Abstract

AbstractBubu fisheries have developed well in all Indonesian waters, especially in coastal areas that have coral reef and seagrass habitats. Generally, the commodities targeted for fishing are types of reef fish and seagrass beds that have a high selling value, such as snapper, grouper, baronang, yellowtail, lobster, octopus, and others. Bubu fishing gear or traps called bebihe local people are one of the fishing gear used to catch demersal fish or reef fish. The success of the bubu fishing operation is greatly influenced by the construction of the bebihe fishing gear itself and the treatment of the bait used. The use of seagrass bait, allegedly can increase the catching ability of the bebihe. However, scientific information on the use of seagrass as a bait for bebihe for fishing is not yet available. Therefore, the purpose of this study is to determine the effectiveness of seagrass baits with the comparison of kitefish in the operation of bebihe; and identify the types of fish caught.This research was carried out in the waters of Beeng Laut island, South Central Tabukan District, Sangihe Islands Regency; is based on experimental methods. Six bebihe units were operated during nine trips to collect data; where three units use seagrass bait of the type Thalassia hemprichii, and the other three units use kite fish bait; and then the catch data is analyzed by a t-test.The catch of bebihe during the study amounted to 363 heads, as many as 345 were caught with seagrass baits, and 18 were caught with kite baits. Analysis of the t-test showed that at t count = 5.480 > t table 0.05;8 = 2.306; where this explains that the use of seagrass bait on bebihe, gives a noticeablely different catch compared to kitefish bait.

Abstract

Sulawesi waters are directly affected by the dynamics that occur in the Pacific Ocean. The ENSO phenomenon that occurs in the Pacific Ocean can also be felt in the waters of the Sulawesi Sea. The dynamics of oceanographic parameters can cause climate change. The extreme impact of climate change is mainly the occurrence of rising temperatures and seasonal shifts. The purpose of this study is to analyze the variability of spatial and temporal anomalous distribution of sea surface temperature and chlorophyll-a. This study used monthly AQUA Modis image data, conducted by analyzing the spatial and temporal distribution of sea surface temperatures during the two decades of the period 2003 - 2022. This analysis is based on abnormal values obtained from subtracting parameter values from historical values (the average value of all data). The results of spatial variability analysis of sea surface temperature and chlorophyll –show anomalous variations occur in the western and transitional season periods I, while in the eastern season and transition II positive anomalous values dominate the eastern waters negative anomalies dominate the western waters opposite to chlorophyll – a. This study showed that there was an increase in sea surface temperature slope by 0.000840C / year while in chlorophyll - a there was a decrease in slope by 0.00072mg / m3 / year. Keywords: Spatial, Temporal, SPL, Chlorophyll – a, Climate Change. Abstrak Perairan Sulawesi mendapatkan pengaruh secara langsung dari dinamika yang terjadi di Samudera Pasifik. Fenomena ENSO yang terjadi di Samudera Pasifik juga dapat dirasakan dampaknya di perairan Laut Sulawesi. Dinamika parameter oseanografi dapat menyebabkan terjadinya perubahan iklim. Dampak ekstrem dari perubahan iklim terutama adalah terjadinya kenaikan temperatur serta pergeseran musim. Tujuan penelitian ini Menganalisis Variabilitas distribusi anomali spasial dan temporal dari suhu permukaan laut dan klorofil – a, Penelitian ini menggunakan data citra AQUA Modis bulanan, dilakukan dengan menganalisis sebaran spasial dan temporal suhu permukaan laut selama dua dekade periode 2003 - 2022. Analisa ini didasarkan pada nilai anomali yang didapat dari pengurangan nilai parameter dengan nilai historis (rerata nilai seluruh data). Hasil analisis variabilitas spasial suhu permukaan laut dan klorofil – a menunjukan variasi anomali terjadi pada periode musim barat dan peralihan I , sedangkan pada musim timur dan peralihan II nilai anomali positif mendominasi perairan sebelah timur anomali negatif mendominasi perairan sebelah barat sebaliknya dengan klorofil – a. Penelitian ini menunjukan bahwa terjadi peningkatan slope suhu permukaan laut sebesar 0,000840C/ tahun sedangkan pada klorofil - a terjadi penurunan slope sebesar 0,00072mg/m3/tahun. Kata kunci: Spasial, Temporal, SPL, Klorofil – a, Perubahan Iklim.

Abstract

As a small pelagic fish forming shoals in coastal waters, the bigeye scad (Selar crumenophthalmus Bloch, 1793), which has important economic value, is frequently captured in the FMA 716 of North Sulawesi waters, notably with small fishing gears such as purse seines. The intensiveness captures of the fish may affect the sustainability and continuity of the species. The research aims at analyzing some biological reproduction aspects of bigeye scad based on 400 captured samples, every 200 tails on May 2022 on Agust 2022, taken at random from the purse seine capture that landed at the coastal fishing port of Tumumpa, Manado. Data are analyzed referring to some common formulas, such as: M/F ratio, W-L relationship (W = aLb, W = weight, g), L = length (cmFL), a and b constants, condition factor (K), length at first capture (Lc50%). The length at first maturity (Lm50%) refers to Chodrijah and Faizah (2018) i.e., 18.91 cmFL for male and 17.98 cmFL for female as references. The value of Lm50% was compared with that of Lc50% for determining their worthiness. In general, there were 400 fish samples of both fishing seasons with the total weight of 64,554 g, where the length and weight were 21.56 ± 0.12 cm and 161.39 ± 3.53 g in average respectively, following the relation W = 0.0827 L3.5185 (r = 0.90; R = 81.0%). Of 400 samples, there were 176 males (44% of total samples) with the weight of 25,234 g (39.1% of total weight) where its length and weight ranged 20.93 ± 0.15 cm and 143.38 ± 3.81 g in average respectively, following the relation W = 0.1486 L 3.0725 (r = 0.86; R = 73.3%);. While the rest consisted of 224 females (56% of total samples) with a weight of 39,320 g (60.9% of total weight), where the length and weight ranged 22.05 ± 0.15 cm and 175.54 ± 4.80 g in average respectively, following the relation W = 0.0626 L 3.7273 (r = 0.89; R = 79.3%). The sex and weight ratios were 1:1.27 and 1:1.56, respectively. In May, there were 200 samples with a weight of 33,439 g (51.8% of the total weight), consisting of 96 males (48%) and 104 females (52%), with the weights of 42.4% and 57.6%, respectively. For 96 males, the length and weight of males ranged 20.94 ± 0.22 cm and 147.79 ± 5.52 g in average respectively, following the relation W = 0.1495 L 3.0770 (r = 0.86; R = 74.6%); while for 104 females, the length and weight of females ranged 22.25 ± 0.21 cm and 185.11 ± 6.89 g in average respectively, following the relation W = 0.0567 L 3.8076 (r = 0.90; R = 80.3%). The sex and weight ratios were 1:1.08 and 1:1.36, respectively. Without regarding gender, the length and weight ranged 21.62 ± 0.17 cm and 167.20 ± 5.15 g in average respectively, following the relation W = 0.0865 L 3.4926 (r = 0.91; R = 82.4%). In August, there were 200 samples with a weight of 31,115 g (48.2% of the total weight), consisting of 80 males (40%) and 120 females (60%), with the weight of 35.5% and 64.5% respectivel. For 80 males, the length and weight ranged 20.91 ± 0.20 cm and 138.08 ± 4.93 g in average respectively, following the relation W = 0.1519 L 3.0455 (r = 0.88; R = 76.9%); while for 104 females, the length and weight ranged 21.88 ± 0.20 cm and 167.24 ± 6.34 g in average respectively, following the relation W = 0.0791 L3.5471 (r = 0.88; R = 78.0%). The sex and weight ratios were 1:1.50 and 1:1.82, respectively. Without regarding gender, the length and weight ranged 21.49 ± 0.16 cm and 155.58 ± 4.71,,g respectively, following the relation W = 0.0838 L 3.5010 (r = 0.90; R = 81.2%). By using Lm50% reference 18.91 cm and Lc 18.33 cm, it was found that 69.0% of 200 fish samples are classified as the bigeye scad species, which are still worthy captures, with K ranges 1.82 - 2.73 (2.26 ± 0.02). Using Lm reference 18.91 cm and Lc 19.12 cm, it was found that 70.0% of 200 fish samples are classified as appropriate for catching bigeye scad. In this case, it means that the bigeye scad captured at two different fishing seasons from FMA 716 of North Sulawesi seawaters are still at a worthy size range to catch. The use of the given mesh size range of the webbing is highly effective in catching these fish. Keywords: bigeye scad, length-weight relationship, FMA 716, fish conservation
