The freezer trawler fleet operates with an average catch of 3,000 kilograms per hour, while a low presence of fresh-fish vessels is reported due to economic crisis and labor conflicts.

The start of the Argentine red shrimp (Pleoticus muelleri) harvest season for the year 2026 has recorded highly positive biological and commercial indicators. According to a report by Revista Puerto, the freezer trawler fleet is actively operating and strategically distributed throughout the authorized sectors, showing stable yields and an imminent opening of new fishing zones following favorable results from recent exploratory surveys.

Currently, vessels are concentrating their operations in sub-areas 4, 5, and 16, which remain open without showing signs of resource depletion. Although Sub-area 15 is formally open at the request of the province of Santa Cruz, no vessel activity has been recorded in that sector. The largest volume of the fleet is located in the northern sector of the restriction zone, repeating the distribution pattern observed last season.

According to technical data from industry operators provided to Revista Puerto, the generalized average yields reach approximately 3,000 kilograms per hour of trawling. While this catch volume is equivalent in both the northern and southern extremes of the restriction zone, the northern sector demonstrates higher density and capacity to sustain the concentrated activity of the commercial fleet.

Regarding the commercial size composition of the seafood, distinct differences are observed by zone:

  • Northern Sector: Displays optimal quality with an absolute predominance of the L1 category (large specimens), supplemented to a lesser extent by the L2 category.

  • Southern Sector: Registers smaller sizes, with scarce presence of the L1 category and catches composed equally of L2 and L3 classifications.

Furthermore, biological surveys carried out in sub-areas 8 (north) and 14 (south) concluded with favorable commercial results, with formal entry authorization for the fishing fleet anticipated within the coming hours. Likewise, official reports confirm that the hake (Merluccius hubbsi) bycatch ratio remains firmly below the allowable biological limit established by the enforcement authority, delivering a highly clean product on deck.

The distinctive feature of this 2026 production cycle is marked by a drastic reduction in the operability of fresh-fish vessels, whose current participation does not exceed a dozen units. Revista Puerto points out that this phenomenon is a direct response to the complex macroeconomic situation affecting the profitability margins of this specific fleet segment, compounded by unresolved internal labor disputes.

This low activity among fresh-fish vessels has had a direct impact on the scientific management of the fishery, limiting the collection of real-time data. In the current scenario, technical monitoring relies on just 3 onboard observers, which restricts the ability to quantify the yields achieved by shipowners in specific areas and weakens the information flow required following the relaxation of management measures implemented for the current season.

許可区域および調査区域における高水揚げに伴うアルゼンチンアカエビ漁期の優れた滑り出し

冷凍トロール船団は1時間あたり平均3,000キログラムの漁獲量で操業、一方で生鮮魚船の出漁は経済危機と労働争議により低迷と報道

2026年のアルゼンチンアカエビ(学名:Pleoticus muelleri、製品名:製品 marinos)の漁期開始は、生物学的および商業的に極めて良好な指標を記録している。Revista Puertoの報道によると、冷凍トロール船団は許可された各セクターに戦略的に配置され活発に操業しており、最近の資源調査(プロスペクシオン)で好結果が得られたことを受け、新たな漁区の開場が間近に迫っている。

現在、漁船は操業を第4、第5、第16小区域に集中させており、これらの区域は資源の枯渇の兆候を見せることなく開場を維持している。サンタクルス州の要請により第15小区域は正式に開場しているものの、同セクターにおける漁船の活動は記録されていない。船団の大部分は禁漁区の北側セクターに位置しており、前漁期の分布パターンと同様の動きを見せているが、生鮮魚船の隻数はより少なくなっている。

Revista Puertoに提供された業界関係者の技術データによると、トロール網の曳網1時間あたりの平均水揚げ量は、全般的に約3,000キログラムに達している。この漁獲容積は禁漁区の北端と南端の双方でほぼ同等であるが、北側セクターの方がより高い密度を示しており、商業船団の集中した操業を維持する能力があることを示唆している。

水揚げされた製品の商業サイズ組成(規格)に関しては、海域ごとに明確な差異が観察されている:

  • 北側セクター: 最適な品質を示しており、大型サイズであるL1カテゴリーが圧倒的な大半を占め、次いでL2カテゴリーがこれを補っている。

  • 南側セクター: より小型のサイズが記録されており、L1カテゴリーの存在は極めて稀で、漁獲物はL2L3の規格がほぼ半々で構成されている。

さらに、北側の第8小区域および南側の第14小区域で実施された生物学的調査は良好な商業成果で終了し、今後数時間以内に漁船団への正式な入域許可が下りる見通しである。同様に、公式報告によると、メルルーサ(学名:Merluccius hubbsi)の混獲比率は管理当局が設定した生物学的許容上限をしっかりと下回っており、甲板上には非常に混じり気のない状態でアルゼンチンアカエビが揚げられていると漁業者らはコメントしている。

この2026年の生産サイクルの際立った特徴は、生鮮魚船の稼働率が劇的に減少していることであり、現在の参加隻数は1ダース(12隻)に満たないRevista Puertoは、この現象について、当該漁船層の収益性に影響を与えている複雑なマクロ経済情勢に加え、未解決の労働組合との紛争が直接的な原因であると指摘している。

この生鮮魚船の活動低迷は、漁業の科学的管理に直接的な影響を及ぼしており、リアルタイムのデータ収集を制限している。現在のシナリオでは、確定したデータはわずか3名のオブザーバーからのものに留まっており、特定の海域で船主が達成した水揚げ量を数値化する能力を制限し、今漁期に適用された管理措置の緩和措置に伴い必要とされる情報流動を弱める結果となっている。これは、十分なデータがなければ船主が報告する良好な水揚げ量を定量化できず、関心のある海域が閉鎖されることにつながるため、生鮮魚船セクター自体にとっても結果的に問題となっている。

授权及探捕区红虾捕捞期开局喜人,产量保持高位

冻结拖网船队平均毎小时捕捞量达3,000公斤,而鲜鱼船由于经济危机和劳资冲突出勤率低。

2026年度管辖水域内阿根廷红虾(学名:Pleoticus muelleri,即 pesdados y mariscos)捕捞季的开局记录了极其喜人的生物和商业指标。根据Revista Puerto的报道,冻结拖网船队正在各授权区域内积极作业并进行战略性分布,捕捞产量保持稳定,且在近期探捕工作取得积极成果后,新渔区的开放已迫在眉睫。

目前,渔船正集中在允许捕捞的第4、第5和第16小区进行作业,目前这些区域未出现资源衰退的迹象;虽然应圣克鲁斯省的要求第15小区已处于开放状态,但并无渔船在渔区内作业。船队主要集中在禁渔区的北侧,这与去年的分布情况相似,但鲜鱼船的数量明显减少。

根据行业从业者向Revista Puerto提供的技术数据显示,拖网捕捞的平均产量普遍达到每小时3,000公斤左右。虽然这一体量在禁渔区的北端和南端大致相当,但所有迹象表明,最高度的集中发生在北侧区域,该区域能够承受大批商业渔船的集中作业并维持这一捕捞水平。

在商业规格(体长)组成方面,不同区域呈现出显著差异:

  • 北区: 表现出极佳的品质,大规格的L1类别占据绝对主导地位,其次是L2类别。

  • 南区: 规格偏小,L1类别极少,捕捞所得几乎由L2L3类别各占半数组成。

另一方面,在北部的第8小区和南部的第14小区进行的生物探捕均取得了良好的商业成果,预计在未来几小时内将正式批准渔船队进入。同样,官方报告证实,阿根廷无须鳕(学名:Merluccius hubbsi)的兼捕比例始终牢牢控制在执法当局规定的生物准许上限以下;渔民甚至表示,红虾被捕捞上甲板时非常干净。

2026年捕捞季的显著特点是鲜鱼船的作业率急剧下降,目前参与作业的渔船不足12艘Revista Puerto指出,这一现象直接源于影响该船队阶层利润率的复杂宏观经济形势,外加尚未解决的工会内部冲突。

鲜鱼船队的低参与度对渔业的科学管理产生了直接影响,限制了实时数据的获取。在当前形势下,经证实的数据仅来自3名随船科学观察员。考虑到本航季对该船队阶层已实施的管理措施放宽,这成为了一个突出问题,限制了量化船东在特定区域所获产量的能力,并削弱了必要的信息流。同时,缺乏覆盖率最终反噬了鲜鱼船行业自身:由于缺乏足够的数据,无法量化船东报告的良好产量,导致其感兴趣的区域有时不得不关闭,从而使其作业复杂化。
