The catching efficiency of traditional traps: Ayunan and Tamba were tested in Sungai Batang River, South Kalimantan of Indonesia. Trials consisted of 320-trap hauls/type using 1-day submersion time of 24 hr. The baited traps sampling accounted for 82 specimens assigned to 5 species of 5 families. There was a large variability in number of catch between prawns and fish species collected (T=2.318, P<0.05). The prawns catch was represented by only the species Macrobrachium rossenbergii with total of 53 and 1,015 g weight. The prawns weight of Tamba was significantly higher than that of Ayunan (T=3.453, P<0.01).The fish catch composed of Mystus gulio 79%, Osteochilus hasselti 10%, Hypostomus plecostomus 7%, and Macrognathus aculeatus 3%, with total weight ranged from 35 to 560 g. A clear difference was found in catching efficiency. Comparative fishing trials showed that Tamba collected specimens were 1.8 times higher than Ayunan (T=2.223, P<0.05). Catch per unit effort for Tamba ranged from 58.13 to 80.00, and for Ayunan ranged from 5.31 to 7.19. The gear modifications and various treatments (e.g. bait odor, light) are necessary to be taken to increase their relative catching efficiency.

The purpose of this study is to determine the effect of the escape gap of cylinder folding trap on catch per unit effort (CPUE), trap rate, composition, and size of fish caught in the coastal waters of Tuban Regency. The research was conducted in November 2019 by deploying 60 units in ten experimental fishing trips at different locations. The traps were 20 units without escape gap, 20 units with an escape gap of 3 cm x 6 cm, and 20 units with an escape gap of 4 cm x 7 cm. Overall, the experiments resulted in a collection of 22 species of marine organisms, such as swimming crabs (33% of total weight), snails, shrimps, crabs, fishes (55% of total weight), and cuttlefish. The highest CPUE was found for the traps with escape gaps of 4 cm x 7 cm, i.e., 9.18 gr/trap/trip. There was no significant difference in the total catch, the weight of catches, trap rate, and catch per unit effort (CPUE) among the three types of traps.

<p>Ayunan is the trap most widely used by public Sungai Batang Village, in addition to the unique shape of this tool also has an extensive capacity to accommodate good catches of shrimp and fish species. In addition to the village of Sungai Batang, at the Hulu Sungai region there is also the ayunan that looks different from contained in Sungai Batang Village.</p><p>This study aims to (1) know the difference between shrimp of catch amor ayunan and box ayunan, and (2) to determine the catch other than shrimp. The results of research, treatment A (amor ayunan) shrimp catches as many as 1464 , with a total weight of 9100 grams. Treatment B (box ayunan), shrimp catches as many as 1443 , with a total weight of 7730 grams. Type of main haul shrimp (<em>Macrobrachium rosenbergii de Man</em>) and Freshwater Shrimp (<em>Palaemon sp</em>), with by catches are  Lundu (<em>Mystus gulio</em>) with a total of 18 and total weight of 215 grams, sapu-sapu (<em>Hypostomus plecostomus</em> ) 2 , weighing a total of 560 grams, Puyau (<em>Osteochilus hasselti</em>) 3 , weighing a total of 35 grams, telan (<em>Macrognathus aculeatus</em>) 2 , weighing 810 grams.</p>Bamboo and rattan as materials to make the ayunan has a weakness because odor (smell) is not good (bangai) and therefore contributes to the catch. To overcome this weakness it is advisable to replace the wire with the basic material.

Abstract This study aims to determine the effect of escape gap on catch composition, CPUE, and trap rate at the northern coast of Tuban Regency. The research was conducted by ten trips of experimental fishing at different locations in November 2019. A total of 60 units of cube folding traps were installed long line, consisting of cube folding traps without escape gaps, cube folding traps with escape gaps 6x3 cm, cube folding traps escape gaps 7x4 cm, 20 units, respectively. The fish catch composition consists of 18 species of 6 groups, i.e., fish, swimmer crab, shrimp, hermit crab, and snail. Fish were the most dominant group captured by cube folding traps in the northern coast of Tuban Regency (59.7%), followed by swimmer crab, snail, crab, shrimp, and hermit crab. The highest catch per unit effort was found in cube folding traps with escape gaps 7x4 cm as much as 6,94 gr/traps/trip. The highest of the trap rate (18%) was obtained in the cube folding traps without escape gap. There was a significant difference (p=95%) in the weight of fish catches and CPUE between cube folding traps without escape gaps and the cube folding traps with escape gaps 7 x 4 cm.

Population dynamics and CPUE of Alosa genus with emphasis on Alosa braschnikovi (Borodin, 1904) on the coasts of Golestan Province, Iran. Biodiversitas 19: 59-66. The aim of this study was to compare relative abundance and catch per unit effort of members of the Alosa genus (family: Clupeidae) in the fishing grounds of Gomishan and Miankale in Golestan coasts. Sampling operations were done by beach seine during 2011 to 2012. A total of 240 fish were collected. Identified species in Gomishan were: Alosa braschnikovi (Borodin, 1904) and A. saposchnikovi (Grimm, 1887). The most abundant species in this region were individuals of A. braschnikovi. The highest length and weight in the region were 35.6±1.85 mm and 447.8±57.43 gr for Alosa braschnikovi in Gomishan. Besides the two mentioned species, A. kessleri (Grimm, 1887) was caught in Miankale coasts. The most abundant species again was Alosa braschnikovi in this region. The highest length and weight were 33.12±3.18 cm and 362.5±99.57 gr for Alosa braschnikovi in Miankale region. The results showed that mean of CPUE in Miankale was higher than in the Gomishan region. The comparison of sex ratio for shads showed that males were dominant against females. Also, the comparison between species showed that the highest values for length, and weight of fish species compared belonged to Alosa braschnikovi. Among the Alosa braschnikovi fishes caught, individuals were in the range of 2 to 5 age groups within the two compared regions and most abundant were observed in 4 age groups.

Determining bait type might be one of the most important factors that influence the amount and size of the fish catch in marine recreational fishery. To this end, the relationships between two types of natural bait and catch per unit effort (CPUE), yield per unit effort (YPUE), fish size and condition (K=W/TL3) were evaluated in recreational fishery İzmir Bay (Middle Eastern Aegean Sea, Turkey). The most abundant angling species in Turkish coasts; annular sea bream (Diplodus annularis), blotched picarel (Spicara flexuosa), two banded sea bream (Diplodus vulgaris) and bogue (Boops boops) were collected by anglers between September 2006 – February 2007 with using baits; onyx (Solen vagina), and sardine (Sardina pilchardus). The average CPUE and YPUE of hooks baited with onyx were significantly higher than the bait sardine. Eventhough the averages of specimens caught with bait sardine were bigger than onyx except for bogue but, total length-frequency distributions were revealed some differences only for annular sea bream and blotched picarel between two baits. High conditioned individuals of bogue were caught with bait sardine and the rest of the other species with onyx.

Mangroves provide habitat to a variety of fish species, potentially enhancing fish production in small-scale fisheries. Fish production ecosystem services have been correlated with mangrove area and perimeter in many tropical locations; however, nothing has been published linking small-scale fish catch and mangrove attributes in the southern Caribbean Sea. We correlated environmental variables with experimentally-derived catch per unit effort (CPUE) and richness of fishes in the Colombian southern Caribbean Sea, an area not directly connected with other productive coastal habitats. Concurrently, we measured mangrove attributes (area, perimeter, above-ground carbon), water quality (salinity, total dissolved solids), and water column productivity parameters (chlorophyll a, seston, zooplankton biovolume). Mangrove area and zooplankton biovolume were the main factors influencing fish species richness. Mangrove area was positively correlated with catches for three of the most common fish species in the local artisanal fishery: Ariopsis canteri Acero P, Betancur-R, and Marceniuk, 2017, Mugil incilis Hancock, 1830, and Sciades proops (Valenciennes, 1840), which represent about 22% of the total regional annual catch. Our results suggest causal links between mangrove habitat and fishery production through a mangrove trophic contribution. Ariopsis canteri appears to be a mangrove-dependent species and M. incilis a mangrove- associated species. These results support managing or preserving mangroves in the most extensive areas in the southern Caribbean to sustain small-scale fishery resources used mainly for community sustenance where alternative resources are limited.
