Kawakawa (Euthynnus affinis) is one of the highly favored mackerel tunas caught in Java Sea. The increase in demand due to local consumption and export eventually increases fishing that is proportional to the exploitation status. To maintain the fish resource, a scientific study should be carried out on the fishing grounds and the exploitation status of kawakawa. This study was carried out for 3 years, i.e. in March to October 2017, June to December 2018, and February to November 2019 at Pekalongan National Fishing Port in Pekalongan, Central Java, with 9,511 fish as the study objects. The data analysis was carried out by observing the fishing grounds using GPS and through interview. In addition, the exploitation status was analyzed using FISAT II application and ELEFAN program. The fishing grounds were mostly coastal waters with 15–55 cm sized kawakawa. The size of the first caught (Lc) of the kawakawa in this area ranged from 26.9 cm to 38.4 cm. The fish recruitment occurred all year long, peaking in Apr at 15.97% and Juli 13.62%.The fish natural mortality (M) was smaller than its fishing mortality (F), while its exploitation status was 0.66 (overfished), meaning that the current fishing efforts should be reduced by 32%. The other management efforts that can be carried out are among others conservation, keeping the fishing grounds outside the spawning grounds, and controlling the mesh size.

“…Pertumbuhan ikan dapat diprediksi dengan mengukur rasio pertambahan panjang dan berat ikan yang menunjukan tingkat penambahan massa otot/daging, kesehatan dan produktifitas ikan (Agustina et al, 2019). Aktifitas penangkapan ikan secara berlebihan akan mempengaruhi penurunan rata-rata pertambahan panjang maupun berat ikan dalam suatu populasi yang menggambarkan rata-rata laju pertumbuhan populasi tersebut.…”

Lisong tuna (Auxis rochei) is one of high economic potential value of fish because of its abundance and often found in the fish market in Ampenan. Evaluating the impact of fishing to the growth pattern of length-weight of tuna is needed to ensure the sustainability of lisong tuna population. It is feared that the high intensity of tuna (A. rochei) fishing can cause growth disturbances and a decrease in local tuna populations. This study aimed to determine the relationship between the weight and length of lisong tuna (A. rochei) to their growth patterns in the fish market of Ampenan. Thirty individuals of lisong tuna were collected from two fish markets, Bintaro and Kebon Roek, in Ampenan. The equation of Linear Allometric Model is used to evaluate the length and weight relationship in growth patterns of lisong tuna. This study resulted in the positive allometric growth pattern of lisong tuna with slope value more than 3 (b=3.79). It indicated that the lisong tuna which were collected in Bintaro and Kebon Roek markets have a weight growth rate faster than their length growth rate. It means that the lisong tuna sold in Ampenan markets is quite fleshy and has a good growth rate.

The main construction of the purse seine is wings, body and bag. The mesh size of each part is different. The wings have a mesh size of 10.16 cm, body 7.62 cm and bag 2.54 cm. Mesh size greatly affects the size of catch. Fish morphometric which is strongly influenced by mesh size is fish body girth. A mesh size larger than the body girth will allow fish to escape from the net and a smaller mesh size will trap fish by gilled, snagged or wedged. The purpose of the study was to distribute the frequency of the length and body girth of mackerel, analyze the relationship between length, body girth and mesh size of the purse seine. The research method used is experimental fishing for 2 trips. Analysis of the data used is linear regression, the formula for the width of the purse seine mesh opening and determination of body girth coefficient based on mesh size. The results showed that the minimum value of mackerel length was 35 cm and the maximum value was 57 cm. The highest length frequency distribution was at the size of 41-43 cm. The minimum value of fish body girth is 23 cm and the maximum value is 44 cm. The highest value in the body girth frequency distribution of fish was 29-31 cm. The relationship between length and body girth has a value of y=0.72x–1.91. The correlation value of body girth and mesh size is 0.82 and has an average body girth coefficient of 0.084 in the bag, 0.251 body and 0.335 wings. The fish body girth coefficient value is smaller than the standard. This means that mackerel caught tend to be wedged in the wings, gilled in the body and snagged in the bag.Key Words: Body Girth; Mackerel; Mesh Size; Purse Seine
