shell structure morphologically without seeing the internal organs of the body shell. To see the gonads or reproductive organs is done by removing the whole dog conch by breaking the shell. The shell length was measured using by caliper a precision 0.01 mm. The length of the shell is the distance from the anterior edge to the posterior end of the shell. To know the sex ratio of dog conch type analyzed chi-square. The data obtained were analyzed descriptively. The results showed that of the total sample of 1124 individuals, obtained two types of dog conch are Strombus canarium and Strombus sp. The determination of the gender of morphological dog conch can be seen from the structure of the shell (width and slim). The wide shell shape signifies a female, a slim form of shell signifying a male. The sex ratio of dog conch type S. canarium and Strombus sp. males and females in different ratios.

Abstract

Penelitian dilakukan di Pulau Tobea dengan tujuan untuk menganalisis hubungan panjang-bobot dan faktor kondisi kerang lumpur. Data dianalisis untuk mengetahui hubungan panjang-bobot kerang lumpur dianalisis dengan menggunakan persamaan hubungan kuasa (power regresion) (Ricker, 1975) dan uji-T sedangkan faktor kondisi dengan menggunakan Metode Condisional Factor (CF) (King, 1995). Hasil analisis hubungan panjang-bobot kerang lumpur jantan digambarkan melalui persamaan W=0,0001.L3,366, dengan nilai korelasi (r=0,8559). Hasil uji-t koefisien b>3, dengan harga t=5,4053, diperkuat dengan hasil uji sigF=0,00<0,05, berarti bahwa antara laju pertumbuhan panjang dan bobot total kerang lumpur jantan tidak seimbang, yang bersifat alometrik positif atau alometrik mayor. Untuk kerang lumpur betina digambarkan melalui persamaan W=0,0001.L 3,381, dengan nilai korelasi (r=0,8865). Hasil uji-t koefisien b>3, dengan harga t=7,0811, diperkuat dengan hasil uji sig F=0,00<0,05 hal ini bahwa antara laju pertumbuhan panjang dan berat total kerang lumpur betina tidak seimbang, yang bersifat alometrik positif atau alometrik mayor. Hasil analisis condisional faktor (CF) kerang lumpur jantan, rata-rata sebesar 1,0319 (kisaran 0,4025-1,6613), kerang lumpur betina rata-rata sebesar 1,0203 (kisaran 0,4780-1,5625).  Hal ini menunjukkan bahwa faktor kondisi antara jantan dan betina rata-rata sebesar 1 yang berarti bahwa berat rata-rata kerang contoh lebih besar dibanding dengan berat rata-rata prediksi. Hal ini diakibatkan oleh kondisi lingkungan yang cukup baik dalam mendukung pertumbuhan kerang lumpur.
