Abstract

Yellowfin tuna (Thunnus albacares) has long been captured by commercial fishery in Makassar Strait using purse seine, trolling line and handline fisheries. It was probably it can cause over exploitation and decrease population structure for that fish. This study aimed to analyze the size structure of yellowfin tuna based on the positions of deep and shallow sea FADs (fish aggregating devices). The data consisted of fish length and weight ) and the size of gonad  maturation,  which were  collected from the  field observation . The  data were analyzed using histogram graph and t- test. The results indicated that the fish length caught in the deep and shallow sea FADs ranged from 30 to120 cm with the average of 101.39 ±2.49 cm, and from 105 to 170 cm with the average of 134.90 ± 1.90, respectively. The fish weight ranged from 20 to75 kg for deep sea FADs and ranged from 0.4 to 35 kg for shallow sea FADs. The first stage of gonad maturation on either female or male occurred at 118.88 cm forklength, where the smallest spawning size on  female  was 126.10 cm forklength.

Abstract

Squid is an economically important resource. Currently, squid populations, especially in the District Barru, were intensive exploited, that is feared to affect the population biology parameters. The study was conducted fromFebruary to April 2011. The sampling period was three times a week. The Samples were obtained using random collection from the fishermen catch using Rambo left net. Squid mantle length was measured to the nearest one mm.The parameters analyzed were age group, gonad maturity stage, growth, mortality, and exploitation rate. Squid population in Barru district consists of three age groups with the length of each mode of 51 mm, 98 mm, 133 mm formales, and 51 mm, 96 mm, 127 mm for females. The gonad maturity stage ranging from TKG I to IV for males and females, with the largest percentage of TKG TKG III (47.82% in males and 50.06% in females). The squid firstmaturity is reached at 94.3827 mm in long coat for males, and 59.6735 mm for females. Growth equation for males was Lt = 227 {1 - e -0.31 (t + 0.30)} and females are Lt = 196 {1-e-0, 37 (t +0.26)}. The total mortality rate (Z) is1.59 for males and 1.63 for females. The natural mortality rate (M) is 0.20 for males and 0.57 for females. The capture mortality rate (F) is 1.39 for males and 1.06 for females. The highest CPUE values reached in 1999 was 0.0022 ton per trip, while the smallest CPUE values reached in 2001 was 0.0001 tons per year. The greatest catches could be reached with fishing effort of 50 000 trips with catches of 50 tonnes.

Abstract

The use of semah fish with the local name pelian fish in nature is carried out using various methods, one of which is using tuba root plant poison. This tuba root poison is thought to have an impact on the biological condition of pelian fish and aquatic ecology. In connection with this, this research aims to analyze the size distribution, growth type and food habits of pelian fish. The research was conducted from June to August 2023 in West Krayan District, Nunukan Regency, North Kalimantan. The results of the study showed that the length distribution of pelian fish caught using tuba root plant poison was 30.626 ± 7.048 cm, with a weight of 786.531 ± 430.066 g. The growth pattern is negative allometric with eating habits consisting of moss at 44.57%, insects at 33.04%, pieces of fruit at 10.00% and unidentified at 12.39%. Moss and insects are the main food, while fruit is a complementary food. Based on the results obtained, pelian fish in nature can be caught using moss bait. The use of high doses of tuba root can cause damage to the fish's gills, which can cause fish death as a result of not being able to neutralize rotenone.
