TL;DR: In this article, integrated analysis models provide a tool to estimate fish abundance, recruitment, and fishing mortality from a wide variety of data, and the flexibility of integrated analysis model allows them to be used in a wide range of applications.

TL;DR: The exploitation history and spatial gradients in fishing pressure explained most patterns in abundance and diversity, including the absence of strong compensatory increases, and Ecological corridors and large-scale protected areas emerged as potential management options for elasmobranch conservation.
Abstract: Sharks and rays' abundance can decline considerably with fishing. Community changes, however, are more complex because of species interactions, and variable vulnerability and exposure to fishing. We evaluated long-term changes in the elasmobranch community of the Adriatic Sea, a heavily exploited Mediterranean basin where top-predators have been strongly depleted historically, and fishing developed unevenly between the western and eastern side. Combining and standardizing catch data from five trawl surveys from 1948–2005, we estimated abundance trends and explained community changes using life histories, fish-market and effort data, and historical information. We identified a highly depleted elasmobranch community. Since 1948, catch rates have declined by >94% and 11 species ceased to be detected. The exploitation history and spatial gradients in fishing pressure explained most patterns in abundance and diversity, including the absence of strong compensatory increases. Ecological corridors and large-scale protected areas emerged as potential management options for elasmobranch conservation.

TL;DR: Habitat factors could not account for these ARNB results for target fish, but did influence abundance patterns of non-target fish, and the lack of abundance gradients of target fish at Balicasag may reflect reduced fishing outside the reserve since it was established.
Abstract: 1. An abundance gradient from high inside to low outside a no-take marine reserve may indicate net emigration of adult fish from the reserve (spillover). 2. We examined spatial patterns of abundance of fish across two 900 m long sections of coral reef slope at each of two small Philippine islands (Apo and Balicasag). One section sampled the entire length of a no-take reserve and extended 200-400 m outside the two lateral reserve boundaries. The other section, without a reserve, was a control. The reserves had had 20 (Apo) and 15 (Balicasag) years of protection when sampled in 2002. 3. Significant spatial gradients of decreasing abundance of target fish occurred across only one (Apo Reserve northern boundary = ARNB) of four real reserve boundaries, and across none of the control boundaries. Abundance of non-target fish did not decline significantly across reserve boundaries. 4. Abundance of target fish declined sharply 50 m outside the ARNB, but enhanced abundance extended 100-350 m beyond this boundary, depending on fish mobility. 5. Density of sedentary target fish declined 2-6 times faster than density of highly vagile and vagile target fish across the ARNB. 6. Habitat factors could not account for these ARNB results for target fish, but did influence abundance patterns of non-target fish. 7. The lack of abundance gradients of target fish at Balicasag may reflect reduced fishing outside the reserve since it was established. 8. Apo Reserve had a gradient of abundance of target fish across at least one boundary, a result consistent with spillover.

TL;DR: This study details the dynamics of a population of great scallops Pecten maximus within a closed area and an adjacent fished area off the Isle of Man over a 14 yr period, finding that fisheries for relatively sedentary and long-lived species such as P. maximus appear to be particularly suitable for this type of management.
Abstract: Despite the current interest in using closed areas for fisheries management, few studies have actually examined the benefits for invertebrate fisheries such as scallops. This study details the dynamics of a population of great scallops Pecten maximus (L.), within a closed area and an adjacent fished area off the Isle of Man, over a 14 yr period (1989 to 2003). Scallop densities were very low in both areas when the closed area was set up, but increased at an accelerated rate over time within the closed area. Scallop densities also increased on the adjacent fishing ground, but not to the same extent. Consequently, the density of scallops above the minimum legal landing size (110 mm SL) was more than 7 times higher in the closed area than in the fished area by 2003. There was also a shift towards much older and larger scallops in the closed area and, correspondingly, lower estimates of total mortality. Experimental dredging of 2 plots within the closed area confirmed that fishing drove these differences in population dynamics and structure. These patterns of scallop density, age and size structure resulted in the exploitable biomass (adductor muscle and gonad) of scallops being nearly 11 times higher in the closed area than in the fished area by 2003, and the reproductive biomass was 12.5 times higher. This is significant for fisheries management because the build up of high densities of large P. maximus individuals enhanced local reproductive potential and therefore the likelihood of export of larvae to the surrounding fishing grounds. Along with these direct benefits of closed area protection, juvenile scallops had higher survival and individual growth rates in the closed area, apparently in response to reduced fishing disturbance. Although juvenile scallops are not subject to direct removal by fishing, protection during this critical phase therefore appeared to assist the recovery of the closed area population. In summary, this study joins a growing number indicating that the use of closed areas offers a range of benefits over more traditional methods of managing fisheries. Fisheries for relatively sedentary and long-lived species such as P. maximus appear to be particularly suitable for this type of management.
