Analisis Aspek Dinamika Populasi Ikan Cakalang (Katsuwonus Pelamis) yang di daratkan di Pelabuhan Perikanan Pantai (PPP) Pondokdadap Sendangbiru Kabupaten Malang Jawa Timur ANALISIS ASPEK DINAMIKA POPULASI IKAN CAKALANG (KATSUWONUS PELAMIS)
Abstract
Skipjack tuna (Katsuwonus pelamis) is one of the largest export commodities in Indonesia
Pondokdadap Beach Fishing Port. Analysis of aspects of population dynamics
is an important step taken to determine the condition of skipjack fish stocks
sustainability in the waters of the Indian Ocean. Long data collection is done at TPI
Sendang Biru during March - July 2022 with a total sample of 3,875 individuals.
The length frequency distribution data (cm) were analyzed using the FAO-ICLARM Stock program
Assessment Tools (FISAT) to estimate parameters of growth, mortality, exploitation,
recruitment, yr/br and stock prediction. The results of the population parameter analysis are as follows, length
asymptote (L∞) 68.39 cm; growth rate coefficient (K) 0.31 per year and theoretical age (t0) -
0.42 years. Total mortality value (Z) 4.27 per year; natural mortality (M) 0.66 per year and
fishing mortality (F) 3.61 per year. Exploitation rate (E) 0.85 per year incl
overexploited. The peak of recruitment occurred in June with a value of 16.53%. yr analysis
get a value of 0.019 per year and br 0.054 per year. Maximum potential estimated value
sustainable (MSY) of 46622 tons with an optimum fishing effort (FMSY) value of
539 trips. The exploitation rate has a value of 457% and the utilization rate is 1%.
