NRS-1300 | Card register of rents on oyster leases [State Fisheries Branch]

This series consists of oyster lease rent cards arranged in lease number order. The cards were produced by the Fisheries and Oyster Beds Branch (later known as the State Fisheries Branch) between 1901 and 1940. A single lease is recorded on each card. As such there can be multiple cards for the same lessee. The main purpose of the cards is to record the lessee, location of lease, rent paid on the lease and period of the lease. Some cards also record consignments of oysters produced and spats (an oyster in its larval stage) removed.The series is split into two runs, those cards that have been marked as "expired", "surrendered" or "refused" leases and those that have not. The two runs could be interleaved with the numbering gaps in each corresponding to the contents of the other. Up until 1936 the cards (oyster leases) are a given single number however from 1936 onwards the year followed by a single number is used e.g. 36/299.Information provided on each card includes: Number (of lease); Name of applicant or lessees; Locality; Foreshore or area (in yards); Date of lease; Term (years); Annual Rental (in pounds); Rental payments / year / amount / date paid; Communications / date received / precis; On the back of the card: Oyster consignments / date / bags (number); Spat removals / date / bags placed on lease / bags removed from lease / lease from which or to which removed.The same type of information as found on the lease cards can be found in volume format in NRS 1299 Oyster lease rent registers. These volumes however are not split into expired and current leases, they instead list all leases in lease number order. However from lease number 16377 onwards only the card register was used.To find the lease number of a particular lessee NRS 1298 Personal oyster lease register can be used. This register lists lessees alphabetically by surname and lists the oyster lease numbers for each lessee.

本系列档案为按租约编号排序的牡蛎租约租金卡。此类卡片由渔业与牡蛎床分局（后更名为州渔业分局）于1901年至1940年间编制。每张卡片仅记录一份租约，因此同一承租人可能对应多张卡片。

此类卡片的核心用途为记录承租人信息、租约位置、租约已付租金及租约期限。部分卡片还会记录已产出牡蛎的托运情况以及移除的牡蛎幼体（spats，即处于幼虫阶段的牡蛎）。

本系列分为两个序列：标记为“已过期”“已终止”或“已驳回”租约的卡片，以及未作此类标记的卡片。两个序列可能存在交错情况，各自的编号空缺恰好对应另一序列的存档内容。

1936年之前，卡片（牡蛎租约）采用单一编号格式；1936年起则采用“年份/编号”的格式，例如36/299。

每张卡片包含的信息如下：租约编号；申请人或承租人姓名；所在区域；岸线或区域（单位：码）；租约生效日期；租约期限（年）；年租金（单位：英镑）；年度租金支付情况/金额/支付日期；往来通信/收文日期/摘要。卡片背面的信息包括：牡蛎托运情况/日期/托运袋数；牡蛎幼体移除记录/日期/投放至租约区域的袋数/从租约区域移除的袋数/移除来源或接收的租约编号。

与租约卡片信息一致的内容，可在NRS 1299《牡蛎租约租金登记簿》的装订卷宗中查阅。但该卷宗未区分过期租约与有效租约，而是按租约编号顺序归档所有租约信息。不过从租约编号16377起，仅采用卡片式登记簿进行记录。

若需查询特定承租人的租约编号，可查阅NRS 1298《个人牡蛎租约登记簿》。该登记簿按承租人姓氏的字母顺序排序，并列出每位承租人对应的牡蛎租约编号。
