Feasibility of Pole-and-Line Fishery: Comparison of Milkfish ( Chanoschanos, Forskal ) and Anchovy ( Stolephorussp ) as Live Bait

— This study was conducted from May to July 2019 in Bitung City, North Sulawesi Province using pole-and-line vessels in Bitung Fishing Port (PPS Bitung).The method used in this study is a survey method with case studies. Some of the analyzes used: (1) comparative descriptive analysis; (2) business analysis; (3) criteria analysis for investment.The objectives of this study are to compare the level of financial feasibility anddetermine the level of difference between pole-and-line fishing businesses that use milkfish seed and those that use anchovy. The calculation results of business analysis of pole-and-line businesses that use milkfish seed and anchovy are based on the criteria of the businesses in gaining profits and a fast payback period, with an ROI value greater than the capital expense. Investment feasibility is based on the criterion value of an investment, that is NPV>0, Net B/C > 1, and IRR value > 10% interest rate so that pole-and-line business units that use either one of those live baitsmeet the requirements, especially business units that use anchovy. However, milkfish seed still deserves a development as an alternative bait, especially in the condition in which anchovy is difficult to find.


I. INTRODUCTION
Bitung is one of the centers of skipjack fishing in Indonesia. Pole-and-line or huhateisan environmentally friendly fishing gear usually used to catch tuna, mackerel tuna, and skipjack tuna in Bitung. Based on the International Seafood Sustainability Foundation data (ISSF, 2010), pole-and-line catch is dominated by skipjack by 57%, yellowfin tuna 27%, bigeye tuna 11%, and albacore 5%. Huhategreatly relies on the availability of live bait in nature (wild bait). Wild baits often used are anchovy (Encrasicholinaheteroloba and Encrasicholinadevisi) and fingerscalesardine (Sardinella fimbriata). Those wild baits can be obtained from floating baganfishermen and small boats (pajeko). In 2014, there were about 104 pole-and-line vessels in Larantuka, North Flores, but only about 50 vessels were able to operate because of various problems, one of which was the declining availability of live bait obtained from floating bagan fishermen. This condition is caused by the limitation of bagan, which can only operate during a dark moon. Moreover, the population of baitfish tends to decrease because of overfishing since the fish is used not only as live bait but also as the cheapest consumption fish in local markets (Tokan, 2017). The competition to get the same resources between fishing gear Lampara and purse seine to meet the needs of home industry, as well as bagan which is considered as an environmentally friendly fishing gear also contributes to the decrease of live bait availability in the sea. To overcome this problem, some pole-and-line vessels in Larantuka and Bitung tried to use cultivated milkfish seed as live bait. Therefore, it is important to analyze the comparison of pole-and-linefishing businesses to determine the differences in financial feasibility between those businesses that use milkfish seed and those that use anchovy as live bait. vessels in Bitung Fishing Port (PPS Bitung). The method used in this study is a survey method with case studies (Arikunto, 2000). Study objects consist of four vessels, namely KM River, KM. Primadona, KM. CahayaBintang, KM. CahayaDaulinsa with 25-27 GT which were examined using milkfish and anchovy. The time of fishing and the fishing ground were assumed to be the same for each vessel. The selection of respondents was adjusted to the needs of the study using a purposive sampling method (Sugiyono, 2006). The respondents in this study were the owner and crew of pole-and-line vessels, five people in total. In addition, other stakeholders namely two representatives from the Fisheries Service and four company employees were also interviewed to enrich the data. Thus, there were 11 respondents in total. Data collected consists of primary and secondary data. The primary data were obtained through direct observation while the secondary data were obtained using literature search method.

Comparative Descriptive Analysis
Comparative descriptive analysis provides thematic comparative frequency distributions in the form of tables and figures. This analysis aims to observe the tendency and comparison of business feasibility between pole-andline businesses that use milkfish seed cand those that use anchovy as live bait.

Business Analysis
Components used in business analysis include production costs, gross and net income gained from the pole-and-line fishing business. Various analyses are conducted in business analysis, namely analyses of business income, revenue and cost balance (R/C), payback period (PP), and Return of Investment (ROI) (Hernanto, 1989).
Business income can be calculated using the following formula: µ = where: µ = Profit = Total revenues = Total expenses with the following criteria: If TR > TE, the business activity gets profits. If TR<TE, the business activity does not get profits. If TR = TE, the business activity is at the break-even point, i.e business activity does not get profits or losses.
Revenue and cost balance (revenue-cost ration) can be calculated using the following formula: / = with criteria: If R/C > 1, the business activity gets profits. If R/C < 1, the business activity gets loss. If R/C = 1, the business activity does not get profits or loss.
Payback Period (PP) is calculated using the following formula: Net Present Value (NPV) is calculated using this formula: where: = Benefitsof a project in the yeart = Project cost in year t = Technical lifespan of a project = Applicable interest rate The feasibility criteria are: If NPV ≥ 0,means the investment is feasible If NPV < 0 means the investment is a loss or not feasible to be implemented.
Internal Rate of Return (IRR) can be calculated using the following formula: where: = Discount factor that produces a positive present value. = Discount factor that produces a negative presentvalue. Net Benefit Cost Ratio (Net B/C) is calculated using this formula (Kadariah,2001).:

The feasibility criteria are: B/C > 1 means that the investment is feasible to be implemented B/C < 1 means that the investment is not feasible to be implemented,and B/C = 1 means that implementation decisions depend on the investor.

III. RESULTS & DISCUSSION A.Pole-and-Line Catching Unit
Bitung is the main base of pole-and-line vessels in North Sulawesi. There were 37 pole-and-line vessels in 2017. These vessels are generally made of wood sized 20-100 GT, most of which are vessels sized 50-100 GT.Pole-andline vessels in Bitung Fisheries Port are made of wood with a fishing spot at the bow of the vessel. The Bow of the vessels is specially designed with a flying deck to ease the anglers. The bow is also designed rather high so that the fish caught can slide down to the center of the vessel near the catch tank. This design is intended to ease the handling of the catch. Pole-and-line has huhate fishing gear made of a fishing rod, fishing line, and fishing hook. Each vessel has 15-20 crews/workers. Machines used consist of three engine units, namely the main engine, water circulation engine, and lighting engine. Navigation equipment consists of GPS Furuno GP32, compass, and SOG-VMS. The vessel is also equipped with water spray pipes with flattened ends to maximize the spray reach. These pipes are placed in the bow of the vessels under the flying deck or angler seats. There are eight in total, two each in the left and right sides of the vessel, and 4 in the bow.Live bait tanks are placed in the hull of a vessel. There are two tanks of the same size, that is 1.5 m long, 1 m wide, 1.5 m high and have a maximal capacity of 20 buckets or ± 400 L. The bait tank is the characteristic of apole-and-line vessel. It is equipped with water intake and discharge holes that function as a water circulating system. In addition, there is also a bait pot to ease the throwing of live bait. Pole-and-line vessel also has two units of hatches served as catch storage sized 1 long, 1 m wide and 1.2 m high, with capacity of 2 tons and two units of hatch for ice storage sized 1 m long, 1m wide, and 1.2 m high with capacity of 2 tons (60-70 ice blocks) each which are placed on the deck in front of the pilothouse. The ice hatches can also be used as storage if the storage hatches are unable to contain all the catches. Other parts of the vessels are the pilothouse, engine room, 1,000-L fuel tank, break room for crews, clean water tank, kitchen, and toilet.  (Naamin, 2000). The main type of live bait that fishermen often use is anchovy (Stolephorussp), which, in this study, is compared to milkfish seed (Chanoschanos, Forskal) as a substitute when the main bait is scarce. Anchovy (Stolephorussp) is obtained from bagan fishermen around the path to the fishing ground. The price is IDR 20,000 per 20-L bucket. A vessel usually loads 15 -20 buckets on each operation, depending on the capacity of available tank and fund. On the other hand, milkfish seed are obtained from milkfish farmers in North MinahasaRegency since there are no milkfish farmers who sell milkfish seed (Chanoschanos, Forskal) in Bitung City. The price is IDR 300 per fish. A vessel usually uses 12 bags in which a bag contains 1000 milkfish seeds.

There is a significant difference between the priceset by company and the local price used by fishermen to sell fish to retailers in fish season. These prices are set based on an agreement on the cutting operational costs. On average, the income of pole-and-line using anchovy is IDR 877,731,765 per year while the income using milkfish seed is IDR 702,499,480 per year. This indicates that the income of pole-and-line using anchovy is greater by 11.1% than that of pole-and-line using milkfish seed. Pole-and-line vessels, either using anchovy or milkfish seed, have three fishing days (trip) per month in total, and 36 trips per year on average. The optimal fishing operation is nine months.

Investment Costs for Pole-and-Line Fishing Business
Analysis of business feasibility is carried out to examine the financial and economic benefits of activities of each business unit so that the investment used will provide maximal benefits to fishermen's income. Investment costs are the initial costs incurred by the owner (fishermen) to start the business.  /dx.doi.org/10.22161/ijeab.45.43  ISSN: 2456-1878 www.ijeab.com Page | 1571

Fixed Costs for Pole-and-Line Fishing Business
Fixed costs are costs that must be incurred even if there is no fishing operation. The components of fixed costs for pole-and-line business consist of maintenance costs and depreciation of vessels, machinery, navigation equipment (7 years), fishing gear (2 years), sibu-sibu (3 years), bait tank, water sprayer (5 years), and pickup car (10 years).

Calculation Results of Business Analysis
Analysis of pole-and-linefishing business is conducted to determine the level of business success that will be achieved financially and the feasibility of business development.

F. Profit-Sharing System
After profit sharing (50% : 50%) between the vessel owner and the crew as a whole, based on the calculation results of crew's income in skipjack catching business in the waters of Bitung City, with the price of fish set by the company, then the average net income gained by the owner of the vessels is IDR 24,381,438 per pole-and-line vessels per trip for vessels that use anchovy as live bait and IDR 19,513,874 per trip for vessels using milkfish seed. The average income of the crew for vessels with anchovy is IDR 2,159,795 per person per trip and IDR 1,996,923 per person per trip. Assume that there are three trips in a month, then the average income of the crew of pole-and-line vessels using anchovy is IDR 6,479,384 and IDR 5,990,768 for the crew of pole-and-line vessels that use milkfish as live bait. Based on the calculation, it can be concluded that the income of these fishermen is feasible since it has exceeded the provincial minimum wage set by the Provincial Government of North Sulawesi, which is a minimum of IDR 3,051,076 per month.
IV. CONCLUSION Based on financial feasibility, a significant difference in income can be observed between pole-andlinefishing businesses that use milkfish seed and those that useanchovy as live bait. The results of the business and investment feasibility indicate that pole-andlinefishing businesses that use anchovy as bait are still prospectively more profitable. However, the results also indicate that pole-and-linefishing businesses in Bitung City that use milkfish seed as bait still deserves a development.
