Fish Habitats

Estuaries are widely recognized as key habitats supporting nearshore secondary production and catch of commercial fisheries. In Queensland, some of these coastal marine habitats are protected by the declared fish habitat programme run by the Department of Primary Industries and Fisheries. Expected environmental changes for Australian estuarine systems include reduced freshwater flow, increased sedimentation and with them, a loss of connectivity. At present, the relationship between the protected declared fish habitat and habitat connectivity remains unknown. By comparing long term coastal fish catch data with geomorphic characteristics of coastal habitats structural connectivity was previously identified as a potential driver of commercial fish catch in Queensland. An ecology landscape approach was used for this study to identify potential fish habitat hotspots along the coastline of Queensland thus allowing better defined networks of declared fish habitats. A comparison between this approach and the current declared fish habitats demonstrated potential deficits and provided important insights for fisheries management. Declared fish habitats should be placed in coastal habitats with high structural connectivity to ensure sustainability of fisheries in light of environmental changes.

Fish Habitats

<em>Abstract.—</em> The quality and quantity of habitats determine ecosystem productivity. Hence, they determine the potential fish productivity that sustains the fish harvests extractable from freshwaters and seas. Efforts to conserve and protect fish habitats are frustrated by key unanswered questions: which habitat types and how much must be protected to ensure natural self-sustaining fish stocks? Minns and Bakelaar presented a prototype method for assessing suitable habitat supply for fish stocks in Lake Erie, an analysis that can be used to address conservation issues. Here, the method is refined and extended, taking the assessment of habitat supply for pike <em>Esox lucius </em> in the Long Point region of Lake Erie as a case study. As with the previous study, much emphasis is placed on “learning by doing.” Because available inventories of habitat features are coarse and incomplete, improved guidelines for estimating habitat supply are expected from these prototype studies. The habitat supply method previously presented by Minns and Bakelaar is elaborated in three ways here: (1) the basic physical habitat assessment is derived from a remote-sensing inventory database; (2) methods of quantifying the thermal regime and integrating it with other habitat elements are examined; (3) habitat supply estimates are used in a pike population model, and pike biomass and production are simulated for the Long Point region of Lake Erie and then compared with available records. The roles of error and uncertainty are examined for all elements in the estimation and application of suitable habitat supply values. There is potential for supply measurement and analysis to guide fish habitat management.

Spawning Habitats

Abstract For marine fish, the choice of the spawning location may be the only means to fulfil the dual needs of surviving from the egg to juvenile stage and dispersing across different habitats while minimizing predation and maximizing food intake. In this article, we review the factors that affect the choice of fish spawning habitats and propose a framework to distinguish between ecological and evolutionary constraints. We define the former as the boundaries for phenotypically plastic responses to environmental change, in this case the ability of specific genotypes to change their spawning habitat. Processes such as predation, starvation, or aberrant dispersal typically limit the amount of variability in spawning habitat that fish may undergo from 1 year to the next, and thus regulate the intensity of ecological constraints. Evolutionary constraints, on the other hand, refer to aspects of the genetic make-up that limit the rate and direction of adaptive genetic changes in a population across generations; that is, the potential for micro-evolutionary change. Thus, their intensity is inversely related to the level of genetic diversity associated with traits that regulate spawning and developmental phases. We argue that fisheries oceanographers are well aware of, and more deeply focused on, the former set of constraints, while evolutionary biologists are more deeply focused on the latter set of constraints. Our proposed framework merges these two viewpoints and provides new insight to study fish habitat selection and adaptability to environmental changes.

Caspian Roach

The article shows the assessment of fishing conditions of roach catches (the number of fishing grounds, fishing gears, catches, catches per unit of fishing effort, fishing intensity, etc.) at the main fishery objects of the Volga delta. There has been made the analysis of structure of size and gender composition of roach from commercial and amateur catches. The results have shown a depression of the population with negative dynamics in future. There have been determined main negative factors affecting the state of roach stock: unfavorable hydrological regime, incoordination in terms of commercial and amateur catches, limits of catch and size. In such circumstances the major purpose is to create a fishing regime, when maximum pass of fish spawners to spawning grounds is provided. The article proposes organizing a special regime of fishing roach with the aim to introduce additional limitations to the commercial fish catch, the main point of which is a transition from fine-meshed seines to medium-meshed seines in the day, when the water level in the Astrakhan region achieves an index mark as 350 cm. This measure will allow assuring a maximum pass of roach spawners to spawning grounds. A similar interdiction must be valid for amateur fishing. It should be noted that this interdiction is a provisional measure allowing to preserve and reproduce roach population.

The Impact ◽

Swept Area

The Magnuson-Stevens Fishery Conservation and Management Act mandates U.S. fisheries minimize adverse effects of fishing on essential fish habitat (EFH). The Gulf of Maine (GoM) American lobster fishery is the most valuable U.S. fishery, and can deploy more than three million traps annually. To date, the impact of this fishery on benthic EFH has not been addressed quantitatively. To evaluate the impact of the GoM lobster fishery on EFH, lobster fishing effort was incorporated into a model linking habitat susceptibility and recovery to area impacted by fishing gear; the Swept Area Seabed Impact model. Impact to EFH was localized along the coast and highest along mid-coast Maine. Upwards of 13% of the benthos is in the process of recovery, but between 99.92 – 99.96% of initially affected habitat fully recovers. These estimates suggest that lobster fishing negligibly contributes to accumulation of EFH damage in the GoM due to the expansive area fished and the small footprint of each trap. Identifying areas of persistent impact is crucial in developing effective fisheries management for critical marine habitats.

Damaging the environment and high level of fish exploitation are feared for the extinction of fish habitats. The extinction of fish habitat resulted to the extinction of local languages. In the context of tradition, the preservation of ecological lexicon, one of which is found on sampiran of the pantun. This study discusses the existence of fish lexicon contained in the pantun’s sampiran. The purpose of this study is examining the level of survival of the Malay language of Barus related to the fish lexicon. The threat of this research uses ecolinguistic theory. The method used is a mixed research method between quantitative and qualitative research methods. Based on the research data, there are 10 fresh water fish lexicon and 30 sea fish lexicon originating from 40 pantun’s couplet. From 40 respondent’s answers, it is known that the marine fish lexicon is in the defensive category, slightly decreasing, that is 23.3%. Meanwhile, the freshwater fish lexicon is classified as threatened.Rusaknya lingkungan dan tingkat eksploitasi ikan yang tinggi dikuatirkan akan berdampak pada punahnya habitat ikan. Konsekuensinya itu juga berdampak pada punahnya bahasa lokal. Pada konteks tradisi, pelestarian leksikon ekologi, salah satunya terdapat pada sampiran pantun. Penelitian ini membahas keberadaan leksikon ikan yang terdapat pada sampiran pantun. Tujuan penelitian adalah untuk mengkaji tingkat kebertahanan bahasa Melayu Barus berkaitan dengan leksikon ikan. Ancangan penelitian ini menggunakan teori ekolinguistik. Metode yang digunakan adalah metode penelitian gabungan (mixed methods) antara metode penelitian kuantitatif dan kualitatif. Berdasarkan data penelitian terdapat 10 leksikon ikan air tawar dan 30 leksikon ikan laut yang berasal dari 40 bait pantun. Dari 40 jawaban responden diketahui bahwa untuk leksikon ikan laut berada dalam kategori bertahan, sedikit mengalami penurunan, yaitu 23,3%. Sementara untuk leksikon ikan air tawar masuk pada kategori terancam.
